Types of Hand Held GPS Devices
Handheld GPS devices can be classified into two types. One type is a dedicated GPS receiver. This device can show you where you are, the direction you are traveling, how long it will take to reach your destination, etc. The Magellan Triton is a good example of this type of hand held device.
The other type of hand held GPS device is an add-on that is attached to a PDA. When plugged to a PDA, it allows the PDA to function as a GPS. This type of device can be bulky and inconvenient for most people.
Getting a Satellite Signal
If you are thinking of buying a hand held GPS, you must consider where and how you intend to use it. Keep in mind that getting a signal from a satellite is dependent on line of sight. If you will be using the device in mountainous areas, deep canyons, dense forests or even skyscrapers in a city, you may not be able to get a good signal. Normally there are enough satellites overhead but it is always best to keep this possibility in mind.
