Thread: Helix 10 Mega Gen 2 images showing wrong depth

On my Helix Mega 9, upon this posting, One time, I had a issue with the unit showing double the depth and it was in muddy water and it was in 16 ft of water showing 35-40 ft deep of which was the wrong depth. . This morning in heavily stained to light muddy water, the Helix Mega 9 went crazy while I was in 10 to 15’ of water, and the depth would show 300’ to alittle over 2000’ ft of depth. In a spilt screen mode, The SI was set to 60’ on the side view and it was on the top with my DI on the bottom showing the deep depth settings and no pic of the bottom, but the SI was showing normal on the top half of the screen. I reset the unit 4 times over a couple of hours of trying different settings hitting default setting each time and completely resetting all the settings each time, and back to 200 to 2000’ it would show again. In sonar mode, it would show the depth say at 2000 ft and all verticals lines of dots but no bottom or any fish or anything. I turned off my other 2 depth finders thinking maybe they were somehow interphasing or something. That didn’t effect anything. I would shut it down and unplug the depth finder, wait 5 minutes, plug power chords back in and turn it on, and it would start up in the deep depth modes sitting in 10’ of water and finally on the 5th resetting of the depth to finder back to its default setting, it worked perfectly showing the right depth as I reset all my personal settings and ran it for over 45 minutes as perfectly as you would want it to work. Any comments would be appreciated as I plan on eventually calling Hummingbird to ask what the heck is going on. I bought this Helix Mega 9 last August and haven’t had any real issues with it showing the wrong depth till about a month ago for the first time till this crap this morning happening. Very frustrating to say the least.
