the key with the Coin$trike I found was to listen especially for repeatable high tones and ignore the numbers and just keep digging until you finally reached that high tone half way to China. I watched my hunting buddy using my Coin$trike dig a deep Roosie at least 8+ inches that I couldn't hear with my CZ-70 at a sensitivity of 6. He also dug a key date 1870 IH when he first set the detector coil down at my honeyhole 1830's farmsite that I hunted to death with my CZ-70. Thanks...HH
