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 for easy removal or a permanent screw-down base and standard lighter plug. The genuine PTC ceramic element generates 340 BTUs of heat to quickly defog your windshield. The Fairview is completely safe and is not hot to the touch. The small footprint heater takes up little space on the dash. Attached 5' power cord with standard 12V DC plug. 7"W x 4.5"H x 2.5"D.
