I run a garmin 162 on nearest with my 997 on side scan, do not care if the HB gps is not great, it works good enough to find my bass holes but running the garmin with the side scan can you make sure you do not go over some places you all ready have found. Side scan is what it is all about. Finding new beds, after I locate them I use my under water camera to see what is down there before I make a new way point. You can see what the sturctue is and see fish//
