B&H has underwater equipment from Ikelite, Amphibico, Quest, EWA-Marine, and others. Seacam Subsea Systems makes the DV/S2 housing for the TRV900 which also requires the Citizen 2.9" LCD monitor. Light & Motion Industries makes some high-end housings. The most unusual housing I've seen is the Ocean Brite which is large enough to house the camera with the LCD open. The SeeBubble is a very inexpensive housing, as a kit or do-it-yourself project, and has links to many other inexpensive options. I have heard of only one kind of underwater microphone. There is a photo and video competition at the SEASPACE scuba convention in Houston.
If you just need protection from showers, Portabrace has some rain slickers (custom models for TRV900, PD100 + wide-angle lens, and VX2000 among others). There is another one made by ScubaCam , available in the USA from Band Pro Film/Video which Carrol Lam wrote about.

"Ewa camera and camcorder housings are made of double laminated, high frequency welded, UV resistant flexible PVC. Ports feature plano-spherical optical quality glass with o-ring seals. They are available for Auto Focus and Manual Focus 35mm SLR cameras with or without flashes, motordrives and other accessories, as well as several compact 35mm point and shoot models. Practical operating depth with Adventure Series housings is 90', with Master Series glove housings is 60'. Ewa bags are available for many makes and models of camcorders. Ideal for snorkeling and shallow dives, these housings can also be used as rain/foul weather protection. Practical operating depth is 30'."
"Please call for help selecting the proper Ewa housing for your camera or camcorder."
Many models for various cameras are listed along with the prices which range from $53 to $269. Most of them are $269. The SONY TRV-900 camcorder is not specifically listed and is probably newer than this catalog.

The camera and wideangle lens, oriented to the front housing lens nice and tight, and the camera didn't seem to move within the bag based on the resultant video. Included foam pads can balance the fit nicely (I felt like the model I got(VST), was made for the trv900). There is an included lead weight bag, that can be inserted inside, or attached to the straps on the exterior.... both offering an increased camera stability. I had no need for weights this trip, as I only submerged a few feet at best (coooold hands and arms). But I certainly will use them, when I shallow scuba. The front housing lens is 3.5 in in diameter. Negatives of the ewa were controls...you need to push/click/slide through the heavy poly side walls. But hey, its a lot better then the footage I could have taken above the surface, and I still have 1,000. to 1,400. in my pocket. -jim
Subject: Sony Sports Pack SPK-DVF2 From: "Leonard Fintelman" (Leonard.Fintelman at net.HCC.nl) Date: Sat, 1 May 1999 15:24:21 +0200
I can tell you that it is certified to work down to 2 meters under water, but at the shop I was confidentially told it used to be certified down to 5 metres, which was changed to 2 as people tried it scuba diving at around 10 metres (you know how these things work), which didn't work.....
Let me describe the important points/parts/controls. It has an external stereo microphone and one has externally a zoom button (T-W), a mode selector (off/camera/play), a red start rec button and a seperate external photo button. The photo button allows you to write to tape only (you can not select "memory", so no capture to memory card). Only the last is maybe a bit dissappointing, but no more than that. However given the fact that there is an extenal photo button and the camera itself has to be switched to "camera" while installing it in the housing, maybe putting it on "memory" instead, would make it a (progressive scan, I have a Simple 40 mb 5v flash pcmcia card) digital photo camera "only", if one would like. I guess it won't harm to try if one is not interested in "video" during a session with the sportspack.
On the left is an extractable externally mounted mirror, which can reflect the LCD screen backwards if the LCD screen is opened flat on the camera with the lcd screen pointing outwards. One can also choose to view from the back of the casing though the viewfinder. In that case the mirror can remain collapsed flat on the side of the waterproof housing. The two connectors inside the housing are for mic and Lanc. The waterproof housing has a wrist and a shoulderstrap, just like with the TRV 900 itself.
I will use the SPK-DVF2 for filming while (deckmounted) Seakayaking and underwater filming of (kayak) eskimorolls (training/education) in a swimmingpool only, so I do not intend to go "diving". The other uses will be during particularly bad weather in the Scottish mountains (happens more often than one would like) and filming in sandy (beach) conditions.
