I have always wanted to use one, but I doubt I would see much in the Willie (except in the summer). Still, I am curious as to what is going on when I mark a bunch of sturgeon while sitting on anchor or catch a bunch when only marking a few. What are they doing, is there a difference between biters and non-biters?
I see vidoes of ice fisherman using them to actually see the bites, but I think that rather than using it for this that one could learn a lot about fish behavior with a camera. I think that is where the real benefit lay.
