Your probably right, but threads like this that I have read in the past, once one answers, in this case yourself, then others tend to come on board also. I see that you are very keen on searching, I can only presume that you use a detector. Let's hope you turn up a gt 3 fuze then. Are you any good at taking a picture and posting onto a page like this, if you are, then is it too much to ask for a picture of your fuze remains that you took the needle measurements from. Thanks again for your help, TED.
