What To Look For
As any hiker knows, getting lost is a potentially dangerous problem. A GPS unit can help get you out of a bad situation or keep you on track. Knowing what you need from a hiking GPS unit is the key to buying the right one. A good hiking GPS unit should be waterproof, lightweight, have a long battery life and a car recharging system. It also should have enough memory for several topographical maps, base map ability--so you can drive to the trail--and the ability to store notes.
Common Pitfalls
Perhaps the most common mistake people make is using trying to use an automobile GPS for hiking. While they are fine for driving to the trailhead, car units may not be much help off the road, although some of the newer hybrid models do work for the road and the trail.
Where To Buy
Hiking GPS units are a specialty item. You're most likely to find them at large sporting goods stores. Amazon.com and Buy.com also have large selections. If you are buying from an independent online seller, make sure the model is up to date and under warranty.
Cost
The cost of hiking GPS units can vary widely. Standard units usually run between $300 and $400; budget units are available for less than $150. Smaller watch-type units sell for about $300 and a geocaching (game of high-tech hide and seek) GPS usually will be priced between $500 and $600.
Comparison Shopping
As with most electronics, the more features and the more lightweight the unit, the more expensive it will be. Garmin has a large selection of mid-priced units. Magellan and and Navman both have highly-rated units at competitive prices.
Accessories
Additional topographical maps are a must-have accessory for the serious hiker. They save room in your pack and are more convenient than paper maps. Another essential is a car recharge. A car mounting unit will let you use your unit as a road GPS as well.
Insider Tips
A non-reflective screen is a real help in bright sunlight. A 12-channel receiver system will get you the best reception in a dense forest.
