3 product ratings 3 product ratings – Garrett AT Pro Metal Detector with MS-2 Headphones and Pro-Pointer AT, USA Ver. Michael adjusting an early Garrett Metal Detector in North Carolina at the first treasure hunt we ever displayed our products at back in 1985. Whether you’re looking for your first hobby metal detector or want a state-of-the-art model for serious treasure hunting, you can find the best metal detector for the job at An entry level metal detector will pick up all of these metals, but if you want to find a certain type of object, say gold, you’re more likely to find it with a specialized detector that runs a high frequency. It has a large 7 x 10-inch search coil for better depth and discrimination and runs on an 8kHz frequency that you can adjust.

If you’re looking for exciting treasure over trash turn the adjustable sensitivity down. All metal will obviously detect everything, full discrimination will ignore low-value targets like iron, and tone discrimination will emit a different tone for each find. Would you consider The Garrett GTI2500 to be an out-dated machine? I am looking for Gold flakes/small nuggets in a very mineralized iron ore area and quartz veins also to search in shallow streams.

Garrett Pro Pointer AT – The Waterproof AT Pro-Pointer combines performance with sleek design to assist in pinpointing those hard-to-find targets. Garrett Pro Pointer AT Waterproof Pinpointer bundle with Pro Pointer AT and a 9v battery.

Chapter 3: Metal Detection: This useful (though slightly dated) 1999 review comes from a US Department of Justice report on “The Appropriate and Effective Use of Security Technologies in US Schools,” and includes a look at walk-through detectors, hand-held metal detectors, and X-ray baggage scanners. The orientation of the object: objects buried flat are generally easier to find than ones buried with their ends facing downward, partly because that creates a bigger target area but also because it makes the buried object more effective at sending its signal back to the detector. The size, shape, and type of the buried metal object: bigger things are easier to locate at depth than small ones. If you sweep the detector above a metal object (such as this old gray spanner), the magnetic field penetrates right through it.

You’ll spend less time digging for junk, and more time digging for treasure. There’s an adjustable sensitivity so you can fine-tune the machine to suit the soil conditions and your preferences. Other menu controls include a target depth indicator which shows how deep to dig for the target, and a battery level indicator so you’ no caught short. The Fisher F22 has a 9-inch search coil that’s waterproof and a superfast re-tune speed.

The age of the object: things that have been buried a long time are more likely to have oxidized or corroded, making them harder to find. The magnetic field makes electricity flow around the receiver coil metaldetectorshub and up into the receiver circuit (blue) at the top, making a loudspeaker buzz and alerting you you’ve found something. The magnetic field cuts through the receiver coil (blue) moving about up above it.

Ploughed field is a boost setting that gets much more depth and is good at locating hordes. There are some excellent pre-set programs on this machine for the relic hunter. 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. Their new Ace 400 detector sits pretty at the top of the beginner range while being solid enough for experienced hunters.  The 400 is an upgrade on the excellent ACE 350 which is now discontinued.

The only real advantage it has over the DD (in my opinion) is that it can be easier to pinpoint your target. There are a few points you should consider when choosing a coil.

Your metal detector will pick up tiny traces of mineralized iron and report it as a find. 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.

8 kHz means you’ll pick up pretty much everything if you listen closely, but uping the kHz finds objects with greater conductivity such as gold. This machine is simple yet informative and a great place to begin. The Garret Ace 300 is recommended everywhere as ‘hands-down’, one of the best beginner metal detectors. 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.
