GPS units are handy navigation tools for outdoor enthusiasts. While they're a useful addition to any gear pack, they also have some drawbacks. Understand the pros and cons of hiking GPS devices, and tailor your purchase and use of them accordingly.
Pro: Location
GPS units provide you with a simple way of getting to your location. Establishing your coordinates with a GPS is simpler than trying to determine where you are with a map.
Pro: Navigation
GPS devices make navigation easier and provide a bearing and distance to a preset location. When using GPS-based maps, you can also see and navigate according to terrain features.
Pro: Functions
In addition to GPS navigation, many units include such functions as barometric altimeters, an electronic compass, and time and date, allowing you to roll several devices into one.
Pro: Other Features
GPS can hold a variety of map data and routes, so that you have instant access to a lot of information. Some units include digital cameras and weather radios.
Con: System Issues
Since GPS devices rely on satellites, they are not perfectly suited to outdoor use. Interference from dense foliage, caves and deep slot canyons can cut communication off when you need it most.
Con: Reliability
Like any electronic device, GPS units are subject to failure from dead batteries. While you can limit the chances of this happening by carrying spare batteries, it is a concern.
