Heres a picture from the last deer I shot..You can see at the borrom of the pic, a flo green nockinside an orange FOBlaying on the ground at the point of impact..In the back ground (in the blood) you'll see a red light light..thats my arrow..I make a lighted nock to work with FOBs

The fob is made to pop off...so you loose your nok! but it stays there so you know where your shot was located..
I have a couple dozen FOBS here...haven't tried them...Paul sent them out here for me to use on film.
