I dig it
I spent this morning playing with my new beacon It has the same range as my old M1, twice the range of my old F2 and only like 10m less than my prized M2. Oh ya, its only like half the size of any of them.
It would be cool if you could mark a target and search for the second victim in a mutable burial situation. But that is a relativity new feature in beacons and its not hard to work around if you are well practiced.
Best part is that this thing is only a little bigger than an Iphone so its not problem to take it every where every day.
