Boaters can defog their windshield in just minutes using the Fairview 12 Volt defogger. It is easy to install with either a sure grip suction cup enabling the defogger to be easily removed and stowed when not in use or a permanent screw-down base and a standard lighter plug. Its genuine PTC ceramic element generates 340 BTU's of heat to quickly defog your windshield. Fairview is warm but never hot to the touch. This small footprint heater takes up little space on the dash.
