[QUOTE="neddy, post: 355728, member: 6979"] Put down a small test nugget. If you haven't got one use a tiny piece of lead. Bury it in ground a couple of inches, and see if you can hear it. Play with the threshold and set it at a position you can hear the target the clearest. If you set your threshold too low you wont hear it. Same if threshold set too loud. Also try different sensitivity settings, too high it will get noisy particularly if ground is highly mineralised and you will not hear target. Most target signals are not loud particularly deeper targets. I used to own an exterra and found the little 6 inch round coil was good for small gold, better than the eliptical. When you use a test piece put it in a small piece of brightly coloured piece of tape. So it is easily seen. I use three different sized test nuggets. This will help set up your machine to suit different conditions mineralisation etc. [/QUOTE]
