These days, GPS receivers are common navigational add-ons in vehicles. But if you’re looking to utilize this cutting-edge satellite positioning technology out of the car—while geocaching, for instance—you’ll need a more compact, handheld unit.
The wide array of options may be intimidating, but it also gives you tremendous flexibility in selecting a receiver that fits your needs and budget.
Bare-bones units run for as little as $50 used. For higher rollers, more money can score you fancy graphics, bigger screens, more memory, preloaded map data, wireless capability, a stronger antenna, and waterproof certification.
