Brunton Signal Whistle Compass

The Brunton MM10602 functions as a digital map measurer, calculator, miniflashlight, key ring, and compass--all packed into one device. This compact tool, perfect for hikes and bicycle trips, allows you to enter the scale of the map you are using to accurately measure distances from one point to another. Enter the scale using the unit's number pad and compute with the scale and measure buttons.
