[leadin]’Turn your smartphone into a walkie-talkie.’ That’s a simple premise of the Beartooth device, a new kind of tech-outdoors product that goes on sale today.[/leadin]
I saw a prototype of this “off-grid communications device” last month in Utah. It’s a sleek, half-inch-thick unit made to be stashed in a jacket pocket or backpack lid.
The Beartooth functions as a two-way radio in tandem with your smartphone. Pair it via Bluetooth with an iOS or Android phone and it gives a 2-mile range using radio signals.
It does not require Internet or cell networks, meaning you can communicate anywhere.
Two Beartooth devices are required to talk or text phone-to-phone. Each phone needs its own unit. They sell as a set of two for $249 (early bird price) but will not ship until late 2016.
