1.探测器可以在什么深度找到宝藏？
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?
慢慢有条不紊地扫过搜索螺旋，从而使其在表面上方一到两英寸处保持。通过将搜索螺旋前进大约四分之一到一半的直径，重叠每个扫描。在直线上进行扫描有助于保持搜索串联级别和重叠均匀的扫描，同时减少每次扫描后举起搜索套件的可能性。听音频声音中的峰值。将SearchCoil握在地面上一到两英寸，然后以X模式将其慢慢扫荡。注意声音最大的位置。目标应位于虚构X的中心。当今的许多现代金属探测器都配备了电子精确按钮。阅读您的所有者手册以进行完整的电子精确指示说明。
3. What do I need to know about my detector’s batteries?
NICADS（镍/镉）和镍金属氢化物是可充电的电池，持续8至12小时，每个电池的成本高达10美元。碱是一次性电池，持续25至30小时，每个电池的成本约为2美元。由于极端温度会耗尽电池电量，因此建议您始终携带备用电池。在寒冷的天气中，将电池组固定在夹克下的皮带上可以帮助保持电池温暖干燥。
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.
5.什么是真实大小？
True size is obtained in much the same way as true depth. Multiple receivers, within a GTI metal detector, add additional dimensions of target ID, not just material ID. Ultimately, however, it’s how multiple receivers relate to one another that provides these true measurements, not just merely having them. True size and depth are Garrett exclusive features and are only possible with Garrett GTI detectors, which were designed to give treasure hunters the most accurate information about a target before they dig.
6.搜索歧视时，总体深度是否会受到损害？
是的。为了在搜索大型缓存尺寸的目标时达到最大的深度，许多专业人士以全金属模式进行狩猎并使用大型搜索套件。
7. What is the significance of a detector’s Operating Frequency?
A 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?
为了获得最大的成功和隐私，您应该使用耳机。它们在嘈杂的区域至关重要，并通过将声音直接带入您的耳朵来增强音频感知。
9. Do I need more than the one searchcoil?
The searchcoil is a vital part of your metal detector. It is the flat, typically circular disk, which generates a magnetic field and senses metallic targets in the surrounding environment. It is located at the end of the stem and is connected to the control housing via a cable that is wound around the stem. The size, depth and energy output (power) of the magnetic field is determined by the shape and size of the searchcoil. Understanding the purposes behind the various sizes and shapes of searchcoils will empower you with the ability to choose the best searchcoil for the right application. For a detailed explanation of the types and benefits of optional searchcoils read our Searchcoil Tech Sheet.
10.围绕寻宝活动有任何法律吗？
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?
There are countless online forums where treasure hunters share their own tips, help other hobbyists with their detector, and of course, show off their latest treasure. You can also contact your local dealer, he or she can point you towards all the exciting clubs and events that other treasure hunters are hosting right in your own backyard!
