I tried searching but don’t see any of the same issue I’m hoping to fix. My friend has a helix 10 mega DI g2n with the ultrex that has the mega di transducer built in. He’s having issues where the sonar will somewhat randomly read well over 1000 feet of water. Sometimes it goes away in a few minutes and other times it takes quite a long time. He has updated the software to the latest version and the issue persists. Any ideas? TIA
