ACR Electronics is billing the new ACR Bivy Stick as the “world’s smallest and most simple satellite communication device,” and it certainly is sleek and simple. At just 100 grams (3.5 ounces) and 4.5 by 1.8 inches, the device fits easily in the palm of your hand, and has just three small buttons, two tiny lights, and a USB port.
The Bivy Stick pairs with a cell phone but can then be used when there is no cell phone service. One of the buttons — the check-in button — will send a prewritten, queued up message to set recipients, along with your GPS coordinates. A signal light will blink indicating the message has been sent.
There is also an SOS button on the device, which is activated by lifting a flap and holding a button down for five seconds. This will send an emergency message along with your location, updated at various intervals, from anywhere in the world to Global Rescue, an industry leader, providing 24/7/365 medical, security, and evacuation.
