Hiking and Adventure Guide to the Sonoma Coast and Russian River
Author and photographer Stephen W. Hinch has taught courses in GPS navigation to police and fire personnel, park rangers, search-and-rescue staff, and recreational outdoor enthusiasts since 1998. His experiences as a GPS instructor have shown that many of the most common classroom questions about GPS aren't adequately explained either in GPS instruction manuals or existing guidebooks. Trained as an electrical engineer, he has over 25 years of management experience in the high-technology industry.
