If you dont want to share dont respond!
And where is your sharing contribution in all this?
George Payne did research years ago which indicated that silver U.S. dimes respond best to a frequency of 2.7kHz, and that most U.S. coins show up best when utilizing a frequency of 10kHz or below. Also that gold responds best to frequencies of 20kHz or higher.
Additionally, lower frequency will penetrate the ground deeper than higher frequency. It's not a HUGE difference, but it can matter where a couple of inches may mean the difference between success and failure.
True all things being equal. But all things aren't equal. Circuitry design plays into it way more than actual freq and no two manufacturers and/or models use the same circuitry. There is no way an Ace 150 at 6.5kHz is going to see a silver coin deeper than and AT Pro running at 15kHz. Why, because the circuitry on the ATP is more refined/advanced.
