Helix 7 Depth problem

[Justbass11]

Ok, I was able to download the new software for my Helix 7 DI GPS. The problem is I could be in 20 to 30 feet of water and it will show that I am in 1ft of water. Or I could be running in the middle of the lake and be in 68ft deep water and it will show the correct depth but then it will jump to 2ft when I’m still in 68ft.  The graphics are good and I don’t have a problem with anything else. I hope that I explain this good enough, any suggestions would be appreciated.

If this is happening only at speed then your transducer location/attitude needs to be tuned.

Losing signal usually indicates a transducer problem, contact Hummingbird.

Need to know if only at speed or all the time.  Two different scenarios which could have two different solutions.  Not enough info to contact Humminbird.  If only at speed all parts and connections could be perfect and there still could be a problem with locating/tuning the transducer position/attitude.  If this is the case Humminbird can do nothing.
