Guy I stalk with has one, got it for nothing, hence its name is freeby.....
Cracking little thing, I dont think it has ever missed a follow up, even after he has been called out several hours after the shot. Very brave dog, works its socks off and is generally very well behaved. My Pal swears by it. I'm a Lab man myself, but I do likr to see Freeby working.
PM me and I'll give you my Pals contact number, speak to him, he'll give you al the info you require
