Underwater Pole Cameras

Hi everyone. I'm a fisheries biologist and I've been doing a lot of searching for a good underwater HD setup.

I originally bought an Olympus 1030SW but quickly found out the camera couldn't even record at 30 fps (xD cards are junk) and the video quality was very poor. Exposure/focus is locked to whatever you initially focus on. Not the best for fish that move.

A lot of the species I film are young and very timid and don't appreciate a person in a drysuit in the water trying to film them. I stuck my 1030SW on the end of a pole and the results were far better - but I couldn't see what the heck I was filming.

I figure an underwater camera with an external monitor/recorder is the best setup. I found this HD Pole Camera.

I also took at the Sanyo VPC-WH1 thinking that I could rotate the screen so it faced upwards. I still think I'd have a hard time seeing it through the water and it doesn't solve the problem of having to view fish from a distance.

Does anyone have experience with pole camera setups? Is there a camcorder out there that could accept input from the HD pole cam above? It would be great to have a dry camcorder and an underwater camera as well.

I know it's a bit beyond the realm of consumer video, but I thought I'd ask.
