When using discrimination, you have to be very careful. Most of the time, targets are greater in size or they vary in terms of composition. It also comes with a pre-set ‘coin’ mode which eliminates foil, pull-tabs, and foils automatically. This mode is suitable for beginners who wish to go coin hunting. The AT Pro has a fully adjustable frequency setting. At its highest setting, it can produce a 15 kHz signal. This is considerably higher than most VLF units on the market, making it a great option for finding objects with lower conductivity levels. Pro Mode Audio Both experienced hobbyists and newcomers can benefit much from this metal detector. It is simple to learn how to use. Priced mid-range the Pro holds its own against others in Garrett’s AT range – in fact, it’s the benchmark.

I’ve found it impossible to detect without ground balancing of some kind, and on those days when you feel a bit lazy or under the weather, auto ground balancing is a stress-saver.The important components are all sealed. Even the exposed metals are treated to prevent oxidation, which is a huge plus. The metal detector has some other features that assist you when you’re metal detecting underwater, but we’ll get into those in a bit. VLF Detection The problem with ground mineralization is that it affects the overall magnetism of the soil. Those trace metals can trip up cheaper detectors, rending them useless. You’re in the right place. Let’s take a close look at one of Garrett’s most popular metal detectors.

All metal detectors detect gold; the only question is can the machine handle the types of environments and terrains where gold is most typically found? (i.e., high levels of mineralization).Here the notch discrimination comes in handy. You can choose to accept or reject from the 12 different discrimination segments. high Recovery Speed – the higher the Recovery Speed, the clearer signals the metal detector will give for every separate target located underground, when there are several items placed close to each other. If the Recovery Speed is not high enough, trash targets tend to mask responses from valuable targets, but in Garrett AT Pro, this is not the case. With a built-in ground balance system, the AT Pro metal detector is capable of overlooking those minerals. It reduces ground noise so that you can focus on finding objects of value.

The control box has 8 buttons, making it easy to navigate and control. These buttons are as follows:Overall, the Garrett AT Pro metal detector is a very flexible device. There are several parameters you can adjust to get the perfect performance for your environment. Proportional audio on Pro mode sings a variety of tones (all non-screeching) when it discovers a target. It’s your job to figure out what these audio tones mean in terms of the target shape, conductivity, and depth. Use the clear instruction manual to save time.
