It depends what you mean by 'do as I'm doing',all you really need is a detector,spade and a understanding landowner.
It helps,if you are going "cold calling" for permission to detect,if you have appropriate insurance too:-
Membership
I have permission from local councils to detect on certain open spaces (parks etc) as well as permission (from "cold calling") off some local farmers.
Though I've never been,I also have a permit from the crown estates to detect on certain parts of the foreshore (not Bpool that would be down to local council).
it's free if you want to apply:-

Also,I keep all my spendable coppers in a jar,if it was £1,£2 coins I'd be guilty
