I have one it came on my boat. I dont really like having another thing to think about or wonder if I have it set right but that said I have turned it on and seen fish come up off the bottom and come right up within a few feet of my tm and go back down on my sonar.

I have also turned it on and off a few times with a partner on lake fork in a draw small club tourney and we both saw it bring the bait fish right around our boat and then they would disperse when I turned it off.

I havent ever caught fish because of it that much I am sure but I also havent really messed with it much other than 3-4 times and two of them on different lakes are mentioned above.

..... bought one
...... sold one
