Discrimination and Sensitivity
The coin master has two optional adjustments which is the discrimination and the sensitivity. The sensitivity makes the detector go deeper. If you’re out away from a lot of electrical activity, turning it up may increase your penetration.
If you’re close to power lines electric fences, a lot of electronic activity you might have to turn the sensitivity down to stabilize the detector.
If it’s beeping and making indications for no apparent reason, when you’re not sweep in the ground, you probably have to turn the sensitivity down a little bit to get it to work well.
So up and down with the sensitivity and that’s indicated on the display.
The discrimination is the trash rejection and you’ll see that on the screen as a speaker with the line drawn through it. As you go up with the trash rejection, you will rejecting more and more targets.
However, as you can see on the display, jewelry is all throughout icon area. So you don’t wanna set that too high for the area or you’re not gonna find a lot of the jewelry.
Typically down at the a foil rejection is where you should start out at. If you’re just digging too much junk, go ahead and turn the discrimination up a bit and you will still find most of your coins.
Tone ID and Smart Notch
The CoinMaster Pro adds 2 significant features, the Tone ID and Smart Notch. Pressing the tone ID, its indicated on by the tone ID symbol on the display.
The accepted targets produced a significantly higher pitch tone. The tone alerts you immediately that, that’s a target of interest. The tone ID is something that is really an easy to do as you’re searching along without looking at the display.
The other features is smart notch. Smart notch does something different depending on where you set your discriminator.
If you set your discriminator high and press smart notch, it brings in the nickel. The nickel is lower than the pull tab and the screw cap is higher than foil. It accepts that notch there between those two levels.
If your discrimination is set low and you press smart notch it will takes out the traditional pull tab area. These are the aluminum pull tabs from the 70’s in the 60’s, it doesn’t really apply to the later aluminum.
But in the older areas that these aluminum pull tabs can be a real troublesome, you can reject those while still running a quite a low discrimination setting and finding a lot of the Rings.
So smart notch either takes out the pull-tab or at the higher settings it pulls in the nickle range.
You going to keep the search coil in motion to detect targets and sweep the coil close to the ground, scrubbing it in grass, in rocky or sandy soils just an inch or so of the the rough surface.

Once a target is detected, the coinmaster will show the possible items and depth on the display screen.
