Mariner's Compass

The marine compass is still the boaters primary navigation tool, and an essential tool when all else fails.  This guide explains how to select, install, calibrate and use your compass on board your boat.  You will learn which features are most important and what will work best for you, how to deal with variation between true and magnetic north, and how to adjust your compass to remove most of the deviation caused by local magnetic influences.  This is an essential guide for all boaters.

USPS Guides are available to members and the public at various marine supply stores, and also directly from United States Power Squadrons Headquarters by calling 1-888-FOR-USPS between 8:00AM and 4:30PM ET Monday through Friday, or on-line via the United States Power Squadrons Ship's Store.  Visa, MasterCard, Discover, and American Express are accepted.  These guides are also available to USPS members through their Squadron Educational Officer.
