Got one....had it for years, what do you want to know?
You need a Sony (or Panasonic if you have the adapter) with a LanC or Remote connector. Then everything works electronically through the right handle. You can zoom, white balance and record using the buttons. They weigh nothing in the water but are quite heavy on land.
I will reach across my desk and say.....a Sony HDR-UX7 fits!
Any Sony will fit and if it has a 'remote' connector you can control it using the external switches. I am not up on Sony camcorders now so I guess a Google may help if you need a more up to date camera than the above.
I have never had a manual for mine. Not needed one as they are fairly simple things. The housing does not have batteries or the like. You scew the camera onto a base plate using the tripod screw. The base plate clips into the front section of the housing, plug the mic and remote cable in, and then you push on the rear over the two O rings. Pull the side latches down and you are done.
The camera i flooded was a sony mini dvd, i just cruised ebay looking for digital videos with LANC. As for the housing, i rinsed it with fresh water and dried it, i now have to find another video camera to see if the housing works?
House insurance have paid up, and i have now bought a Fuji FX600 with housing, which does full HD video.
