Frequency is the invisible spec that separates a bargain detector from a serious one. It determines which metals your machine sees best and how it copes with wet sand, mineralized soil, and buried trash.
- Single Frequency operation is the standard on entry-level and mid-range detectors. It works well on coins and jewelry in normal soil and keeps the price down, though performance narrows in salt water or heavily mineralized ground.
- Selectable Frequency lets you switch between two or more frequencies, low for large deep silver and high for small gold and thin chains. It's a flexible middle ground at a reasonable cost.
- Multi-Frequency transmits several frequencies at once and analyzes them together. It handles salt beaches, mineralized dirt, and mixed targets far better than anything else, which is why it dominates the high end.
- Pulse Induction ignores ground mineralization almost entirely and punches extremely deep, favored for diving, black sand beaches, and gold prospecting. The tradeoff is minimal target discrimination, so you dig everything.
For inland parks and fields, single or selectable frequency is plenty. If salt-water beaches or gold country are in your plans, budget for multi-frequency or pulse induction and skip the upgrade cycle.
Most people are best served spending somewhere in the low-to-mid hundreds for a first real metal detector. Under about fifty dollars you're usually buying a toy that only reaches a few inches deep and beeps at everything, which tends to kill enthusiasm quickly. A solid beginner or entry-level hobbyist machine from an established brand will find actual coins and jewelry at usable depth, and it will still be worth something if you decide to upgrade or sell later.

Pinpointers are almost always sold separately, though some detectors are bundled with one as a kit. Most full-size detectors have a built-in pinpoint mode that narrows the signal, but a handheld pinpointer probe finds the exact object inside the hole you've already dug. Nearly every experienced hunter considers one essential because it saves an enormous amount of digging time and keeps holes small, so budget for it either as part of a kit or as your first accessory.

It depends entirely on where you plan to hunt. Almost every detector has a waterproof coil, which is all you need for dry sand, parks, fields, and wading a few inches at the shoreline. A fully submersible detector with a sealed control box costs considerably more and only makes sense if you'll be wading deep, snorkeling, or diving. Read listings carefully, since "waterproof coil" and "waterproof detector" are very different things.

Yes, but the stock coil on most detectors is sized well for general use. Coils in the nine to eleven inch range balance depth, ground coverage, and the ability to separate nearby targets, which suits nearly every hunting situation. Smaller coils work better in trashy ground and tight spaces, while larger coils cover more ground and reach deeper but miss small items. Check whether the detector accepts aftermarket coils so you can add a small one later instead of buying a second machine.

Single frequency is perfectly capable for inland hunting in parks, yards, and fields, and it keeps the price much lower. Multi-frequency machines cost significantly more but handle salt water, wet sand, and mineralized soil far better while identifying mixed targets more accurately. If salt beaches or gold prospecting are in your plans, paying for multi-frequency up front usually saves you from buying twice.

Online-first budget brands can be a reasonable choice for casual use, kids, or simply testing whether you enjoy the hobby. They often list impressive feature lists at low prices, but build quality, waterproof seals, warranty support, and parts availability are inconsistent. If you expect to hunt regularly, an established brand will perform better, last longer, and hold resale value. For a gift or occasional backyard use, a budget model gets the job done without much financial risk.
