The Ewa-Marine TV-170 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 is fitted to match the JVC GY-DV500 and GY-DV700 as well as the Sony DSR-250 camcorders. The TV-170 is perfect for snorkeling, shallow diving, high humidity, or generally foul weather conditions. It gives your camcorder the best possible protection while being fully operable. All 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-170 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-170 housing is specifically designed to fit the aforementioned JVC and Sony camcorders, but others may also fit.
