798 si hd
« on: May 13, 2011, 07:11:29 PM »
I was curious if anyone knows why I'm not seeing my downrigger ball on my sonar in my home river, (St Lawrence) Upstate NY.  It showed the balls in a different body of water last week.

Blowback (I think that is the correct term) - the downrigger ball was aft of the sonar beam due to additional current or boat speed?
