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?
3. What do I need to know about my detector’s batteries?
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.
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.
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?
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.
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.有关负责金属检测的更多信息。
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!
