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.如何查明目标？
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.
3.我需要了解探测器的电池吗？
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.
4.什么是歧视？
歧视是指金属探测器拒绝目标的能力，例如拉动tab和箔纸或接受基于金属成分的硬币或珠宝等目标。借助目标成像和音调ID之类的功能，您的检测器可以在挖掘之前告诉您目标是什么。
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，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，这些探测器旨在为寻宝者提供有关目标前的最准确信息。
6.整体深度搜索时妥协的智慧吗h 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?
金属探测器将磁能传输到地面，并由于存在金属物体而在磁场中感受到失真。这种磁能的频率含量，时间形式和幅度会影响检测能力和整体性能特征。当今金属探测器中使用了两种主要检测技术：单频率（也称为连续波）和多频率（例如脉冲诱导和双重频率）。每种技术都有其自身的检测特征，了解这些特征将使您能够为寻宝需求选择合适的探测器。
8.寻宝时我真的需要耳机吗？
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？
搜索炮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，并通过在茎周围缠绕的电缆连接到控制壳。磁场的大小，深度和能量输出（功率）取决于搜索套件的形状和大小。了解各种尺寸和形状背后的搜索套装的目的将使您能够为正确的应用程序选择最佳的搜索套件。有关可选搜索夹的类型和好处的详细说明，请阅读我们的SearchCoil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.

11. Are there online forums or treasure clubs I can join?
寻宝者有无数的在线论坛分享自己的技巧，帮助其他业余爱好者使用探测器，当然还炫耀他们的最新宝藏。您也可以联系当地的经销商，他或她可以指向其他寻宝者在您自己的后院举办的所有激动人心的俱乐部和活动！
