Ideal for Sailors who are learning to Navigate with Charts.
Includes corrections for : Variation, Annual Magnetic Variation Drift, a boat's Deviation, Set and Drift factors.
Simple to use: Input values form the your nearest Chart's Compass Rose: including Variation and Annual Increase. Along with your boat Compass's Deviation.
The Calculator will instantly correct between any: True, Magnetic and Compass bearings.
