High KHZ for gold detection

[canes12]

Since way back when I seem to recall that higher khz machines do better on
gold jewelry. The Omega 8 is a 7.9 khz machine which is, great on coins, wouldn't
be the best choice for gold jewelry hunting. What say you guys ?
As an unrelated question: can one run Omegas with lithium batteries ?
Thanks

The frequency is not the huge deal it once was, now that detectors have started processing those frequencies differently.

However, in spite of what some may tell you, frequency does matter. You certainly won't find a gold prospecting detector running at 10 kHz.

The higher the frequency, the more sensitive they typically are to lower conductor targets, like gold and aluminum. The lower the frequency, the better they hit on high conducting targets, like silver. Thats why your 2-3 kHz detectors often make the best coin shooters out there.

A lot of detector companies, knowing their customers want to find jewelry and coins, split the different and often set their machines to between 7 and 10 kHz to give the detectors reasonable sensitivity to both targets.

most detectors now unless there multifreq are average of 14khz which 16 khz is the ideal nickel freq so theres a broader band of things, but if coins is your game 2 to 10 khz is best suited for coins or silver anyways.

The omega will do both well but for jewelry the G2 is the top dog. Tek recommends alkaline but Lithium do work.

highest frequencies,. are the real gold machines,,whites gmt,,48kz,,,fisher gold bug,,71kz,,or so,,,thats high freq. for gold guys,,,
