Thread: Helix Mega Sensitivity

Unfortunately, after my 2nd trip with my Helix 10 G2N, it wouldn’t power back up and it had to be sent in for service. They put a new board in it and updated the software to the lastest version. I don’t have a lot of time with this unit, but it seams different since I got it back. If I switch side imaging frequencies from the 400 htz range to the 800 htz range, it’s very hot, so I have to turn the sensitivity down quite a bit. If I go from 800 to mega, I have to turn the sensitivity up to 20 most of the time in 30’ fow. In 30-40 fow, the highest sensitivity still seems weak. Is that normal? In my first 2 trips, I don’t remember having to turn it up that high. I’m comparing it in the same part of the lake.
