John, how do you do it?
According to my calculation, you located, dug and recovered an object of value (coin, jewelry, relic) every 1:43 for two hours straight. That includes more jewelry than I found in the last 2 months. Obviously you're physically fit just to do that much digging. And you must have years of experience with the 9 (count 'em!) detectors listed.
To what do you attribute this level of success? Physical fitness, practice (experience), research, location, equipment, or luck? Jeez, I could ask dozens of questions, all pointing in the wrong direction. I'm certainly not in competition with you - we're not even in the same country! What is the secret of your success?
