购买指南最佳金属探测器
Searching for hidden treasures can be a fun adventure or a profitable hobby. However, to be successful, you need a metal detector that is up to the task of locating those buried valuables. Unfortunately, not all of them are. There are certain features a metal detector must have in order for it to be considered the best.
一个具有大线圈的单元（因此，它不会错过任何扫描上的任何东西）和小线圈（以帮助精确的位置）是理想的。拥有一个不仅可以区分材料而且可以阻止垃圾金属信号的金属探测器会使您的狩猎更加愉快。音量控制，耳机插孔和灵敏度控制都是理想的选择。
如果您想要更多提示和法律建议，请继续阅读本文。如果您准备好寻求损失宝藏的追求，请尝试我们在本文中提出的建议之一。

Did you know?
A discriminator is a small device inside a metal detector that helps you discern between a 200-year-old cache of gold and a five-year-old soda can. The discriminator compares your “hunting” results to the reaction times of known metal samples. It then displays the matching metal type.

Metal detector technology
大多数消费级金属探测器都使用旧技术，称为VLF（非常低频率）检测。VLF金属探测器使用两种相关力，电力和磁性，在检测到某物时会产生声音信号。
"Valuable metals such as gold and silver have different electromagnetic properties than “junk” metals such as iron and tin. A quality metal detector's discriminator filters out common metal hits electronically, allowing only hits from possible gold or silver sources."

How it works
A metal detector's circular base contains two wire coils: a largertransmitter coiland a smaller接收器线圈。When the user activates the detector and begins a sweep, the electricity from the battery flows into the outer transmitter coil, creating a ground-penetrating electromagnetic field. Any metal object that receives this electromagnetic charge becomes “excited” at an atomic level. In a sense, the outer transmitter coil creates a magnetic “glow” around metal objects.
一旦发射器“激发”地面上的任何金属物体，较小的接收器线圈就会接管。该线圈查找带电接地磁场的任何变化。金属物体向发射器线圈的能量发出第二磁电流。磁极性的这种变化是接收器线圈实际检测到的。信号被发送到扬声器，该扬声器根据带电金属的特性和强度发出音调。
歧视者
许多高端金属探测器还包含一个微处理器控制的分析仪，称为鉴别器。鉴别器将接收器线圈发送的信号与各种金属的已知信号进行了比较。例如，典型的金信号明显与典型的铝信号明显不同。
可以将判别器设置为从钢和铝等普通“垃圾”金属中挤压信号。这使用户可以专注于可能潜伏在地下的更有价值的金属，例如黄金和白银。
The metal detectors we research offer various search parameters. We take note of this so potential buyers can get the settings they want.
当它可用时，我们会注意到每个金属探测器的线圈深度，这表明探测器可以达到多远。
One of the most important aspects of a metal detector is the size of the coil. The bigger the coil, the more ground you can cover, and thus the better chance you have of finding treasure.
由于在检测金属时哔哔声，因此我们寻找具有音量旋钮的型号，以便用户可以控制每种哔哔声的音量。
我们欣赏具有鉴别器（微处理器控制的分析仪）的高端金属探测器，该探测器将接收器线圈发送的信号与已知的各种金属信号进行了比较。这有助于用户过滤掉垃圾金属。
我们寻找具有一系列敏感性的金属探测器，以吸引一系列寻宝者。
We appreciate metal detectors that come with headphones or include a headphone jack.
一些金属探测器最适合海滩，而另一些金属探测器最适合公园和田野。我们寻找可让您根据自己的位置拨入特定地面敏感性的模型。
我们会注意带有LCD屏幕的金属探测器，因为屏幕可以为用户提供深入的信息概述。
搜索参数
我们入围名单上的模型根据其预期受众提供了各种搜索参数。毕竟，一个在海滩上寻找宿舍的孩子的需求与野外的成人寻宝者不同。
Here are some questions to ask yourself when evaluating different products:
金属探测器的硬币深度是多少？
这是该设备实际上可以检测到硬币大小的金属块的深处的衡量标准。并非所有制造商都提供此信息。赏金猎人宣传TK4can detect coins eight inches down; the时间游侠is advertised as having a nine-inch coin depth.
Is it waterproof?
一些金属探测器完全防水，有些是10英尺。
Others have waterproof coils but can’t be completely submerged. Users should never submerge the electronic parts of these devices. Some cannot be used near water at all.
线圈有多大？
可以说，金属探测器的线圈大小最重要的是您可以覆盖的地面量。必威体育娱乐app小线圈面临的挑战是，如果您扫过太快，您可能会错过任何东西。较大的线圈有助于消除这一点。但是，较小的线圈可以帮助查明对象。
Some metal detectors will have both coils so they can do both jobs.
特殊功能
When it comes to informational displays and other features, big differences exist among the metal detectors on today’s market. When considering a purchase, look for these special features. Granted, some of them may not appeal to you, but it’s nice to know what you’re buying into.
音量旋钮
Your metal detector will beep frequently. If you’re interested in controlling the volume, you’ll want a volume knob.
Did you know?
您的金属探测器需要定期维护。润滑电线，从关节上刷掉污垢，然后在长时间狩猎后用淡水清洁。

