Power Source

Power Source

Two triple-A batteries provide as much as 15 hours of use. The are not included in the purchase. The use of regular triple-A batteries is a great feature. It is a lifesaver when batteries cannot be recharged for a while.

Many systems have rechargeable internal batteries. They provide more battery life but can’t be swapped if they die. With Foretrex, toss two more triple-As in, and the GPS is back and running.

Durability

Durability

Bottom Line

Bottom Line

This device is a bit unusual. It is not a full-fledged sports watch. The GPS does not have the feature set of nicer handheld receivers. It is best suited for people who want to minimize backcountry gear weight and have the device conveniently available.

The inability to add detailed maps to the unit is among the most significant functions sacrificed. It is intended to be a basic GPS unit. There is no electronic mapping. It is marketed for tactical paramilitary use where the user carries a GPS only as a navigational aid rather than a navigation solution.

The Foretrex 401 meets the requirements of a great unit. The Foretrex 401 model has a barometric altimeter, an electronic compass a rugged waterproof body, and a GPS receiver that is highly sensitive. There are some issues getting data off the unit that may cause a few problems. A tester rated the Garmin Foretrex 401 as nine out of ten for accuracy, 9.5 for durability, seven for battery life, and 8.5 for ease of use.
