Hey Bob, understand the side from the tech's view. My problem is that I have gone through many many troubleshooting steps to eliminate possible environmental issues that could be causing the problem. Number 1, NO one has acknowledged these steps and Number 2, Humminbird has not even acknowledged receiving the pictures or video of the issue. I believe if the technician saw all the elimination steps and video, they would have to conclude the unit has a problem, EVEN if they cannot recreate the problem on their bench.
I have never raised an issue like this with a company before, maybe I'm getting old and tired of having to battle for service. I'm fairly tech savvy. Have run technical support centers both hands on and remote. I'm sure this unit has a problem. My only real step to take and PROVE it, will be to buy another Helix 5 and run it. I've thought about it but then where does the cost go? Hopefully Humminbird will determine there is an issue this time and repair or replace. I'm pretty happy with the performance (when it is working).
