Engadget giveaway: Win a pair of GoTenna off-the-grid communicators!

No cell service? No problem.

Camping and hiking trips can be doubly relaxing since you're often left without cell service and have no choice but to enjoy nature undistracted. If you get separated from fellow travelers and need to communicate, though, having a tool like GoTenna can be a lifesaver. This long-range radio transmitter and receiver connects locally via Bluetooth to the GoTenna app on mobile devices (iOS and Android). You can send private one-to-one or group messages and even share GPS coordinates with other users in the area. For most outdoor terrains, the range is between one and four miles. If you're using them in urban areas, it's around one mile or less, but that's still useful for finding nearby friends at crowded events where cell service is overloaded. The company has provided us with two pairs of GoTennas for a couple of lucky readers this week. All you need to do is head to the Rafflecopter widget below for up to three chances at winning.

Winners: Congratulations to Manuel O. of Brooklyn, NY and Adrian T. of Toronto, ONT!
