Well that sucks!
Sounds like operator error on some thing you don't know about as a new operator, or you just got a lemon electronic device.
Wish I could help you, I was looking forward to your reports!
It could have been operator error, there are minimal instructions that came with the unit, I youtubed different instructions and users to see what I was doing wrong but could not find anything I was not doing like they did, while I cant guarantee there were no fish in the area, I would bet a chunk of change that there were at least a few, and I do know there was a huge brush pile under it and could never get anything bu a clean flat bottom screen out of it, Im not sure what one would have to set on a fish finder to get it to acknowledge brush or some kind of obstruction.
