I use a #0 or #1 long spring, clear vegetation away from the hole and place the trap upside down with the pan over the hole. Ideally the gopher will try to push past the pan and you get a perfect neck hold.
It also works when the gopher is outside the hole and tries to get back down the hole. The key is having cleared away any stone or vegetation that would hinder the trap closing completely.
