I have a Helix 10 SI GPS...moved it to the bow from console...
First, the depth in the readout box is different from the actual depth...ex:in 8' of water on sonar, but box may show 15'....doesn't do it every time when TM is deployed but most of the time...
Secondly, always shows a double bottom at the same time...
Thirdly, need to clean up some interference when ultrex is running... Power from unit is run straight to battery...ant ideas?
Have tried resetting defaults, but no help...
Thanks
Gary
