Post by: rnvinc on May 09, 2017, 10:19:47 PM: It may be an algae bloom ...and can be worse if the 83kHz beam is being used ...

Can you try the 200kHz Beam Frequency to see if there's any change ...??

Post by: kfield65 on May 10, 2017, 08:19:39 AM: I only use the 200hz. Water was clear down to 8+ft.Didnt see this last year don't know if when putting everything back in my boat from winter I may have picked up some ground problem. It is on the crank batt with the other accessories but didn't have it last year. Puzzling .Thanks for your input though keeps my mind working
