Buying Guide for the Best Low Cost Metal Detector
When choosing a low-cost metal detector, it's important to focus on features that match your intended use, whether that's casual treasure hunting, beachcombing, or searching for lost items in your yard. Understanding the basics of how metal detectors work and which specifications matter most will help you find a model that provides good performance without unnecessary extras you may not need.Detection DepthDetection depth refers to how deep the metal detector can identify and signal the presence of metallic objects under the ground. This is important because if you want to find items buried deeper, you need a detector with better depth performance. Basic models may detect small items (like coins or jewelry) up to 6 inches, while larger objects may be detected deeper. If you mostly look for shallow coins or jewelry, typical entry-level depth is enough; but for deeper relics, a device with greater depth might be necessary.
DiscriminationDiscrimination is the detector's ability to distinguish between different types of metals, such as iron, aluminum, silver, or gold. This is important because it helps you avoid digging up unwanted objects like nails or bottle caps. Low-cost detectors can offer simple discrimination features, usually letting you filter out some unwanted metal types. If you are focused on finding valuables, even basic discrimination helps you spend less time on trash.
Sensitivity AdjustmentSensitivity adjustment lets you control how responsive the metal detector is to small or deep objects. High sensitivity can find smaller items, but also increases the chance of false signals from tiny metallic debris. Lower sensitivity reduces false alarms but might miss weaker signals. If you plan to use the detector in areas with a lot of trash or mineralized soil, the ability to tune sensitivity will help you get better results.
Coil Size and ShapeThe coil is the round or oval part at the bottom of the detector that sends and receives signals. Coil size affects the area you can cover and the depth you can reach. Smaller coils are good for pinpointing targets and working in trashy or tight spaces, while larger coils cover more ground and generally provide better depth. For most beginners, a medium-sized coil is a flexible option that balances both needs.
Ease of UseEase of use includes how simple the controls and displays are, and how comfortable the device is to carry and swing. If you are new to metal detecting, simple buttons, clear labels, and lightweight designs will make the learning process more enjoyable and reduce fatigue during longer outings. Consider this if you or family members are beginners or younger users.
Audio TonesAudio tones are the sounds the detector makes to alert you to different types of metals or signal strengths. More advanced models use multiple tones to indicate various metals or levels of conductivity, while basic ones may only have one or two tone options. Multiple tones can help you decide when to dig, but for a first device, having at least a reliable basic sound is necessary.
