Suunto MCB

Marine adventurers who need a sighting compass choose the Suunto MCB Compass. The Suunto MCB floats and features a mirror that locks at set angles of 60, 120, and 180 degrees. Mirror compasses allow you to view the compass dial and background at the same time. Plus, the vertical line at the center of the mirror can be conceptually extended to the horizon, which helps you to more accurately target bearings. Use the attached whistle for signaling.

When taking readings, the notched rotating bezel turns easily and in 2 degree increments. The clear plastic base allows you to see maps and charts beneath the compass. The map scale displays in inches and millimeters.

The Suunto MCA Compass uses a Two Zone System to achieve precise measurement. Back in the day, users had to purchase a compass balanced for one of 5 different zones. A Suunto compass is balanced based on only the northern and southern hemispheres. This means that Suunto compasses balanced for the northern hemisphere also provide accurate readings in many northern parts of the southern hemisphere. The Suunto MCA is designed for the northern hemisphere. If you are traveling very far south into the southern hemisphere, you may want to look for a Suunto compass balanced to that location.

Comparison: More of a dry land adventurer? The Suunto MCA features the accuracy of the Suunto MCB, but forgoes the MCB's floating capabilities and whistle.
