Lowrance Sonar Trouble

[CronkHunter]

My 102c does not read depth or show anything when I am going faster than trolling speed. The screen gets a bunch of interference and the depth just flashes. I would like to be able to go over a spot at 5-10 mph and check to see if there are fish but I have to go real slow to get a reading. Any suggestions?

Sounds like you are having a turbulance issue since it only happens when you are picking up speed. You will need to move/adjust the angle of your transducer. Also have your ping speed set at 100%, this will give you a faster return.
