Title: Sonar picture looks digital
Post by: Dlc1978 on March 10, 2017, 09:56:02 PM

Last year my sonar image got very blocky, or digital looking.  I updated it and it didn't help.  Seems to be much worse in shallow water under 15 foot.  And suggestions on what it might be or settings I should try?

Some of the core SI units had some 2D problems when running both the 200 and 83 Khz 2D.  Try turning on jigging mode and see if it helps.

It would also be a good idea to install software version 7.670

Ok I haven't really used the jigging mode but I will tomorrow.  Thank you.
