Using a metal detector is a science in itself—particularly, discerning its individual beeps and tones. Once you have mastered your detector, you can focus on how deep you are finding targets. Some hobbyists only focus on targets that are buried 2-5″ deep. Others swear that their best targets are buried much deeper. Civil War relic hunters often talk about great finds buried 10″ and more underground. If you are looking to find better treasures, you may consider a detector that is built to find deeper targets, such as the Teknetics T2, Fisher F75. or Detech Chaser. One well-known treasure hunter who makes videos, “Aquachigger,” always digs deep holes while searching 1800’s homes- finding “Seated Liberty” quarters, Indianhead pennies, muskets, belt buckles and buttons.
Listening to Your Signals
The textbook coin signal is “round”. What this means is that for coins laying flat, the signal has the same characteristics no matter what angle you scan it. As you walk around the target while swinging the coil back and forth, a coin sound will be smooth and repeatable. If it beeps for half an inch one way, the “round” signal will beep for half an inch every other way. Oversized objects (like pop or beer cans), may give loud signals from one angle, but no signal from another.
Get the Most Depth Out of Your Detector
Here are expert tips to get the best depth out of your metal detector:
- Turn up the Sensitivity. You can find the optimal setting for the particular conditions you’re using, but you’ll have to fine-tune it.
- Adjust the Ground Balance to be neutral or slightly negative. If your ground balance is positive, it’s easy to overlook a lot of stuff.
