Compare GPS navigation systems before you buy

Not all GPS devices are the same. Consider power, signal strength, visual displays, features and cost when shopping for a GPS system.

I recommend: Check out the variety of GPS equipment from major manufacturers, including Garmin, Magellan, Leica and Trimble.

GPS devices can be used in automobiles, boats and airplanes

If your vehicle, boat or airplane doesn't come automatically equipped with a GPS system, you can invest in portable GPS systems that work from any vehicle.

I recommend: MyPilotStore.com has a variety of portable GPS navigation systems and GPS trackers that send out a signal of your location in the case of an emergency.
