The response to dirt samples is interesting. Ran the Axiom against 6000 (and occasional GPZ) over this last few months. We did do some testing, that showed the Axiom able to keep up on the small stuff with both set to highest gain but more difficult to keep there, to hear similar signals through the local ground conditions. I don't find the advice to simply turn down the gain/reduce noise on the Axiom would apply to finding the most gold, more just making a more pleasant experience. In some places it was very noisy at mid-high gain, in others it was useable where the 6000 had a long tail that made it less than ideal. Axiom found every hot rock, 6000 no slouch there but Axiom very quick to dismiss them. Overall, and given the additional metal check- I came home thinking of what Steve had said regarding owning both. I agree ; Good luck deciding. I'm selling my Axiom as I was given a 6000 as a gift and my disposable income will trump personal desires.
