Not all ground conditions are the same, which is why you’ll find metal detectors available to explore every type of environment. Metal detectors are electronic devices that feature a large coil of wire, or transmit coil, and a second coil of wire, the receive coil, that indicate buried metal via a speaker. The more conductive the ground (eg, wet from rain, salty soils, ferruginous soils) the shallower the detection range. A budget detector is capable of alerting you to a gold ring and may end up paying for itself, but only if you can understand what it’s saying to you. This is not an easy task, and if you don’t go where gold is known it’s nigh on impossible.

If you set the audio to a high pitch for gold and bass for silver you don’t even have to look at the screen, just keep your eyes applied to the soil.
While either PI or multi-frequency will work, there are some pros and cons to each. Most all round machines will do just fine for relic hunting. You’ll also want to avoid a pulse induction machine – or PI for short. Frequency and depth have an inverse relationship, so the higher you get, the less depth you’ll get on coin-sized targets. While most machines are designed as all around detectors for coin, jewelry, and relics, there are also specialty machines for different uses.
