No, I haven't used a metal detector - I'm not out digging any more. I work on the computer reconstruction side of things now and all the sites I work on are rock art/wall painting ones. I can only go on the reaction to metal detectors in N.Ireland and the Rep. of Ireland as those are the places where I dug. The Republic of Ireland is particularly strict with laws concerning archaeology (which is definitely a great intention, even if it does get petty and bureaucratic at times). Next time I'm home I'll ask what the current views are, and I'll chat to my mates to see what the reaction would be on their sites. I'm not hardline aginst metal detectors, just extremely concerned about unecessarily disturbing sites and unwittingly destroying information. That covers concerns about poor archaeological practice as well!
