With its synchronized TrackBack feature, you can review sonar history and set waypoints of a previous course. Easily networks via ethernet with up to 3 HDS devices for side-view imaging. Find a spot, push a button, mark a waypoint; if you're networked, that waypoint is automatically shared with every HDS onboard.
