Zum - I didn't try to fish it yet. I was more interested in finding docks with brush underneath them at the time, but now I have this marked so I can return to it later.
lck.... - I did the measurement tool and it came out to about 20 feet long.
I think next time I'm on the lake, I'll adjust the contrast to get a really clear picture of it. Right now I had the contrast up on the machine to help see fish. You can get some nice pictures with contrast set to 'off'.
BTW, I found a number of docks with brush around them. Also found one set of weeds in a mostly barren area. Wouldn't have noticed them there without the sidefinder. I motored over there and shad were everywhere! I'd definitly be back to my 'hotspots' next week for a tourney!
