The Pieps Vector is the first avalanche transceiver to incorporate GPS technology. It’s a welcome addition. For starters, you can use the Vector as you would any other GPS device. But it’s also helpful in the event of a slide. While GPS signals won’t lead you directly to your buried buddy—the location information they provide is too general—they do allow you, thanks to the principles of tri-angulation, to figure out the relative position of the signal much faster, saving you, and him, precious time.
