I bought that ELT from Kitfox. It is capable of connecting to an inexpensive GPS. I don't have it connected to a GPS though.

I do a lot of hiking and snowshoeing alone in the back country. I read a story about a hunter that broke his leg 10 miles from the nearest road in Idaho. It took him a week to crawl out.

That sold me on the PLB as a good compromise to go along with the 406 ELT in the plane. I keep it in my pocket when flying.