Greetings from Holland,
From: Terry Langille (Terry.W.Langille at bridge.bellsouth.com)
Leonard Fintelman provided me with some great info and pictures on the Sony Sport Pack, not sold in the US. I located a couple of dealers in North America [...] Berger Brothers of New York imports the units in small quantities, and marks them up a whopping 100% above retail, not including shipping and insurance. Several Sony dealers in Canada could get them. Surprisingly, the best price I found was $260 US, from the Sony Store in Halifax, NS.
I should also mention that I collected all the info I could on full featured dive housings in the event that the Sport Pack was impossible to get, and although I'm not currently in the market to buy one, a clear winner for the TRV900 pooped out of the crowd of 5 or 6 housing manufacturers. Undersea Video makes a cast polyurethane housing only slightly larger than the camcorder itself (they report a 1/4" hull standoff from the camcorder surface). The housing, called the T-9, has a Control-L (LANC) module epoxy-sealed enabling most of the camera's controls with no thru-hull seals required. Because the case has so little empty space in it, bouancy weights are minimal. The unit comes with external dome port, color filter, and an optional wide angle internal lens to maintain focus throughout the zoom range. Access to the case is via an O-ring sealed Lexan backplate held in place with sping latches. The case, because of the sealed electronics and minimal hull openings can be washed out as a routine maintenance function. I talked briefly with the owner, who admitted to a 7-week backorder and 7-day-a week production. $1089 US. Weight with camera and neutral bouyancy weights, 12lbs.
My SPK-DVF2 was shipped from Henry's Of Toronto, a large retailer that advertisies international shipping. Henry's downtown Toronto location has a toll free, 800 461-7960. Their net address is www.henrys.com. My order confirmation originated from address email@example.com. They take the major credit cards, and ship via UPS or Purolator. They were professional and polite, but didn't invite me to stay with them if I'm ever in Toronto. (sigh) Price quoted was $399CDN + $15 shipping, subject to US Customs duty and Customs brokerage fee. Sport Pack was shipped 6/15 and delivered 6/23, with additional charges of $78.20 US Customs and $34.00 brokerage fee. Total delivered price, $426.20 US.
Subject: [TRV900] Adventures with a Sport Pack Date: Mon, 02 Aug 1999 06:47:04 -0400 From: Terry Langille (twl1 at jps net)
The Sport Pack relies on a press fit seal to maintain it's watertight integrity, rather than a brute force o-ring sealing system. The seal kept things dry, at least down to the 3 foot depth I took it. The goal of the day was to film a baby's first openwater swim (float, actually), and get some action shots from a 4-boat expedition up the lake and into the river that feeds the lake as far as a jet cycle could go.
Lesson #1 - I tightened the tripod screw that holds the Sport Packs mounting shoe to my TRV900 with my fingers. The shoe and the tiny plastic tab that lets you move the tripod screw to several different positions when setting the Sport Pack up for different models of Sony camcorder is rather fragile looking, and seemed to demand a light touch. Wrong.
Although I wrapped the entire Sport Pack in a large towel and secured it inside my Yamaha's waterproof front compartment full of neoprene wetsuits and booties, enough vibration reached the Sport Pack to loosen the tripod screw. The camera, resting on it's side, made contact with the Sport Pack's inner surface at the outer boss around the TRV900 thumbwheel and a tiny area of the LCD screen hinge, scuffing the inner polished surface of the case. Fortunately, the scuffing is cosmetic only, no bigger than a thumbtack, but it taught me lesson #1. Today I'll install those little dime-sized neoprene bumpers that are sold as scratchproof feet for lamps, wherever tha case might make contact.
Lesson #2 - It caused no problems, but Sony's warning not to leave the case in the sun for more than 5 minutes should be heeded. I found it advisable to loosen one of the Pack's latches every few minutes to equalize pressure. Obviously this should only be done on dry dry land. A couple of times, the air pressure buildup was enough to cause an audible pop when the latch was released.
Lesson #3 - Completely remove the lens cap, to avoid a noise and scratch issue. It gave me no problem, but while crossing some hard wake, I could easily hear the lens cap rattling about. Did the rattling make it to tape? No, but only because of lesson #4.
Lesson #4 - Don't become so preoccupied with the hazards facing your TRV900 that you forget to put a fresh tape in your camcorder. With all of the 'new' concerns to consider, I ended up 21 miles from the put-in point with a tape that had only 5 minutes on it. So much for carrying 4 or 5 extra tapes around.
