got one of these units on a boat i bought. display was inoperative so had it fixed by a local tech. got it back last weekend.
it worked fine at the dock as a sounder and got a gps fix too. next day on the lake, the sounder started going crazy. when started up, it would function in automatic for less than a minute OK, then the auto ranging would go crazy in that it would start going to deeper depths without the boat going anywhere!
this would continue until it was showing a max range of 1500+'. obviously, on that large a scale you couldn't see any detail at 30'. trying to take manual control of it, it failed to operate after reducin the scale to 40 to 60' depths - no longer showed bottom or detail.
i know i'll pull it out and take it back to the tech. any suggestions of what part is failing?
