This handy 12V heater will bring a little comfort and convenience to early/late season boaters. Place the heater on the sole, dash or counter for instant warmth during cold weather. You can even place it under a hatch, window or windshield for rapid defrosting. The 3-position switch allows the unit to remain off when not in use, serve as a heater or just as a fan. The long, 7'' power cord plugs into any cigarette lighter style 12V outlet on your boat or in your vehicle.
