The Vineyard Coast Guard Auxiliary will offer a two-week GPS course for mariners this month. The course will meet on Feb. 11 and Feb. 18 (both Wednesdays) from 6 to 8 p.m. at the Martha’s Vineyard Regional High School.

The course focuses on GPS equipment typically owned by recreational boaters. Course participants who already own hand-held GPS units are invited to bring them to the class. GPS units will be available for those who do not own one.

Pre-registration is required. Instruction is free, but there is a $40 fee to cover the cost of textbook, charts and materials. For information and to register, call Chris Scott at 774-930-0921.
