I use a gundog or some type of terrier to tell me if there is in fact a rabbit in the hole ,then you can either pop a catch net over the hole or just use the shotgun as the rabbit bolts out at top speed.The ferret after it has been entered into the hole gos down deep using its nose to "find" the rabbit and will attack either killing it or moving to on to bolt out .We sometimes run them down with a running dog ,usually a greyhound or whippet after they bolt .
