Dowsing works but don't just take my word for it!

I was delighted to receive this email the other day:
Hi David,
It's taken me a while but I thought I'd write to you to let you know of my experience after reading your book [The Successful Treasure Hunter's Essential Dowsing Manual] which I purchased last year.
After quickly reading through it I thought how interesting it seemed, but reserved judgement until I could put something into practice.
It wasn't until two weeks later that I remembered that I hadn't "had a go" at the general idea, so the night before our club search I got the map out and looked for a pendulum.
I couldn't find anything suitable so picked up the first thing from my desk tray which happened to be two safety pins. I hooked one into the other and let the other pin "dangle" to give some kind of feedback.
I was amazed to find that I received a reaction from a certain part of the area on the map.
The next day I found that we were detecting on the other side of this area and come lunchtime nothing of interest had been found. I jokingly said that I wasn't surprised as the treasure was over on the other side. The site secretary said that the only available part of this area was a small part which was stubble and the rest had been set, but I was welcome to have a go on the stubble.
Feeling I had nothing to lose I started detecting on this area and after a couple of hours had found nothing. Then I unearthed what looked like a large ornate ear-ring with a heavy hook.
This turned out to be a very handsome Tudor silver gilt cap hook, declared as treasure which has since been disclaimed and returned to me.
My find was then followed by others finding a literal "hoard" of tudor buckles in one area, probably a dozen in all.
Needless to say we returned the following week and after showing the farmer my previous find I went straight onto the field and my first signal was a 9ct gold gents signet ring.
Others unearthed a Mary Groat, a large Roman fantail brooch and then the best of all one of our club members found a Roman Gold Aureus.
I cannot say for sure but either the safety pin or myself certainly picked up on something that night!
Regards
John R.

THANKS JOHN!
