A PAIR of Garmin GPSMAP 7612XSV 12" Multi-Touch Chartplotter is a great addition to any boat's navigation and control system. With its easy-to-use interface and advanced features, you can easily navigate through the water, see radar, sonar, engine readings, media control and more. The device is designed for use on all types of watercraft, and its multi-touch technology allows for quick and easy chart plotting. Having a pair gives you multiple screens at one time. Garmin, is known for producing high-quality navigation devices, and these are no exception. It is perfect for those who want a reliable and easy-to-use chartplotter with amazing features.  I am only selling these because I upgraded my boat.  They are both in perfect working order.