Lesson #5 - There is no way I'll hang the TRV900 off the nose of my boat. The rough water and the pace of the group led to some really hard jolts that would easily fracture the tripod mounting boss on the Sport Pack. It's time to find a lipstick cam.
By the way, the 5 minutes of video and audio I did get were great.
Subject: Housings for Scuba: Amphibico, Gates, Ikelite From: mhuston at concentric net Date: Thu, 29 Jul 1999 10:53:04 -0400
One of the main decisions to make is whether to choose a housing with manual or electronic controls. Opinions and tastes vary widely, but most professional underwater videographers tend to opt for manual controls.
The pros of manual controls are: manufacturers can design the housing to access any control (not just what electronic interfaces can address); they tend to be more durable and less prone to malfunction, more dependable; their position by nature has to be proportional to where you're used to finding the same controls when using the camera above water; there tend to be more controls/options than on electronic
The pros of electronic controls are: central location of the controls, usualy on the handgrips, can make them easier to operate, easier to aim; there's not as much to learn, and it's more evident what the controls do; there's no risk of poor alignment making the controls non-functional (i.e., with manual controls if they aren't lined up perfectly, they can fail to push the buttons to activate the control).
Amphibico makes a very good electronic housing ($1300 est. street price) called the Dive Buddy. It has very good balance and buoyancy (you want it to be as close to neutrally buoyant underwater as possible), and the controls are easy to use. It doesn't have all the controls needed for underwater shooting, however, most notably white balance mode selection (you have to choose that before putting it in the housing, and not being able to adjust as you go deeper can be an issue). For the price, however, it's the best I believe in the $1000-$1500 range.
Amphibico has recently come out with a new housing called the Navigator 900, ($2000) which I have on order but is backordered so I haven't used it yet . It is a manually controlled housing, and sports a wider range of controls, including white balance, full menu wheel control, and manual focus (the Dive Buddy just has access to the autofocus button on the TRV900, the idea being that you leave it in manual then push the auto button when needed, which works pretty well). It also has internal filters (Dive Buddy is external), which is a big benefit since you can not only switch from regular to color corrected shooting (the latter being necessary below about 15-20 feet), but can also switch from regular to macro lens (can't do that with the Dive Buddy). Another intriguing feature is a flip-out LCD viewscreen on the housing itself; all other housings don't let you use the viewscreen or at least not with it flipped out. Many housings have accessory plugin screens you can buy separately, but this is the first I've seen with it incorporated. It looks and seems like a great housing, but if I get it in time for next month's dive trip we'll see.
Gates makes a manual housing called the Diego that is also excellent ($1500 for standard port or $1900 including wide angle port). They're a very small company so it can be hard to get a hold of one due to supply/demand issues, but it's worth the effort. It's about as compact as you can get for a housing for the TRV900, great balance/buoyancy, and sufficient controls (including white balance). The controls are simple and easy to use after a few initial dives. It has an easily interchangeable wide angle dome port option (can't change underwater), and has an internal flip filter for the color correction vs. standard filter. Before I heard of the upcoming Navigator 900 this is what I had decided to buy, and if the Navigator isn't as great as it sounds I would be very happy ending up with the Gates housing.
Ikelite is the third manufacturer that made the "final cut" in my research (Ikelite, est. price $1100) Unlike the others mentioned, Ikelite housings are made of clear acrylic rather than annodized aluminum. One nice feature about this is that you can see the camera's LCD screen through the housing (not flipped out, but flush with the camera). While this is a nice sounding feature, in application it doesn't add a whole lot, since it isn't easy to use as an aiming device (which is one thing I'm eager to try with the Navigator, since the screen would make it easy to get the camera into small places and not have to guess about where you're aiming). It's manually controlled, includes white balance control, external color filter. Many people have had no problems, but others have reported the housings cracking and becoming discolored/yellowed over time. For someone on a budget, I'd recommend this housing (there are cheaper ones, but not that I'd recommend -- I'd rather do without until I could afford one of the above, rather than save an extra $300-400 and get something not too useable due to very uneven balance and highly positive buoyancy that require additional weighting).
