Buying Guide for the Best Cheap Metal Detectors
Choosing a metal detector, even among more affordable options, should begin with a clear sense of where and how you plan to use it. Start by thinking about whether you'll mostly be in parks, at the beach, or on hikes. Also, consider whether you want to look for coins, jewelry, or perhaps tiny relics. A good beginner-friendly detector balances ease of use with decent detection ability, so picking one with the right features can really help you enjoy the hobby without feeling overwhelmed. Take time to learn about key features rather than just picking the least expensive option - this approach will help you get a detector that truly matches your needs.Detection DepthDetection depth tells you how deep below the surface the metal detector can sense objects. This is important because deeper detection can help you find items that others have missed, but deeper isn't always necessary for every situation. Entry-level detectors usually offer reliable detection up to 6-8 inches for coin-sized objects, which is enough for beginners or those searching in parks and cleansed areas. If you're searching on undisturbed land or want to dig a little deeper (10-12 inches), look at models that promise higher detection depth. Pick a depth that matches where you plan to hunt: for casual coin hunting, you don’t need extreme depth; for searching older, wilder areas, higher depth can pay off.
Discrimination/Notch ControlsDiscrimination is a feature that helps you filter out unwanted metals, like iron nails or aluminum tabs, so you spend less time digging trash. Cheaper detectors may have simple discrimination, such as a dial or basic preset levels, while pricier ones allow more precise control over what you want to ignore. If you simply want to find coins or jewelry in relatively clean areas, basic discrimination will suffice. On sites with lots of junk, more advanced discrimination can save time and frustration by only detecting the objects you want.
Target IdentificationTarget identification lets you know—or guess—what kind of metal you've found before digging. This usually shows as a number or a visual icon. Entry-level detectors often have a simple display or a few indicator lights, while more advanced models show a digital readout with more detail. For beginners and casual use, basic identification is enough and helps you decide whether to dig or skip a signal. If you prefer knowing exactly what you’re detecting, look for models with clearer numeric displays or target icons.
Operating FrequencyOperating frequency is the speed at which the detector sends signals into the ground. Lower frequencies (under 10 kHz) penetrate deeper and are good for finding larger objects or coins. Higher frequencies (over 10 kHz) are better for small, thin items like jewelry but work at shallower depths. Most affordable or general-purpose detectors operate at a single moderate frequency, which suits most beginners. If you're targeting a specific type of item (like gold nuggets or tiny relics), look for a frequency range that matches your goal.
Water ResistanceWater resistance indicates whether your metal detector can handle wet conditions, such as morning dew, rain, or shallow water. Some detectors have waterproof coils, so you can use them at the beach or in streams, while others are best kept dry. For general park or dry land use, basic water resistance is enough. If you want to search beaches, riverbanks, or anywhere wet, look for a detector with at least a waterproof coil or better yet, a fully water-resistant design.
Weight and ErgonomicsThe weight and comfort of a metal detector matter because you'll hold and move it for long periods. Lighter detectors are easier for beginners, children, or those with physical limitations, while heavier, more robust models might be more durable but tiring. Look for an adjustable shaft and padded grip so you can adjust it to your height. If you plan to hunt for more than an hour at a time, go for a model you can comfortably swing for as long as you need.
