We went out yesterday afternoon and my Hbird Helix 7 started acting up again. At the beginning of this year it was giving me some weird images and stronger images on one side vs the other in SI mode. That seemed to have cleared up and then last night It would not give a depth reading on any view or chart image. It was still giving SI or DI images and seemed to be tracking along but no depth. As the afternoon progressed the screen became increasingly pixelated. I know the battery is good and the connections are good, no corrosion or loose terminals. It is on and independent ground and the ground is good. I have to that this is the first HB product I have been a bit underwhelmed with. I strayed from HB once and got a Garmin chartplotter for out family boat many years back. It was a Garman 636 and I hated that unit. I found it to be very clunky and slow, kind of like the Ford Sync before they abandoned it. I am going to reach out to HB and see if they can offer some insight but I think a new unit is coming. My wife asked the other day "why doesn't our fish finder shoe the fish moving like that guys?" and I told her because he spent way more on his than I did lol. She then asked if one of those would help us catch more fish. I don't really need another rabbit hole lol. I do want opinions and testimonies of what you guys have and why you love it or hate it.
