You've heard that new sport, geocaching, is fun. Or, you're tired of getting lost on your travels. Welcome to 21st century. Global Postioning System (GPS) has been around long enough that prices are reasonable and technology is user-friendly. With myriad brands and models, how to choose?If you want a GPS for both hiking and driving use, then a handheld unit would be way to go. Some handhelds even have accessories to allow them to be installed in an automobile. But don't rule out a PDA. More on that in a moment. For driving only, there are GPS receivers made just for vehicle use.
Handheld GPS receivers are either mapping or non--mapping. A basic, non--mapping unit can often cost less than $100 US and usually has/displays following:
- Location
- Compass heading
- Elevation above sea level
- Accurate time
- Satellite location and signal strength
- The ability to calculate distance traveled
- The ability to record your path as a set of waypoints
- The ability to navigate routes
- The ability to retrace your steps
Handheld mapping receivers do all above plus have ability to display maps. The maps are either pre--loaded or uploaded from your PC. Prices are reasonable for mapping units, starting at around $150 US.
Paper maps are strongly recommended whether you're using a mapping receiver or not. Paper maps do not require batteries and probably won't go defective. Also, a paper map gives you a "big picture" view of your situation -- something lacking on small screen of a GPS.
I mentioned earlier your considering a PDA with GPS capability. A PDA is bulkier and battery life is usually shorter, but if you're using a PDA anyway, then there are several ways to turn a PDA into a GPS. Some PDAs accept a GPS "sleeve." That is a device that PDA nestles into. Another choice is one of Garmin's PDAs. Garmin is probably most popular GPS maker and they have one PDA/GPS that is Palm--based and one that is Pocket PC--based.
