Bell Cardinal Car Compass

This easy-to-read digital car compass utilizes the same patented sensor technology used by today's auto manufacturers. The simple calibration procedures allow this unit to compensate for your car's existing magnetic interferences. The Bell Digital Car Compass mounts to your windshield with a suction cup base, and features an adjustable bracket so you can set the unit at the perfect angle for your windshield's slope.

And both the backlight and the unit itself are protected with an auto shut-off feature to preserve your 2 "AAA" batteries. Requires 2 "AAA" batteries, not included.
