Hi guys haveing been told that raw diamonds flouress when black lite is shone on them i had a thought that if i towed a black lite behind a quad bike and then had a means of looking at the lite through a optical device then a sprectrum interface of some description then to a laptop on my handle bars of the quad i could cover alot of ground looking for diamonds and if i found one i could see the sign on a bargraph or similar scale on the laptop,Now i would presume there are going to be alot of varibles so the question is,is this a viable way to go about this and where would i look for the bits and pieces to do the project .Thank you,Peter Evans.
