The problems that I am having is Target separation. There doesn’t seem to be any, and most of the time I literally cannot see my jig I mess with the gain, I manually set depth everywhere I go. It seems like the depth bounces between the actual depth and some other random depth it decides to display. It seems like a great unit however it just doesn’t seem to be a consistent user experience. The GPS is nice you are right. That seems to work all the time no problems. I’m not giving up yet on it I’m just not extremely impressed with some of the bugs in the software.
