3khz coil

[7centsworth]

I have a 3khz coil on order and can' t wait to try it out. But I have a question how many of yall use it and what are the pros and cons? Also what do yall hunt mainly with it? Thanks.

I hunt for old coins at old sites. And since the 3 kHz was introduced 4 years ago, I always use it in wide open spots. Not only because it is theoretically better with higher conductive silver and copper. But being better suited for higher conductive targets results in it not as well suited for lower conductive targets (like deep iron). I hunt a lot of old farmsteads. And I usually hunt with a minimal amount of discrimination and multiple tones. Many of these sites are littered with rusty nails from fences and barns. I find these ferrous targets produce a very distinct audio response that is more easily distinguished by my using the 3 kHz coil. When I get an "iffy" target, I simply sweep back and forth over it, while dragging the coil back toward my feet. As the target leaves the detection field, if it produces multiple low audio tones, you can bet it is not a coin. These pitch differentiations are best heard with the 3 kHz coil, because the properties of ferrous targets are more easily identified at lower frequencies. As the detector's frequency increases, it becomes more difficult to identify those ferrous properties. By combining the 3 kHz coil with target sizing and other techniques I've learned, I'm able to effectively eliminate most of the deep iron from my hunts.

You can search through the past posts and pull up dozens of "opinion's" on the 3 kHz coil. Here are but a few of mine.....
