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.
2. How do I pinpoint a target?
缓慢而有条不紊地扫你searchcoilside 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.
3. What do I need to know about my detector’s batteries?
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.
4. What is discrimination?
Discrimination refers to a metal detector’s ability to reject a target, such as a pull tab and foil or accept a target such as a coin or piece of jewelry based on its metallic composition. With features like Target Imaging and Tone ID, your detector can tell you what your target is before you ever dig.
5. What is True Size?
真实大小的获得方式与真实深度几乎相同。在GTI金属检测器中，多个接收器添加了目标ID的其他维度，而不仅仅是材料ID。但是，最终，多个接收者之间的相互关系才能提供这些真实的测量值，而不仅仅是拥有它们。真实的大小和深度是Garrett独家功能，只有Garrett GTI探测器才有可能，该探测器旨在为寻宝者提供有关目标前的最准确信息。
6. Is overall depth compromised when searching with discrimination?
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?
一个metal detector transmits magnetic energy into the ground and senses distortion in the magnetic field due to the presence of a metal object. The frequency content, temporal form and amplitude of this magnetic energy can affect detection capabilities and overall performance characteristics. There are two primary detection technologies used in today’s metal detectors: Single Frequency (also known as Continuous Wave) and Multiple Frequency (e.g. Pulse Induction and Dual Frequency). Each technology has its own detection characteristics, understanding these will enable you to choose the right detector for your treasure hunting needs.
8. Do I really need headphones when treasure hunting?
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.
9.我需要的不仅仅是一个搜索螺柱吗？
搜索螺旋是金属探测器的重要组成部分。它是平坦的，通常是圆盘，它会在周围环境中产生磁场并感知金属目标。它位于茎的末端，并通过茎周围缠绕的电缆连接到对照壳。磁场的大小，深度和能量输出（功率）取决于搜索线的形状和大小。了解各种尺寸和形状背后的搜索夹夹的目的将使您能够为正确的应用程序选择最佳的搜索coil。有关可选搜索螺旋的类型和好处的详细说明，请阅读我们的搜索磁盘技术表。
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.