耳机/耳机插孔
Metal detecting is a somewhat noisy hobby. If you’d rather keep your business to yourself, look for a detector with a headphone jack. Some products include headphones, too. But remember, the price of a complete kit is higher than the price of a lone detector.
灵敏度旋钮
Many metal detectors offer a range of sensitivities, which you can adjust to filter out junk and focus on what you’re looking for.
液晶屏
Some basic models do not have an LCD screen, but such an interface is a great place for the user to gather information.
地面平衡
此功能使您能够从土壤中天然金属（如铁）中“调整”干扰。
Custom notching
Notching is a lot like discrimination in that it allows the user to filter out some unwanted results. However, a bad notching system could lead to missed findings.
金属检测与法律
您不需要特殊的许可即可拥有金属探测器。但是，作为一名业余爱好者，重要的是要了解适用于金属探测器使用的一般规则和法规。
Some cities allow amateur metal detectors to search public properties such as fairgrounds, city parks, and beaches. It may (or may not) be possible for you to keep what you discover. In either case, the ground must be returned to its original condition.
一些州要求爱好者注册之前earching public properties. The laws on public metal detecting vary from state to state, so be sure to consult your local government agency before searching for treasure on public property.
如果您要使用金属探测器搜索私有财产，则该物业的所有者必须首先授予许可。所有者可以为您/她的土地的使用增加条件，例如所有权或时间限制。
If the private property you search can be claimed as protected land under an antiquities law, it’s illegal to remove any items from the site.
违反这些法律和限制的处罚可能从严厉警告到数千美元的罚款。我们敦促业余金属探测器进行一些研究，并在开始对任何私人或城市拥有的财产进行搜索之前获得所有相关的间隙。

Antiquities laws trump most property rights when it comes to the removal of metals and other objects of value.

在那里你可以打猎
有了所有这些规则和局限性，您可能想知道您实际上可以合法地使用金属探测器。实际上，仍然有许多向业余爱好者开放的地点。关键是要找到人们实际生活，工作或玩耍的地方。考虑以下领域：
Schoolyards
旧的家乡
Former factories
Beach fronts
游乐园
Recreational lakes
Note:一些州允许在水和沙丘线之间的沙滩区域进行金属检测。其他人则要求搜索者在获得州立公园和水域之前获得特殊许可。
"Places like fairgrounds, parks, sport fields, picnic spots, and schoolyards can be very rewarding for metal hunters, as they are very likely to have bits and bobs left behind by the crowds. If you are looking for silver coins or relics, try your luck at “old” and “historical” areas. Beaches are a treasure trove and regularly yield jewelry, coins, and the like."

人体工程学和性能
如果您要去寻宝，则需要一台可让您长时间使用的机器。寻找这些功能，为您找到最符合人体工程学的金属探测器：
Adjustable length
The length of some metal detectors can be adjusted based on the arm size of the user.
重量
您选择的金属探测器重多少？这似乎是一件小事，但是如果您打算花一个下午的时间在探测器上挥舞探测器，您可能会想要一些不会使您感到困扰的东西。任何大约四磅的东西都可以效果最好。
Battery requirements
Most metal detectors require batteries and few are rechargeable. Be sure to check your owner's manual for the specific needs of your detector.
Did you know?
为了通过检测器产生的电磁场充电，金属对象不一定必须具有磁性。

Tips
在进行寻宝之前，请务必了解金属探测器的正确设置和功能。如果需要，请在线阅读手册和研究。
像高尔夫一样，金属探测器需要适当的秋千才能正常工作。从一侧到另一侧缓慢地将检测器挥动，使其尽可能靠近地面 - 但请确保它不会碰到地面。
类似于拥有正确的挖掘工具，当您狩猎时，您对衣服的选择很重要。穿适合天气的舒适衣服，膝盖垫时要挖膝盖以保护膝盖，鞋子可以帮助您穿过地形，手套，以便您在sc起土壤时不会弄脏它们或割伤自己。
在开始之前，请先了解有关金属检测的当地法律。这样，您就会知道哪些区域是允许的，以及允许哪种挖掘。请记住，即使是公共区域也可能不允许金属发现是否有可能损坏的美化环境。
- If you’re new to this hobby, be prepared to find more trash than treasure. But don’t lose hope, as you never know when your luck may change. That’s part of the excitement and appeal of metal detection.
FAQ
Q: How deep will a typical metal detector penetrate the ground?
A：这个问题的答案在很大程度上取决于检测器的品牌和模型，但是通常，平均检测器可以在表面以下12至16英寸的金属块中找到较大的金属块。更深层次的搜索将需要更强大的设备，例如接地雷达。
Q: Do I need a special kind of metal detector to hunt for gold?
A：尽管大多数金属探测器都可以在一般扫描中检测到黄金的存在，但许多歧视因子很难调整其他金属签名。这就是为什么专用的金猎人经常购买特殊的金属探测器，旨在专门针对较小的金碎片“聆听”。
Q: Metal detecting seems very straightforward to me. What do the pros know that I don't?
A：For one thing, experienced hobbyists and professionals use several different types of sweeping and search patterns, not just a simple back-and-forth or up-and-down motion. Through experience and mastery, they can tell the difference between valuable metal hits and “trash” hits by the subtle changes in signal tones. Mastering the art of metal detection takes time, patience, and practice.
