Ive got an old tip that been very productive over the years .....the ground on our hunt has a bit of everything on it and in over 5 years I don't think ive had an easy dig...plenty of shallow ones too but not easy and when you see 2mtr and above on the box you know your in for the long hawl ...some proper horrible stuff ....dug in the Cotswolds a few times or I mean chipped ...it wasn't much fun
