Got Kelly a aqua-vu for christmas and we love it, it doesn't spook the fish at all. Even had a jack try to take it. We drill 3 holes put the camera in the middle and then watch on of the hooks. You can see fish for quite some way and then see them more in detail when they do get closer. It never bugged the whites, perch or jacks that we have seen yet, and kelly is always spinning it around looking for other fish.
I like the camera, ours has led lights so you can use it at a lake as deep as burntstick, in the summer and can even troll with it.
