I have a 24 volt motor guide varible speed trolling motor. If it were only as simple as another unit turned on or just a trolling motor button. This unit's digital depth goes haywire with nothing else on and not using the trolling motor. Just a change of depth sometimes causes the units digital depth to start panicking and go from 1 to 600 feet. I first used this in truman lake and for a period the depth would read 5 feet deeper than it was constantly. I turned my lowerance off to see if it could be corrected and that did not work.
I read this forum daily and tried many if not every setting the unit has and became very frustrated.
The last straw was on monday. I was fishing in 8-9 feet of water (constant). Nothing else on my boat was running. did not use the trolling motor (drifting with the wind). was in factory settings and the digital depth went from 1.5 to 900 feet and everthing in between. Rebooted twice. Same results. At that point I suspected an evil spirit had taken up residence behind the donut of my humminbird. Called humminbird and they told me to send in everything including the tranducer. Hope it gets fixed. Am lost without a trolling motor up front when crappie fishing. Funny I never had this much trouble with all of the other lowerance units i have had. If the lowerance causes the humminbird to have problems, why doesn't the humminbird cause the lowerance to have problems?
