HDS 10 on the front....the graph is reading properly everything going great. Only problem is the digital depth on the graph doesn't display. The graph is reading properly just not displaying the depth in the corner it's blank. Any ideas? Transducer is inside the trolling motor so I'm a little worried about taking that thing apart. I'm about as handy as 1 legged man in a butt kicking contest. LolĀ
