You will need far more than 2 ferrets to start out ie carry box, nets, locator + collars, spade and a hedging hook (was I the only person who always took one of these?)
Carry box you can make yourself easy nets are quite cheap, spade you prob got one! hook not essential but very handy, locator and collars very expensive!!!!
Its not a cheap game anymore but can be a good day out.
As has been said mate knock on a few doors. Have just got rid of my ferrets because I do far more shooting at night now.
