Highly mineralized soils tend to give out lots of signals that metal detectors love to pick up. This is a great feature that will save you time and aggravation. Turn it up, and the detector will alert you to everything – sometimes even minerals in the soil. Especially as it has the coveted autotrac ground balance – more on that later.
The magnetic field cuts through the receiver coil (blue) moving about up above it. When electricity flows through the transmitter coil, it creates a magnetic field all around it. If you’ve ever made an electromagnet by wrapping a coil of wire around a nail and hooking it up to a battery, you’ll know that magnetism and electricity are like an old married couple: whenever you find one, you’ll always find the other, not very far away.

Stick to the dry sand and your current detector is fine, nothing special is needed. You’re most likely to find these at the beach where cold fingers shrink and undressing pulls off necklaces and bracelets. Every squeak and beep is a signal telling you something metal lies beneath the soil or sand, but maybe there’s something specific you want to find. Each time you hear the beep it could be ‘the big one’. Cold fingers, slippery sun lotion, water action, and hot sweaty sports can lead to objects working loose or falling from pockets.
At Bill Jackson’s we carry metal detectors by White’s Electronics and Minelab. If the screener, through use of the detector or otherwise, discovers or has reason to believe that a weapon is present, he or she shall promptly report that information to a detail officer. Activities may not occur in areas where someone holds a park reservation permit or during special events in the park. This list may be amended at any time by the Director of Parks and Recreation. The plug-in-and-go design ensures consistent voltages, which optimizes sensitivities unlike batter-operated unites which lose sensitivity.
Metal detecting is popular because although it’s seen as a solitary pursuit it can also be social. It might help especially when it comes to specifics such as gold nugget hunting, but an entry-level machine will do you proud until you want to upgrade, and they go for a good price on certain auction sites.
When you are ready to dig the depth indicator shows how far down you need to go. Target ID will provide you with a numerical scale from 0-99. The digital target ID function is really handy and not always featured on beginner models.
Multi-frequency (MF) detectors are typically machines that go for over $1,000 and most commonly found in the high-end Minelab detectors. There are a few different technologies you should familiarize yourself with when choosing which detector to buy. Depending on how old the child is, you might want to start with a detector that’s not super heavy. Most of these machines will be PI and should be used in areas where gold is known to be found.
When it comes to choosing a detector to help with hunting for gold, one of the better models happens to be the Garrett ATX. The Garrett Ace 150 is the base entry model of the Ace range, this is ideal for beginners who have no prior experience in metal detecting. Some of these features include; adjustable sensitivity and depth settings, pinpointing, custom notch discrimination, 6.5×9″ ACE coil. We are a Certified dealer in all major brands, with over 20+ years experience and many finds, Whether you are looking at Metal detectors for gold nuggets or treasure hunting we are able to direct you with training and the right equipment.
In general, the lower the frequency, the deeper you can detect. The detectability of the anomaly depends, amongst other things, on the power of the unit and the general conductivity of the ground over which you are working. The size of the phase shift and amplitude (the “anomaly”) depends on the click to read quality of the conductor, it’s size, and it’s depth. It’s the thrill of the hunt that keeps us all searching, and you get a good time feeling whether you spend $200 or $2000. Lots of folks are excited at the thought of prospecting for gold nuggets and wiping out their mortgage in one fell swoop.
Advanced detection coil design, combined with proven Safeline software, ensures metal contaminants as small as 0.3mm in diameter can be detected and rejected. Fully integrated pharmaceutical metal detector solutions for inspection of tablets, capsules, powders and granules. Safeline Gravity Fall metal detector systems inspect bulk, free falling fine powdered and granular products in food production and non-food applications.
While large coils get better depth, they also see more of the ground which means your detector has to process more signals in mineralized soil which can lead to very bad falsing, poor target ID and missed targets. Click here to read my in-depth guide to choosing the best metal detector for kids. The only real con to using a multi-frequency machine on the beach is that you won’t get the type of depth you would with a PI – although it will still be excellent. If hunting in the wet sand, surf or water, you’ll need a machine that’s either PI or multi-frequency.
Carrying a detector for hours can tire you out before you’re ready to head home. Once you have a detector there’s not much else required, but some extra bits and pieces can make you comfortable and help with the tricky aspects. Salt from the ocean water and surf spray can also cause problems with components. Wet sand is mixed with ‘black sand’ and black sand is mixed with iron and other minerals that can trick your detector into springing a signal. However, venturing onto the wet sand or into salt water is another kettle of fish.
