Thanks supercat

Thanks Netguy. I really like this unit and it’sa relief to know I don’t need repairs. Fish on!

Thanks. I thought the way you test your depth Finder was to hold it over a hard surface and it should read the correct depth? Not sure if that’s correct. When I hold it at 5’ above the hardwood floor it was reading close to 20’? Just doesn’t seem right. Thanks again.
