Minelab Equinox Two Tone Gold Hunting Skills

These are just a few observations from the salt and fresh water sites I hunt.  Overall, the Equinox is better in black sand than even the CTX—it just does a better job of processing and gives you the fidelity to adjust the recovery speed to ride over black sand. I find 5 to be a good setting in tough sand. The Equinox is also better on deep low conductors—especially with the “Horseshoe” button pressed. This is an important setting to get maximum performance in two tone. Also,, where you have a response that’s broken or going from above zero to below–going back to straight disc is a good way to see which side of the line it falls on. 

Two Tone:

Lets you hear the “ramp up / down of signals—enhancing the Equinox’s strength as a consistency checker.

Lets you hear how the detector is processing the ground and make effective signal balancing adjustments (Gain, Recovery Speed…). Where you hear the ground sounding off as you sweep, either slow down your sweep, or bring the Recovery Speed up.

Note: It’s a lot harder to signal balance the 15” coil.

Lets you co-ordinate the signal tone and meter reading with your coil movements to see how distinct from the ground something is.

I like to run the non-ferrous (T2) up at 24 or 25 to hear more detail.

Hit your targets with a slightly angled second pass—this will tell you how consistent something is—whether it’s a solid object or just the machine responding to a ground change or iron. Where you hear extension in the tone—these are the non-ferrous responses. It’s possible to become very accurate this way—you can tell if something is corroded or a weak target responding in concert with the ground—such as thin foils do. 

As you hunt, continually try to learn how the machine responds to different strengths of signals at various distances from the coil. I even swing over metal objects I see on the surface—just to hear the strength. This will help you to develop the skill of looking for “sets” of target characteristics—size, strength, consistency, depth. As I’m walking between sites I even test the field strength on my scoop. It’s like you are calibrating a meter in your mind—too small versus too big versus just right…

You don’t need high Gain settings to get great depth this way. I run at “19” most of the time. This lets the signal reach down into the ground well—and gives you clean, full tones to interpret. With higher settings there are also more “sound offs” that need to be examined. A high Gain signal—say 22 plus is a “forced” sounding signal.

I run the F2 Bias pretty high to knock out caps and slag. (That’s my beach conditions). This is a beach gold hunting method—it will also reduce to response to alloys such as brass or steel clad coins. This way when I hear a clean tone I know it’s aluminum—or gold.

Still amazes me the depth this way of using the Equinox will get on deep foils and gold!

Good Luck Detecting,
