I couldn't figure mine out until I took my boat to the water and left my fishing poles at home. It took about 3 or 4 hours of playing with the settings and it all started making sense. When that happened, I wished I had my poles with me! Now I have 2 Humminbirds, 1 Lowrance and a XI5 trolling motor on my boat, and wouldn't go to the water with out any of them!!
