Sorry I've no current numbers for a digger.
Buy your own pump might be one answer, but can't say I have grasped the knack myself, I'd at least want a pack from a shop to start me off whilst I had a go at getting some of my own on a suitable tide.
For Rhyl I'd rather have fresh lug on the hook too.
Frozen if not fresh peeler crab could be well worth tracking down though.
Did you catch?
