Just dump it and leave(we'll call). Long short, we spent about 30 minutes in tackle shop and when we come out notice tech working on my boat. Check with him and he says he will be though in about 15 min. Replaced the lowrance advised and supplied head sensor and ghost worked again. Dropped it in water and ran it for 30 min. no problem. Fast forward to last Monday PM, check out excursion and ghost acts weirdly. Spot lock making big circles, randomly taking off on high speed in some direction other than prescribed, unable to steer in some direction (right or left), ect. Wow, what now? Well late yesterday I go back out to see if i could recalibrate things. I did a full factory reset, and recalibrated everything and it worked fine. Hopefullly end of my journey!
