Ok, so after by first foray in to ferreting yesterday and with my 10 year old hooked, it's time we thought about working his 2 Jills they're friendly enough pair (unless you're the wife who they find quite tasty as they tend to nip her!) and the gardening training is under way with them running in and out of tubes etc. I have a 15ft Mk1 Deben Ferret finder with one collar so I need another collar, question is do the Mk3 collars work on the Mk1 box?
Any advice greatly received
