I seen those earlier this fall and though what a good idea to get people into a underwater camera for a reasonable price. I haven't heard of anyone using one yet. I know that they are made by Nature Vision who makes the Aqua Vu line of underwater fish cameras.
Shop around a bit if your looking for a underwater fish camera. I ended up picking up a Aqua Vu SPC-80 Color camera offline a few weeks ago for $197.00 CDN shipped with a spare battery.
I tried it out on the weekend and love it. It works awesome.
