I am thinking about getting an underwater camera to attach to the
downrigger ball. Aqua-vu seems like a decent choice (model SV or MC w/
120 ft cable). Does anyone have any experience trolling w/ this
system?
Is it a hassle to use? How do you like it? Any advice prior to
purchasing?

I will be used primarily to target salmon and walleye on the Great
Lakes.
