How to choose the right metal detector

Updated June 2026Independently researchedNo paid placement.

What type of metal detector should I buy?

You have two main technologies to choose from: VLF (very low frequency) and PI (pulse induction). VLF detectors are the most common and work well for coin shooting, relic hunting, and jewelry hunting in moderate soil. They offer discrimination and target ID, so you can ignore iron and pull tabs. PI detectors are less affected by saltwater and highly mineralized ground, making them the go‑to for wet‑sand beach hunting and gold prospecting, but they often lack discrimination, meaning you will dig more trash. Within VLF, single‑frequency machines are budget‑friendly and fine for general use, while multi‑frequency models automatically adjust to changing ground conditions and give better depth on different sized targets. If you plan to hunt only parks and dry sand, a single‑frequency VLF will serve you well. If you want one detector for fresh water, salt beaches, and parks, invest in a multi‑frequency or a pulse‑induction model with good discrimination. Coil size also matters. Larger coils (11 inches or more) cover ground faster and find deeper targets but are heavier and less sensitive to tiny items. Smaller coils (5 to 8 inches) are great for trashy areas and picking out good targets among junk, and they are lighter to swing for hours.

How much should I spend on a metal detector?

Budget is the biggest practical filter. Entry‑level detectors (roughly under two hundred dollars) can find coins and rings at modest depths, but they usually have fixed ground balance and limited discrimination. They are fine for occasional backyard use or introducing a child to the hobby. The sweet spot for a serious beginner or weekend hobbyist sits in a range commonly described as a few hundred dollars. At this price you get adjustable ground balance, better target ID, and often a waterproof search coil. Many well‑known brands like Garrett, Minelab, and Nokta have models in this tier that perform well for parks, schoolyards, and dry sand. High‑end machines, which can run well over a thousand dollars, offer multi‑frequency operation, advanced iron filtering, wireless headphones, and full waterproofing to many feet. These are for enthusiasts who hunt often, work heavy mineralization, or search old relics and deep coins. You can absolutely find treasure with a mid‑range detector; the extra money buys convenience, depth, and better audio in trashy ground.

What features matter most for a beginner?

Start with a detector that has automatic ground balancing. Ground balance cancels out the mineral signal from the soil, and a manual or auto‑balance circuit prevents false signals and lets you hear real targets. Without it, you will struggle on anything but dry sand. Discrimination and target ID are next. A notch discrimination system lets you ignore pull tabs and bottle caps, while a numeric target ID (usually 0–99) helps you guess what kind of metal is underground before you dig. Even a basic scale is much better than a beep‑only machine. Weight and balance matter more than you think. A detector that is heavy or nose‑heavy will tire you out quickly. Look for a model that weighs roughly around three pounds with the standard coil, and try to hold one at a store if possible. Make sure the arm cuff is comfortable and the control box is well‑balanced. Finally, consider waterproofing. A waterproof search coil (not necessarily the entire detector) lets you hunt in light rain or shallow freshwater without worry. Fully waterproof detectors let you wade or snorkel, but that feature raises the price significantly.

VLF vs pulse induction: which is right for your hunting?

If you plan to hunt dry land parks, fields, and old homesteads, a VLF detector is almost always the better choice. You get accurate target ID, the ability to reject iron, and sensitivity to small gold rings and thin coins. VLF units also tend to be quieter in clean ground and easier for beginners to learn. Pulse induction detectors shine on saltwater beaches and in highly mineralized soil that would make a VLF machine unstable. They push through salt and black sand to find deep targets, but they typically offer no target ID (just a “dig me” tone) and less ability to discriminate out trash. Many serious beach hunters own a PI as a second machine. There are also multi‑frequency VLF detectors that handle both fresh and salt water well, blurring the line. If you only hunt beaches occasionally, a good multi‑frequency VLF may be enough. If you are a dedicated wet‑sand or water hunter, a pulse‑induction or a specialized multi‑frequency PI is worth the extra money.

How important is a waterproof detector?

It depends entirely on where you swing your coil. If you only hunt dry land, a waterproof control box is a nice convenience but not essential. A rain‑resistant unit with a waterproof coil will survive light drizzle and morning dew. If you plan to wade into the surf, hunt rivers, or search shallow lakes, you need a fully waterproof detector rated to at least 3 to 10 feet. Many mid‑range and high‑end models now come fully submersible. Keep in mind that a waterproof detector also lets you rinse the whole machine under a tap after a saltwater hunt, which extends its life. For beach hunters, the trade‑off is price. Fully waterproof machines cost more and sometimes have fewer features because the control housing has less room for advanced settings. But if you often find yourself in the water, it is the only way to go.

What accessories should I budget for?

A good pair of headphones is the first upgrade. They let you hear faint signals and improve battery life by not using the built‑in speaker. Wired or wireless, any pair that fits comfortably under your sun hat will help. A pinpointer is almost essential for recovering targets quickly. Rather than digging a huge hole, a handheld pinpointer narrows the target’s location to an inch or two. Popular brands like Garrett and Minelab make reliable models. Budget for this early. A digging tool that suits your ground is next. On turf, a narrow garden trowel or a specially‑made “lesche” style digger works well. In sand, a simple sand scoop saves your back. For rough soil, a heavy‑duty pick may be needed. Finally, consider a lightweight carrying bag or backpack to keep your detector, coil covers, extra batteries, and finds organized. Many people also add a coil cover to protect the bottom of the search coil from scrapes.
