When you’ve made a proper sweep of your yard offer metal-detecting services to friends and family. That’s because you need to remove some sensitivity from your detector. 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.
Each metal detector took a little getting used to, but we persevered. You can switch between eight sensitivity levels and get between 20 and 25 hours of treasure hunting from one 9-volt battery. One of our technicians brought in a similar piece from another metal detector, and we were able to test. We have to include the fact that this metal detector arrived at our lab missing a piece of the arm. We tested each metal detector’s performance finding iron nails, aluminum pull-tabs, pennies, nickels, dimes, quarters and precious metals.
Dip and drag in through sand and water to grab a target before it drifts out to sea. It’s possible to buy ‘metal-detecting’ trowels that are longer and thinner but I’ve never bought one. Best places to search on a beach are the towel line where beachgoers drop their belongings and dips of sand close to the waterline or near a sandbar. There’s something very soothing about combining wave action with the swing of your detector – plus piles of treasure that people leave behind mean you’re likely to find something.
There are others that combine nugget and relic hunting such as Whites MXT Tracker which goes for $800 and the Tesoro Lobo SuperTRAQ which retails at $700. Although the choices are limited, there are good metal detectors that serve many different functions.
It might sound obvious but metal is what you’ll find with a metal detector. Beaches are great places for metal detecting because beaches are regularly and actively used by the public. Taking a long slow sweep of your yard with a metal detector is a great place to begin. A kilohertz or a kHz is the number of waves a metal detector can send into the soil.
Basic types include industrial and security, general prospecting, gold prospecting, underwater and salt beach, cache hunting and deep searching. The simple rule for trying to find the best metal detector for beginners is to buy the best you can afford and really get to know how it works. Metal detecting is a zoning out solitary hobby and a social one – it’s whatever you want to make of it.
The guy in England who received a metal detector for Christmas, then took it into a nearby field and promptly found a horde of Viking gold for example, but for the rest of us finding targets is a slow process. If your metal detector doesn’t pinpoint, investing in a separate pinpointer saves digging time and my website much frustration. If you have a gold detector then you’ll find gold at a deeper depth than a standard machine. Gold is one of those metals that benefits from a specialized gold-detecting machine that works on a higher frequency. Getting the sensitivity right can make or break a newbie metal detector.
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’. Renting a metal detector also gives you the opportunity to try out different brands. It’s best to move slowly and steadily so the coil has time to register a target. 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.
