Title: Dual returns and double depth in 7-12 FOW
Post by: hollada on May 20, 2016, 06:23:09 PM

Had a strange issue today where I was getting dual returns on the screen - almost like a split sonar within the same view on my 959. The depth was reading twice what my 1199 at the console was reading. Tried rebooting and that didn't help.

Using the US2 transducer built into the fortrex TM. Boat and equipment is a 2015.

Any suggestions?

Two suspects.
    1st is sensitivity may have been to high. Doesn't take much in that shallow of water.
    2nd is if both units were running at the same time, this can happen. (cross talk). Try turning the 1199 off.
