Coil Applications

9-Inch 7.5 kHz Concentric Coil

The stock 9-inch 7.5 kHz Concentric coil is an excellent “all-around” coil.

It is good for coin shooting, relic hunting and general detecting. It oers

excellent depth in moderately mineralized soils. And, it provides excellent

target response on targets of all conductive levels. So, if you’ve only got

the 9-inch Concentric at 7.5 kHz, don’t feel you have to run out and buy

more coils. However, I believe the 9-inch Concentric coil at 3 kHz provides

more audio information for the types of targets I hunt, and the places I

hunt them.

I may not be a typical coin shooter in that I like to hunt in All Metal, with

multiple tones. Actually, I usually hunt in a Discrimination Pattern without

any notch segments rejected, as in zero-discrimination. I didn’t always

hunt like this. But I have proven to myself that I was missing targets

by not hearing everything that passed under the coil. For example, if

I am running a Discrimination Pattern that rejects ferrous targets, the

detector will blank out every time the coil passes over one of them. Then

if there happens to be a coin laying between two nails, I am more likely

to miss it (target masking) when the Threshold blanks out on both nails,

as opposed to the Threshold being replaced by the low tone of a nail,

followed by the high tone of the coin, followed by another low tone nail.