I should note that all of these housings have still photo modes which work as well underwater as you found it to work above water. They all also have moisture alarms, which is a must-have for an investment that in some cases costs about as much as the camera. All also have external microphone ports (passing sound through to the camera mic), which captures what sound there is underwater (mostly bubbles, but can also pick up the crunching sound of parrot fish eating coral very nicely, as well as my inadequate attempts at making whale sounds).

Subject: Light&Motion Stingray housing Date: Thu, 16 Sep 1999 10:07:36 -0500 From: "Ellis, Mike" (Mike.Ellis at COMPAQ com) I have been using the 900 in a Light &Motion Stingray housing with the Sunray Pro HID lighting system. I've made about 35 dives with it so far. The housing is well made with good optics. The monitor back shows all of the info you might have on your LCD (e.g. battery, tape remaining, zebra bars, etc.) The HID lights are nothing short of incredible. Several people who shoot a lot of video and/or see a lot of underwater video have commented on the vividness of the colors (particularly sponges.) The lights are actually bright enough to do day time fill lighting giving you the light intensity and range that still photographers get with a good high powered strobe. Dual batteries on each light give you 90 minutes total burn time using both lights. The flex arms allow you to position the lights to optimize the exposure of the subject. The lights take 30-60 seconds to come up to full power but I never found that to be a huge problem. I probably missed a few shots but the light I got on all the others seems to erase any bad memories of the ones that got away. Physically the housing, lights, and batteries are big and heavy. They create a lot of drag underwater. You arms will get sore trying to hold the housing up to look through the viewfinder (another story) or at the monitor back. I carry a housing in my right hand and was too frequently hitting the record button by accident and ran out of tape once. I guess I need to change hands. The housing is their generic housing so it doesn't take any particular advantage of the TRV900's capabilities. You are pretty much stuck with full auto mode or presetting a manual mode before you go in the water. The quality of the images speaks a lot for the 900's auto mode. Dealing with L&M was a bit confusing. I kept getting different answers about what the housing would and would not do depending upon who I talked to. I specifically told them I wanted to be able to control white balance and was told that the housing would do that. When I received the housing and found out that it didn't I was told that the TRV900 doesn't have white balance control via LANC. The biggest disappointment I find is dealing with L&M. The BlueFin looks pretty interesting. I really would like to have manual control of the camera underwater. I might upgrade my system but I would have to see it first hand and check it out personally before I bought it. Overall, I have been very satisfied. I know I made the right decision with the TRV900 and the housing and lights have allowed the camera to do it's thing. I looked at all of the other TRV900 housings at SEASPACE last May and didn't see anything that made me regret my decision. I shot a Hi8 TR81 in an Amphibico housing before this one. Amphibico makes some good gear. So do a lot of other folks.
Subject: Underwater Photos with TRV900 Date: Thu, 14 Oct 1999 10:13:19 -0700 (PDT) From: Bruce Sinclair (bruce.sinclair at att net) I want to thank you for the time and energy you have put into your site. The information on your site helped convince me to buy a Sony TRV900 camcorder. I have been shooting U/W videos with a Sony TR-101 Hi 8mm camcorder for years with good success. I realized that as my editing skills and equipment improved, I was being limited by the generation losses in analog 8mm and SVHS formats. So I decided to go to a digital format. I was very close to buying a Sony V1000 digital camcorder but the expense of an additional $2,600 for good U/W housing caused me some concern. I stumbled onto your site and after reading your comments and some of the contributors, especially their photos, I was convinced that the TRV900 was the correct digital camcorder for me. I purchased it ($2,090) and a new U/W housing from Light & Motion ($1,400 with trade in of my old housing). I have used the TRV900 on two dive trips with excellent results. I have learned to make digital stills from the 7 hours of U/W video I shot and send the digital stills to my new dive friends I met on the dive trips. My diving friends and I are amazed at how clear the digital photos are. I have included two examples in this email to you. The stills were loaded onto a CompactFlash disk from Simple Technologies (which I learned about on your site). I load the raw jpeg files onto my laptop and use the ThumbsPlus program (which I learned about on your site) to auto correct the images and crop them down. One image is of a red seahorse and the other image is of a pair of reef butterfly fish. I will send information in a longer post about using the TRV900 in the L&M housing for that section of your site.Images: seahorse, butterfly fish
