The CW-20 is an all-purpose high performance security metal detector at an economical price. Minelab’s new 6 inch coil for the Equinox series is ideal for detecting on difficult terrain and restricted spaces.

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. Note that you do NOT need a specialty machine if you’re hunting on the dry sand of a salt water beach. One thing you want to make sure of here is that you do not buy a machine with too high frequency – i.e., one designed for gold prospecting (you can read our guide here on the best metal detectors for gold nuggets). You’d like to get into metal detecting but aren’t sure which detector to go with.

Always fill the search hole cleanly and remove any mess before moving on, but before you carry on your merry way, take a really slow and close sweep of the surrounding area. 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.

Fully HACCP and GMP compliant, CEIA Metal Detectors are ISO 9001 certified and constructed of EC and FDA approved materials. CEIA’s approach to the development of its detectors has been to employ the most advanced electronic and mechanical technologies: Surface Mount Technology (SMT), digital signal analysis, software upgrades capability and the use of high-quality materials. A deflector can be mounted at the end of the conveyor, or metal can be removed manually. You pick the technology and the configuration best suited to your particular inputs, flows and processing configurations.

Low frequencies typically give more depth on large targets than high frequencies, which are usually more sensitive my company to small targets. Renowned ground balancing capability for the best results in all kinds of soil.

You can also use the same machine for all of your hunting as opposed to the PI where you should only really use it for beach hunting. The benefit to using a multi-frequency detector in salt water is that you can discriminate out unwanted targets.

In fact, if you get fed up with coin hunting you can use this machine for everything else with a few tweaks. The Spectra V3i is coveted by all metal detectorists – it’s the Ferrari of the detecting world. The only useful missing feature that really matters on this machine is manual ground balancing, but that’s not a show stopper – you can use its automatic one instead.

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.

I want to thank you for taking the time to to share your knowledge and experience with with us. This one may sound obvious, but you’d be surprised how many people purchase a detector ‘completely blind’, so to speak, having never read a single review on the machine. Some folks think it’s silly to own a machine without a screen, while others are just fine with a Tesoro-type detector that features only knobs.
