I got to play with one the first time the other day and sure enough I saw a crappie and swam my jig over to it and KABOOM it hit my jig .
beyond that I also liked the fact I could see what the fish were doing in relation to the jig and some fish were quite bashful and would retreat back into a pile of brush when the jig got close to them .
and of course it also surprised me to see how fast the fish were moving down there in cold water as the went about whatever it was they were doing and that part I never did really figure out . interesting equipment for sure and to be sure lots of times it showed a herd of fish and we never got a peck from them as they sat in brush like Christmas tree ornaments .
I am sure it will help some folks ketch fish and not so much some others and to be sure it could cause one to be so distracted they don't ketch fish as well ...
