Buying Guide for the Best Garrett Metal Detectors
Choosing the right metal detector can be a fun and rewarding experience, but it requires some understanding of the key features and specifications that will best suit your needs. Whether you are a beginner or an experienced treasure hunter, knowing what to look for in a metal detector will help you make an informed decision. Here are some important specifications to consider when selecting a metal detector and how to navigate them to find the best fit for you.Operating FrequencyThe operating frequency of a metal detector refers to the number of times the signal is transmitted and received per second. This is important because different frequencies are better suited for detecting different types of metals. Lower frequencies (1-4 kHz) are better for detecting larger, deeper objects like relics and coins, while higher frequencies (above 15 kHz) are more sensitive to smaller objects like gold nuggets. If you are looking for a versatile detector, a mid-range frequency (5-15 kHz) is a good choice.
DiscriminationDiscrimination is the metal detector's ability to distinguish between different types of metals. This feature is important because it helps you avoid digging up unwanted items like nails or bottle caps. Metal detectors with good discrimination settings allow you to filter out junk and focus on valuable targets. If you are searching in areas with a lot of trash, a detector with advanced discrimination capabilities will save you time and effort.
Ground BalanceGround balance is a feature that helps the metal detector ignore mineralization in the soil, which can cause false signals. This is important for detecting in areas with highly mineralized soil, such as beaches or gold-bearing regions. There are three types of ground balance: preset, manual, and automatic. Preset ground balance is suitable for beginners and areas with low mineralization. Manual ground balance allows for fine-tuning and is better for experienced users. Automatic ground balance adjusts on the fly and is ideal for varying soil conditions.
Search Coil Size and TypeThe search coil is the part of the metal detector that senses the metal objects. The size and type of the coil can affect the detector's performance. Larger coils (over 10 inches) cover more ground and detect deeper objects, but they can be less sensitive to small items. Smaller coils (under 8 inches) are more sensitive to small objects and are better for detecting in trashy areas. There are also different types of coils, such as concentric and double-D. Concentric coils are good for general use, while double-D coils offer better depth and mineralization handling.
Target IdentificationTarget identification (ID) is a feature that helps you determine what type of metal you have found before you start digging. This is important because it can save you time and effort by allowing you to decide whether to dig or not. Target ID is usually displayed on a screen and can show a range of values or icons representing different types of metals. If you want to maximize your efficiency, look for a metal detector with a clear and accurate target ID system.
Depth IndicatorThe depth indicator shows how deep the detected object is buried. This is important because it helps you gauge how much effort will be required to retrieve the object. Depth indicators can be especially useful for beginners who are still learning how to interpret signals. If you want to avoid unnecessary digging, choose a metal detector with a reliable depth indicator.
Weight and ErgonomicsThe weight and ergonomics of a metal detector are important for comfort and ease of use, especially during long detecting sessions. A lighter detector is easier to handle and reduces fatigue, while good ergonomics ensure that the detector is comfortable to hold and use. If you plan to spend a lot of time detecting, look for a model that is lightweight and has an adjustable shaft and comfortable grip.
