I have been having issues with losing the bottom in around 110ft with my Lowrance HDS8. The screen scrambles and the depth goes to dashes. doesnt matter if moving or drifting. I have tried shallow water, deep water scroll speed normal, 2x and ever 4x. I have verified the number on the sonor and its correct. Im lost:angry: Has anyone else experienced this, if so please let me know what corrected your issue.
thanks
