With the help of a communications device from a Maine company, you can now Tweet from nearly anywhere on the globe, even on top of Mount Everest.

That’s where American climber Eric Larsen was Friday, when he tweeted “Everest summit,” with help from his Earthmate PN-60w, a handheld GPS device from Yarmouth-based mapping and satellite communications firm DeLorme.

Just a few days earlier, DeLorme and a partner company won a Popular Mechanics’ Breakthrough Award, which recognizes products and innovators that “move society forward.”

When used with a satellite communication device from California company SPOT, PN-60w users can type and send personalized text messages from virtually anywhere in the world via satellites. The devices do not rely on cellular phone signals.

DeLorme’s PN-60w with SPOT satellite communicator costs $549.95
