Most of the guys I know running a livescope fall into one of two categories. Either they would have caught a limit anyway, might have taken them a little longer but still would have, or category 2 unless there is a diver hooking fish into their hooks for them, they ain't gonna catch very many. Me I am lazy, and more importantly CHEAP, so I don't have anything more than a $100 unit. Heck often as not anymore if crappie fishing unless someone wants a mess to clean I am likely to throw them back, again the lazy part.
