We have to thank the late and great Pres. Ronald Reagan for allowing those of us in the United States the chance to get our hands on what was previously reserved for military use only " global positioning systems. Reagan believed that it was safe for this sometimes sensitive technology to be released for public use and this action transformed our way of life. These days we use these systems in our personal and commercial lives and much of what we rely on, in turn relies upon this technology in one shape or form.
If you are an outdoorsmen, you will love the flexibility given to you by handheld GPS receivers. A long list of recreational activities can benefit from the technology. You may be a boater, fisherman, hunter, hiker, biker or enjoy the sport of geocaching -- either way you will be more productive and have more fun if you use one of these handheld units.
Whilst there are a number of companies that manufacture handheld GPS receivers, probably the best known and most highly respectful and on a worldwide basis is Garmin.
Handheld GPS receivers work by communicating with a series of satellites high above the earth. These satellites have been placed in what is called a low earth orbit, which means that they should always be accessible to your receiver, except in certain circumstances. For example, if you happen to find yourself in a densely forested area or in a steep walled canyon, the units may have temporary trouble.
The process of triangulation helps to determine your actual location to a very high degree of accuracy. Triangulation occurs when your handheld GPS receivers communicate with three different satellites and your position in relation to the three satellites can be determined.
If you are setting out on a hunting expedition you can use your handheld GPS device to determine the location of the best game and game trails. Imagine your sense of security and your air of optimism when you are sure about your location and pretty sure about how to find your targets! Some handheld GPS receivers are specifically designed for inland saltwater and freshwater fishermen and can come preloaded with the relevant data.
The sport of geocaching is becoming increasingly popular and there are handheld GPS receivers that cater specifically to you, if this is your passion. You can download GPX files directly from a computer into the database, or insert a tiny SD card in some cases.
Your trip into the unknown will likely take you far from any cell phone communication towers, but handheld GPS receivers do not require this technology and so long as you have a relatively open sky above you, you will always be able to relate your location. In this way it is very difficult to get lost and you'll have a good idea about the direction to take you back to civilization.
