Buying Guide for the Best Garrett Metal Detectors
Choosing the right metal detector can be a fun and rewarding experience, especially if you know what to look for. Metal detectors come with various features and specifications that can greatly affect their performance and suitability for different types of treasure hunting. Understanding these key specs will help you make an informed decision and find the best metal detector for your needs.FrequencyFrequency refers to the number of times a metal detector's signal is transmitted and received per second. It is important because different frequencies are better suited for detecting different types of metals and depths. Low frequencies (1-4 kHz) are ideal for detecting larger, deeper objects like relics and coins, while high frequencies (15-30 kHz) are better for finding smaller, shallow objects like gold nuggets. If you're a beginner or 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. Discrimination settings can be adjusted to filter out specific types of metals, allowing you to focus on valuable targets. If you're searching in areas with a lot of trash, a detector with good 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 metals accurately, especially in areas with highly mineralized soil or saltwater beaches. There are three types of ground balance: preset, manual, and automatic. Preset ground balance is suitable for beginners, while manual and automatic ground balance offer more control and are better for experienced users hunting in challenging environments.
Search Coil SizeThe search coil is the part of the metal detector that scans the ground. Coil size affects the depth and area covered during detection. Larger coils (10-15 inches) can detect deeper objects and cover more ground, making them ideal for open areas. Smaller coils (6-9 inches) are better for detecting smaller objects and working in tight spaces or areas with a lot of trash. Choose a coil size based on the type of terrain you'll be searching and the size of the objects you're looking for.
Target IdentificationTarget identification is a feature that helps you identify the type of metal detected before you start digging. This is important because it can save you time and effort by allowing you to focus on valuable targets. Target ID can be displayed as numbers, icons, or audio tones. Higher-end detectors offer more precise target identification, which is useful for experienced users. Beginners may prefer simpler target ID systems that are easy to understand.
Depth IndicatorDepth indicator shows how deep the detected object is buried. This is important for determining whether an object is worth digging for and how much effort will be required. Depth indicators can be displayed as numbers or bars on the detector's screen. If you're searching for deeply buried treasures, a detector with an accurate depth indicator will be beneficial.
WaterproofingWaterproofing is a feature that allows the metal detector to be used in wet conditions, such as on beaches or in shallow water. This is important for expanding your search areas and protecting your detector from damage. Some detectors are fully waterproof, while others have waterproof coils but not control boxes. If you plan to search in water or wet environments, choose a detector with appropriate waterproofing.
