FAQ — Navigation & Safety Gear

Do I still need a compass if I have a GPS device?

Absolutely. A compass requires no batteries, works in all weather conditions, and never loses signal. It serves as a critical backup when electronic devices fail. Every experienced hiker carries both a compass with a map and an electronic GPS. Learning basic compass navigation is an essential wilderness skill.

What is the most important safety item for solo hikers?

A personal locator beacon (PLB) or satellite messenger is the most critical safety item for solo hikers. It allows you to send your GPS coordinates to rescue services from anywhere on Earth, even without cell coverage. Combined with sharing your trip plan with someone at home, this provides a strong safety net.

How accurate are handheld GPS devices in the mountains?

Modern multi-band GPS devices achieve 1-3 meter accuracy in open terrain and 3-10 meters under tree canopy. In deep canyons or near cliff faces, accuracy may decrease to 15-30 meters. Multi-satellite systems (GPS + GLONASS + Galileo) significantly improve accuracy in challenging terrain compared to single-satellite units.

What is the three-blast whistle signal?

Three short blasts on a whistle is the internationally recognized distress signal. Repeat every minute and listen for responding signals. A quality safety whistle produces 100+ decibel sound that carries over a mile. Unlike shouting, whistle blasts require minimal energy and can be sustained for hours during rescue situations.

Should I buy a dedicated GPS or use my smartphone?

Dedicated GPS devices offer superior battery life (20+ hours vs 4-6 hours for phones), better durability, and more accurate positioning. Smartphones drain quickly with GPS active and can break easily. Use your phone as a backup with offline maps downloaded, but rely on a dedicated GPS as your primary navigation tool for serious outdoor activities.
