DeLorme AG-008449-201 - $100 + shipping
This palm-size device will send text messages, post to Facebook and Twitter, signal rescuers, and track real-time progress on an online map, but paired with an Iphone or Android phone, the inReach also lets you send and receive text messages.
I’ve used it and like its features, particularly being able to text my GPS location to friends who were joining me after I claimed our camping spot. I’m selling it because I’ve not used it enough to justify the subscription service ($120/yr). Device is in like new condition.
