Finally, there’s a global positioning system receiver with a bright, full-color screen and an affordable price tag. Magellan’s new eXplorist 110 ($130, magellangps.com) has everything you need to stay on track while outdoors, whether you’re tackling the backcountry trails at Philmont Scout Ranch or seeking the largest geocaches in your neighborhood. The unit will run for 18 hours on two AA batteries. Remember, though. No technology, no matter how excellent, can replace a good ol’ Scout compass and map — and the skills to use them.
