With the sonar capabilities of the Garmin units getting all the attention I must confess one of my favorite features on my Garmin GPSMAP units has nothing at all to do with sonar – Auto Guidance 2.0.
I find Auto Guidance 2.0 incredibly useful because it makes sense of complex navigation paths. Where other GPS products will create a straight-line path from Point A to Point B that will often cross dry land or other hazards, Auto Guidance 2.0 utilizes detailed GPS maps to create a path to your intended destination that takes into account shallow water areas, hazards, islands, etc. GPS Navigation for the angler has never been easier or more useful!
