Wow! What a story! And so many forum members involved. This is just what I need to jog my complacency before our trip. Many years ago while living in Alaska, a guide told me "people die here everyday". Most survive the accident but don't get found in time. Thanks to all for their tips on PLB's. for those on a budget, my group and I were encouraged by our wives to move to the rino GPS units. If someone is incapacitated you can still "ping" their radio without their input.
We are all older ex-military and initially thought we don't need no stinking GPS radio! Now it is our bare minimum safety. I would no sooner leave camp without a survival kit.
Glad the story ended well for Dave. Y'all be careful out there!
