Take a really close look at the inside of the collar. You are looking for old sharpie marks, or especially marks that look like they were scratched with an awl, etc. Often agencies will scratch frequency numbers along with other info on the inside, but they can be really hard to see after the collar has been on for a while. Get it under a good light and look CLOSE.
no they did not help with the hunting only after they come along for the ride back to the truck. i try not to let them run wild in this area as there are some rattlesnakes out this time of year. and thanks on the rifle its a ultra light chambered in 25x47 and works very well on everything i hunt with it up to caribou.
i've got a season ticket on a one way ride
