Good factsheet!!
I am Scout Leader of the 8th Burgess Hill Scout Troop, along with Tootsies Trackers. We promote geocaching with the scouts and a number of them have done some of our local caches and we did have a TB that got washed away in Florida Floods!
Anyway, I did notice a typo on page 4 of the scouting factsheet where it gives a list of functions that a GPSr might want to have, it states WASS instead of WAAS
Cheers
Mark
