Pres. Ronald Reagan believed that the technology previously thought to be too sensitive and classified would be of great help to the general public in the United States, when he sanctioned the use of global positioning systems back in the 70s. Previously used only by the military, Reagan believed quite rightly that the public would benefit from its use. In turn, this action helped to transform our way of life and it is difficult to imagine where we would be in our personal and business activities otherwise.
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.
Garmin is probably the most well known and widely respected manufacturer of handheld GPS receivers in the world. A number of different manufacturers offer models for specific needs.
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.
A process of triangulation occurs when three different satellites are able to communicate with your handheld GPS receivers. This process enables your location to be specified with a relatively high degree of accuracy.
Handheld GPS receivers can be particularly useful if you are a hiker. Imagine the ability to locate and narrow in on the best game and game trails. You should be pretty optimistic about how to find your targets and have a productive day. For inland salt water or freshwater fishermen, some units are available preloaded with relevant data.
If you like the sport of geocaching, you really should get one of the handheld GPS receivers that are specifically designed for you. You will be able to download GPX files directly from your computer or by installing a tiny SD card.
if you’re heading out into the unknown you will likely be very far away from the nearest cell communication tower. With handheld GPS receivers you do not have to worry about cell technology, as if you have an open sky above you, you will be able to relate your location. Have fun on your day out without the worry about getting lost, knowing that you will have a good idea how to get back to civilization.
