The Ewa-Marine TV-171 Waterproof Case is manufactured from double-laminated PVC and has an optical glass port. It is rated for dives of up to 32.8' depth, and it is fitted to match the JVC GY-HD100 and GY-HD101 camcorders. The TV-171 is perfect for snorkeling, shallow diving, high humidity, or generally foul weather conditions. It gives your JVC camcorder the best possible protection while being fully operable; all of the important settings, like the zoom, manual focus, white fader, iris, shutter, etc., are usable to the full depth rating.
A pair of noncorrosive and seawater-resistant clamping rails fit together for sealing, tightening by using the knurled thumbscrew knobs. The TV-171 can incorporate the optional BV2 lead weights to achieve ideal underwater buoyancy, and it is supplied with a black case with a waterproof interior and zippered side pocket.
The TV-171 housing is specifically designed to fit the aforementioned JVC units, but others may also fit.