Subject: RE: Underwater with trv900 (Navigator) From: "RICHELSEN,KAI (A-Germany,ex1)" (kai_richelsen agilent com) Assuming that you are using a NP750 or NP950 battery and no external lightning system the Navigator will have a negative boyancy of appox. one pound in sea water. According to my experiance the camera handling is still good. Here comes my unsorted top ten list of "Oh shit!" experiances with the Navigator: 1) LCD screen not folded to reverse position => no LCD monitor during the dive (But in bright sunlight you won't see much anyway :-)) 2) viewfinder not extended or locking clip not inserted => tiny viewfinder image 3) focus not switched to manual => camera focuses on every small particle in front of the lens 3a) camera set to manual focus, but FOCUS button not pressed 4) mic control set to AUTO => The camera gains the mic amplifier to the maximum while there is no ambient sound and your audiance will loose their ears from the whining of the capstan. 5) air bubbles on the lens of color correction filter => check the lens under water, wipe with your finger of necessary 6) no color correction filter in place => no vivid colors The filters are 10ft for the flip filter and 30ft for the external filter. 10ft means when the light travels 10ft through the water the colors will appear natural. If you shoot closeups of e.g. anemone fish at a depth of 10ft the filter is great. If you shoot fish at the same depth but 20ft away the light path is 30ft! Use the ext. filter. 7) set the camera to manual exposure but forgot to white balance => Auto white balance works fine as long as you don't mix daylight and lamps. 8) filming against the surface without manual aperture correction => underexposed subject (NO backlight button on the Navigator...) 9) hurried into the water without checking for housing tightness => I was lucky (until now). The housing was always thight... 10) equipment not leashed to the BC while proparing to submerge => once I lost my filter... -----Original Message----- Sent: Monday, March 20, 2000 11:38 PM Subject: Re: [TRV900] Underwater with trv900 From: "Tom Hardwick" (TomH at rdwick freeserve co uk) > I have recently bought a trv900 with an Amphibico nav 900 housing. > Any tips on camera settings would be a great help. ie shutter speed, > white ballance with or without filters on,white balance underwater or > on boat etc. Best tip I can give you is to test the boyancy in your bath. Add weights to make the combo neutral in whatever water you plan to dive, as the saltier the water the more boyant. Next I'd say go for a good powerful wideangle as the refractive index of water : air is quite different than air : air, and all lenses are telephoto-d under water. As everything you shoot will be hand held (untill you let go the combo - whoops - ) the wider angles diminish the camera shake. tom.
Thought you might like to view the still photos I saved from footage I shot with my TRV900 while scuba diving. I housed the camera in a Lights & Motion Stingray II housing. I have their Elite lights (used on the octopus sequence). I used Sony Master DV (DVM60M2) tapes. I shot in normal video mode and then captured the stills I wanted with the floppy disk adapter (superfine image quality) . I wish my housing had the capability of turning progressive scan on and off while in the water. I may upgrade to the LMI Bluefin some day, which does.
The octopus video footage is currently being reviewed by RealTV for airing. I'll let the list know if it makes it to the broadcast stage. Click here to see the photos: members.home.net/spantano1/

Subject: TRV900/PD100 rain cover From: Carroll Lam (cassie at dakotacom net) Date: Thursday, June 8 2000I ran onto a new rain cover at NAB this year that some of you might find useful.
It is made by ScubaCam Ltd in Australia (http://www.reefexplorers.com/) and carried in the USA by Band Pro Film/Video (http://www.bandpro.com/ - 818/841-9655). It costs $105 at Band Pro. Stock #SC/PD100 RN.
It is made of translucent vinyl except for a couple of clear vinyl windows for the flip-out viewfinder and the side button panel. It uses both drawstrings and velcro to keep in place along with some access sleeves for camera control. You can use either the internal viewfinder or flip-out screen. I haven't use the "Rainslicker" by Portabrace, but I've seen some reports that it's is somewhat of a nag to install. This cover installs very easily. The front lens "tube" is long enough and large enough to handle my Century 2X tele-extender and/or a lens hood. I had to add a piece of adhesive "female" velcro to it to get closure with no accessory lens or hood on my PD100.
There are apparently similar raincovers for the VX1000 and some betacams.
I have no association with either company except as a satisfied user.
