On my first trial with the GP 3000, I went to a nearby area that has received a fair bit of attention over the years and which I had previously gridded with the GP extreme. The GP 3000 threshold was noticeably smoother and more stable despite the somewhat variable ground. After a couple of hours I heard a sound, so using the 'ground balance and switch to fixed' technique, I re-checked the sound and was still uncertain. Eventually I decided to dig and on trenching out about 8 to 9 inches, I put the coil in sideways and the audio screamed. At 15 inches I unearthed a solid nugget that weighed in at exactly 62gm or 2 oz…a bloody good start to the GP 3000! Congratulations Minelab on yet another excellent prospecting machine.
