For those who want to be fully immersed in this hobby, then they should look for a metal detector that can handle the rough terrain and the handling. If the metal detector is to be used on rare occasions, then a normal one will serve the purpose. All purpose metal detectors also have water proof material and they can be used to search the edges of rivers or lakes for lost coins and jewellery.

Anything below that isn’t really considered a detector – it’s considered a toy. What makes one detector better than another (like cars) is the additional features and enhancements.

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. These are signal frequency machines used for coin, jewelry, and relic hunting.

In the past, the main reason for food producers to choose metal detector over an X-ray system was cost-related. When the food safety standards started to become more common, the metal detectors were the only systems to ensure the products safety for a long period of time. Adaptable for all target types and ground conditions makes the 800 a true turn and go metal detector. The EQUINOX 800 Metal Detector with Multi-IQ technology, redefines all-purpose detecting for beginners to serious enthusiasts. Improve operational efficiency and decrease costs with a uniquely-designed heavy-duty metal detector built for the most demanding food processing and packaging environments.

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.

Highest sensitivity and reliability with small insertion space for maximum product quality and brand protection. Choose from a range of high-speed reject devices designed for specific applications. Throat-style her comment is here that can be integrated with Vertical Form Fill and Seal processes and equipment to inspect free-falling product in-flight. All our metal detectors come with a 2 year guarantee on parts and labour (excluding batteries) and our Customer Service is second to none.

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.

But you’re depth will be severely limited to the point where it’s not even worth it to detect. Most all round machines will do just fine for relic hunting. You’ll also want to avoid a pulse induction machine – or PI for short.

Beach hunting can be as simple or as complicated as one wishes to make it. Beach combing is hunting for lost coins or jewelry on a beach. Larger portable metal detectors are used by archaeologists and treasure hunters to locate metallic items, such as jewelry, coins, bullets, and other various artifacts buried beneath the surface. I am looking for Gold flakes/small nuggets in a very mineralized iron ore area and quartz veins also to search in shallow streams.

Using maximum sensitivity means ALL metal signals will ring out, including minerals and trash. Experienced detectorists have a range of coils and chose one to suit the area they want to search. An elliptical coil works in just the same way, albeit covers less ground in one swing, but it can reach into small, awkward spaces.
