It was the time he reunited an old high school class ring with its owner —  a Cassville woman — whom he located through an internet search. The machine dated back to the 1960s when burgeoning hobbyists discovered they could be used to do cool things, like prospect for gold. Another thing that you may want to consider when you shop for metal detectors online is the frequency range.

Renting a metal detector also gives you the opportunity to try out different brands. When the magnetic field is placed over a metal object the current flows through the metal object and back into the detector activating the receiver coil. Control Box – the metal detector’s brain is located here alongside the power source.

Yes, you might lose some depth, but you’re more likely to find something of interest. You need adjustable sensitivity to pick out the good stuff and not go insane with constant false signals. Experienced detectorists have a range of coils and chose one to suit the area they want to search. The standard 8-inch coil is an all-purpose coil that performs well across the board and is best for a beginner.

Michael adjusting an early Garrett Metal Detector in North Carolina at the first treasure hunt we ever displayed our products at back in 1985. Our metal detector store features an extensive selection of today’s top brand-name hobby why not try these out, as well as advanced detection equipment for security, industrial and marine applications. A Metal Detector that i can use to find everything on water and land. It can tell us things like depth of the target, what it thinks the target is, where our sensitivity and discrimination are set, battery life and many other things, depending on the detector.

Salt from the ocean water and surf spray can also cause problems with components. However, venturing onto the wet sand or into salt water is another kettle of fish.

I always say your choice of metal detector is the best you can reasonably afford. High frequency simply provides better gold detection and a better chance of paying off your mortgage early. Whilst those machines can and do pick up gold, they aren’t as sensitive as a high-frequency machine, and you risk leaving that elusive nugget behind for someone else.

You may also want to get a machine that’s relatively easy to use with not a lot of settings. ​Click here to read our complete guide on the best metal detectors for gold. The only factors you need to consider here is that you get a fully submersible machine with good discrimination – that’s really it. The major benefit to PI machines is their superior depth in highly mineralized areas like salt water beaches. Frequency and depth have an inverse relationship, so the higher you get, the less depth you’ll get on coin-sized targets.

If you’re on highly mineralized ground, you’ll know because the detector will sound like a firework – turn down the sensitivity. That metal detector will end up flying off a cliff because it’s uncontrollable and really, really annoying. In highly mineralized soils detecting can be almost impossible because your machine is barraged with iron particles and screaming its head off with excitement. The worst mineral for metal detectorists is iron because it’s conductive and sets off your machine. Although user manuals give a good indication of the best frequencies, and some models have a ‘coin’ or ‘gold’ setting, it’s no comparison to learning all the squeaks and blips of your own machine – ‘Hector the Detector’.

Rented metal detectors are generally good quality brands so you’ll have a better time of it. Some detectors give out different tones when they hit iron or gold for example. Practice in your yard first, it’s helpful if you bury different objects such as trash, gold, and coins to figure out the best technique for your machine.

Still, it makes sense to buy an entry-level machine until you are sure this is the hobby for you. The basics haven’t changed over time and taking potluck is all part of the game.
