I have a Lowrance GlobalNav 200 that i am looking to trade for another GPS unit. This unit is very clean, but does have some minor scratches from use. Satellite reception is surprisingly good, i even picked up a few in the house. Features include: Rockwell 12 parallel channel receiver, Detailed plotter, TrailGuide steer screen and many more. This unit is also waterproof! Unit comes with: Original box, 12 volt car charger, original instruction manual, and wrist strap. Your unit must work and provide fairly accurate satellite reception. I would really like a Garmin Geko, but i just want to see what's out there.
