[QUOTE="loamer, post: 137864, member: 981"] These are some manufacturers and dealers links with info available. The caveat is that these are manufacturers/dealers sites however I have found the info a very useful teaching aid. There are lots of others. Coil size greatly depends on the detector, your level of experience, hearing (yes hearing) levels, use of boosters/amp, soil type and depth, size and spread of gold historically recorded or suspected, headphones/speakers etc etc. If possible, borrow or hire a number of coils and test them. Myself and a couple of friends have developed a test pit site for this very reason - test, test, test. Series of holes dug horizontally into a bank to simulate various levels. Using aluminium blocks of various sizes and shapes pushed into holes gives a good testing of a detector and coils abilities. Many detectors settings have been developed by prospectors at these sites around the GT and its a hell of a lot better than air testing.
