Handheld GPS
These units are small, lightweight, and portable, so you can take them virtually anywhere. They operate either on Alkaline or NiCad batteries with an average battery life of 12-24 hours of constant use. Most have 12-parallel channel receivers which lock onto satellites quickly and stay locked on in dense cover. Simple keystroke commands ease use and many are just as sophisticated as their fixed-mount counterparts. With built-in LCD displays for low power consumption and backlighting for use in bright and low-light conditions. Some units even accept an external antenna for better satellite reception.
A handheld GPS does some of the same things as a global positioning system that may be already installed in your vehicle. A handheld GPS is a device that tells you where in the world you are. Maps of roads or waterways or even parks can be downloaded into a handheld GPS, so that if you go hiking or boating you will always know where you are and how you can get to another location! A handheld GPS acts as a navigator that will keep you from getting lost, or will help you locate yourself if you find yourself in an unfamiliar place.
