Some metal detectors are light as a feather while others are built like bricks and can be quite heavy. For those who like the best of both worlds, that may be a detector worth looking into. Alternatively, if you’re looking to cover large, open areas like beaches and farm fields, a larger coil might be a better option. There are a few points you should consider when choosing a coil. They’re also great for doing both saltwater and all around detecting without having to buy two machines.

You’ll want it with you when you’re scanning the beach for treasure. Our focus will be on consumer metal detectors, but most of the information also applies to mounted detection systems, like the ones used in airports, as well as handheld security scanners. Multi-simultaneous frequency technology and digital signal processing ensure optimum detection across the entire tunnel or contact area. Regardless of whether you manufacture or process food, plastics or other products, our tunnel and flat metal detectors readily integrate into all production lines for piece and bulk goods. Lower Scale – The lower horizontal scale, or Notch Discrimination Scale, indicates the discrimination pattern where the detector will or will not produce an audible signal when a target is located.

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. A smaller coil would see less of the ground, process less ground signals and allow you to increase your sensitivity to the point where you could be getting the same depth as you would with the larger coil in neutral ground.

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.

Safeguard your products from metal contaminants with a cost-effective metal detector for conveyor and drop-through applications. Protect your brand in a drop through pipeline or combination check weighing application with a compact, high-performance metal detector.

There’s also a handy depth indicator so you’ll know how far to dig, and the multi-tone audio will let you know what you’ve found without consulting the screen, which is handy in bright daylight. The ACE400 is a solid all-round detector you’ll love to play with.

Smart sensitivity adjustment and a high level of resistance to interference help to prevent erroneous activation. More information on how Sesotec metal detectors work is available here. They detect metallic contaminants, regardless of the metal type and whether the contaminant is exposed or embedded in the product. Tunnel metal detectors enclose a conveyor belt, while flat metal detectors are attached underneath conveyor belts or chutes.

First, ground conditions and mineralization play a huge role in which size coil to use. Another thing to consider is the stock coil that comes with your detector. Multi-frequency (MF) detectors are typically machines that go for over $1,000 and most commonly found in the high-end Minelab detectors. These machines will punch through ground minerals like salt and iron and will report on all metal objects without the ability to discriminate. Pulse induction (PI) is a technology used in specialty machines for areas of high mineralization – i.e., salt water beaches and gold country.

Eriez’ MetAlarm Model HH-10 Handheld Metal Detector is designed to locate the exact position of small pieces of unwanted tramp metal. Eriez’ Model PL2 MetAlarm Metal detector has been specifically developed for direct attachment to lightweight conveyors used to feed granulators with tops and tails, sprues, etc., from molding machines of all types.

Robust, hygienic housing (up to protection class IP66 / 69K) enables easy cleaning. Continue  The AuditCheck function tests and documents detection in an automated process.