Subject:[TRV900] Re: Rain/dust Covers for 900 Date: Thu, 21 Sep 2000 19:39:46 -0000 From: "Sandy Santra" (santra at mindspring com) --- In TRV900@egroups.com, "Guido Votano"I have the rainslicker. I have used it, but only to test it; in the middle of a downpour, it kept the camera completely dry, while allowing access to almost all controls. It's water-tight and well-designed. It does NOT work very well, however (water on lens), if you have a wide-angle lens attached (particularly one without a lens hood).
wrote: > Is there any TRV900 user who has used the PortaBrace Rain slicker for the > 900? Is it worth the huge price? Is it working with a BeachTek xlr adaptor > mounted?
Is it worth the price? Well, if you're going to be shooting in the rain.
However, there is a BIGGER rain hood that some people are buying. That's worth looking at. It solves the wide angle lens issue, for one.
I doubt the 900 rainslicker would work with the BeachTek XLR adaptor. The 900 rainslicker fits very tightly, particularly on the bottom.
FWIW, I have THREE Portabrace products now (in addition to the rainslicker, the 900 bag, and the hip pack for camcorders). I think they are EXCELLENT products. Cannot recommend them highly enough. VERY well-designed. Many "hidden" design features (subtle ones) you may not notice in the store, but after you've purchased one and used it a while, you'll start to be amazed by how well these products are designed.
I recently bought a TRV900 after reading your site, primarily for underwater use. The housings seemed too expensive, and I bought a used Light & Motion Seahawk TR housing with Lights for $650 U.S. This housing was made for the Hi-8 models, but I found, with a few well placed drill holes, it can easily be converted for the TRV900, saving significant dough for those diving trips! The front panel with the lens (bottom left corner) is attached to the housing by two bolts on a flange that is external and does not interfere with the seal at all. All you have to do is unscrew the bolts, cut the microphone wire (and rewire it later), rotate the faceplate until the lens is in the top center, and drill new holes in the flange (very carefully!). Once replaced, the camera has to be raised up a little bit to see through the lens with no obstructions, and the really close zooms won't focus properly (although I think that may be fixable), but other than that it works very well. All the controllers work except for white balance, which supposedly isn't controllable through LANC on a TRV900 and focus, but again, I think that may be fixable. I haven't actually used the camera in the housing yet, taking the empty housing for a few test dives to make sure I made no stupid errors, but - so far - everything seems great - all for $650 (with lights) and a couple hours of modifications.
Just an update on the modified SeaHawk housing I've been using with my TRV900. Everything is working well and I haven't had any leaks yet (knock on wood), despite probably 10 or 15 dives with the maximum depth I've taken it to around 230 feet. The halogen lights don't work too well at that depth, but the housing has been stellar. The only problem is the microphone cuts out after 190 feet for some reason.
I've since realized that you don't need to cut the microphone cable, just unscrew the electronic control board and pull out the mic wire. Then you can rotate the faceplate, drill the new holes, and presto. One caution, the switches on the side of the housing use magnets, so the control board needs to be put back in the exact same place. It's not too difficult with some trial and error.
Have fun, and if anyone wants some pics or advice, feel free to email me at (aldengreenhouse at hotmail com).
We (www.scret.org) use the TRV900 exclusively for underwater video - but we were presented with a unique problem - all of the housing on the market fail between 200-250 feet of depth, and we have some wrecks down to 350. Halcyon Manufacturing makes a housing that goes much deeper, and might be of interest to your web visitors: www.halcyon.net/lights/vidhouse.shtml. It's a very simple design that is rugged and can take any depth you might ever go on scuba.
Hi John, thanks for the excellent work on your site. My Sony trv310 digital 8 video appears to be falling apart so I'm thinking about upgrading. I've been using a Gates Catalina model housing with the wide angle port for U/W work, mostly shooting action oriented dives like spear fishing off the Gulf Coast of Alabama, and have been mostly satisfied. My main problems with my current housing have been:
1. You cannot see the manual controls as they interact with the camera, except for the power switch. As long as you set the focus on manual and don't' inadvertently turn it back to auto (which would be much more unlikely if you could see the control interface through a view window and, if it did occur or if you had forgotten, could be undone) that's not so bad.
2. With the Catalina housing, you can't use the still feature of the camera. there's no control for it. From your site I can tell that this won't be a problem with the Gates housing for the trv900. Otherwise I've been pretty happy with the Gates housing, which I purchased from camera tech.
