This detector offers all the features an advanced treasure hunter could want but is easy-to-use right out of the box. The GOLD metaldetectorshub MONSTER 1000 turns beginners into experts with fully automatic operation in an easy-to-use, high performance detector.

We scored metal detectors with DD search coils higher because their search fields are shaped like a blade. A concentric coil emits a cone-shaped search field, which means the search field narrows to a point. A few of the metal detectors we had would experience interference when in close proximity to each other, so just to be on the safe side we only had one on at a time during testing. We know you’re not supposed to use metal detectors inside because other machinery can interfere with readouts, but we grounded each machine and made sure it wasn’t picking up any extraneous metal. If you’re worried about arm fatigue while you’re treasure hunting, the Tesoro Mojave is the best choice.

A pulse induction machine finds deeper, smaller objects than VLF detectors and they’re programmed to ignore ground minerals. Depending on your machine, it may narrow the search area down to a foot or two.

So many aspects affect how deeply a detector can sense metal that it’s impossible to give a straight answer. Low-frequency machines at 2-4 kHz are best for deep-seeking everything, mid frequency 5-12 kHz for relics, jewelry and coins, and higher frequencies for gold. High-frequency kHz has shorter wavelengths and finds smaller targets with less conductivity, such as nuggets and flakes of gold. A machine with ground balancing detects what type of ground you’re on, and eliminates the unwanted minerals in response.

The worst mineral for metal detectorists is iron because it’s conductive and sets off your machine. This is because each machine behaves differently, and over time you’ll learn which settings are best for say coins, whereas another setting is better for dropped rings. Rented metal detectors are generally good quality brands so you’ll have a better time of it.

If you’re relic hunting, take a note of the exact place because a historical record is helpful to archaeologists should that relic prove interesting or unusual. When that glorious ‘beep’ calls out, it’s time to pinpoint exactly where the signal is coming from. Some detectors give out different tones when they hit iron or gold for example. It needs to be sufficiently close to the soil or sand so the magnetic field can penetrate, but not so low that you bash the sensitive coil on stones and clods of earth. Sweep the machine side to side in front of your feet.

We tested each metal detector’s performance finding iron nails, aluminum pull-tabs, pennies, nickels, dimes, quarters and precious metals. Metal detecting is not a hobby for the impatient that need immediate results. Pulse induction is a speciality machine for the serious beach and salt water detectorists. If you want to buy only one machine, and intend to hunt on land and dry sands, choose multi-frequency as it will have a better discrimination range. This may sound like a daft question to some, but I’ve found that proper kit makes metal detecting a more pleasant experience, but there’s no uniform, feel free to wear a mankini if you prefer.

If your detector is singing like Beyonce check there are no power lines nearby. But hold up, ground mineralization isn’t the only interference issue detectors need to deal with. This is what detectorists are talking about when they complain about ground mineralization.
