1. At what depths can a detector find treasure?
It’s impossible to predict with complete certainty how deep a specific detector can be expected to find metal. This is because there are a variety of factors that affect a detector’s performance. For example, the amount of minerals in the soil, the type of metal that’s being detected and the quality of the detector itself impact how deep your detector will hunt. The size and surface area of a target also affects detection. For example, the larger a metal target, the easier and more deeply it can be detected. Using a searchcoil larger in diameter can also help a detector achieve greater depth. A 12.5" searchcoil produces a more extensive magnetic field that penetrates the ground more deeply to find objects at depths that a smaller size searchcoil can’t reach.
Slowly and methodically sweep your searchcoil from side to side, keeping it one to two inches above the surface. Overlap each sweep by advancing the searchcoil by about one quarter to one half of its diameter. Scanning in a straight line helps to keep the searchcoil level and the overlap sweeps uniformly while reducing the likelihood of lifting the searchcoil after each sweep. Listen for a peak in the audio sound. Hold the searchcoil one to two inches off the ground and slowly sweep it back and forth in an X pattern. Note where the sound becomes the loudest. The target should be located in the center of the imaginary X. Many of today’s modern metal detectors are equipped with an electronic pinpoint button. Read your owner’s manual for complete electronic pinpointing instructions.
NiCads (nickel/cadmium) and nickel metal hydrides are rechargeable batteries that last between 8 and 12 hours and cost up to 10 dollars each. Alkalines are disposable batteries that last between 25 and 30 hours and cost about two dollars each. Because extreme temperatures can drain battery power, it is recommended that you always carry a spare set of batteries. In cold weather, attaching the battery pack to your belt under your jacket can help keep batteries warm and dry.
5. What is True Size?
Yes. To achieve the greatest depths when searching for large, cache sized-objects, many professionals hunt in the All-Metal mode and use a large searchcoil.
7. What is the significance of a detector’s Operating Frequency?
For maximum success and privacy when treasure hunting you should use headphones. They are essential in noisy areas and enhance audio perception by bringing the sound directly into your ears.
10. Are there any laws surrounding treasure hunting?
Every square inch of property in the United States is owned -- by an individual, group, corporation, governmental body, etc. And, there are definitely laws that have been written to apply to various treasure hunting situations. Each state has its own statutes concerning where you can and cannot search and whether you may keep the treasure you find. You must learn these laws, and remember that they can be changed at any time.For more info on Responsible Metal Detecting.
