High-resolution iron discrimination — use touchpads to set iron discrimination at one of 40 levels for the precise ability to separate good targets from trash. It’s easy to get bogged down in specifics of coils and iron discrimination if you’re looking for the best metal detector, but don’t forget these basic bits of information. What about the all essential ground balancing you ask? Well, the AT Pro has manual and automatic ground balancing – the best of both worlds in fact. For many treasure hunters with standard binary audio, junk bottle caps and flat steel washers appear to be good targets. They produce a high-tone target response. This happens because the shape of the bottle cap and the flat surface resemble a coin which fools the detector. With the AT Gold's Tone Roll Audio, however, the bottle cap will produce a very unique response with multiple audio tones. As shown in the illustration above, the bottle cap will yield a distinctive low/high/low response as compared to the coin's unique high-only audio response. However, these settings might not be effective in keeping metals with high conductivity such as pull tabs and foil away.

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.

Understanding the Garrett AT Pro Double D Search Coil Design:

It can be challenging to hunt for valuables in areas that are laden with trash. In such areas, a detector can often end up targeting small items like nails, bottle caps, and more which can consume a major chunk of your time. For those who want to learn more about the target, use the Pro Mode. The ability to hear a target’s size and depth through Proportional Audio is only one of the advantages of working in Pro Mode. Pro Mode’s more sophisticated audio features are intended for more experienced users who want to hear the actual signature of targets rather than the simplified target response available in STD Mode. Notch Discrimination Iron discrimination may be the first to try as it helps you weed out Coke cans and nails. Waterproofing But when a coin shooter hits a questionable signal and can’t decide whether to dig, they can flip on Iron Audio and instantly determine if any iron exists in the target. This feature saves you from digging trash so you can spend more time digging good targets. Automatic & manual ground balance If you are looking for an all-terrain metal detector that is of mid-price range then the AT Pro is definitely for you, the AT in the name stands for all-terrain so it’s clear Garrett focused on making sure they lived up to the name. Many people have spoken very highly about how great the machine performs no matter the condition. The fact it is waterproof also does it for me, this will help you get to places that other detectorists haven’t been! I haven’t myself used the Garrett AT Pro however this is top of my list when I upgrade.

Ground Balance: Using this on its own will auto ground balance, but if used with notch disc can be used to manually set the ground balance.If I’m heading out for a day’s happy hunting and want to maximize my chances of a find, I grab the Pro. If I’m not sure exactly what terrain I’ll encounter, this is the machine for me. The Garrett AT Pro’s Iron Audio system works alongside its notch discrimination feature. Notch discrimination is a must-have if you’re serious about finding valuable items. Garrett AT Pro is an All-Purpose, All-Terrain metal detector for detectorists with medium level of skill. The device is versatile and diverse, it has a bunch of compatible accessories both by Garrett and by other brands, which makes it even more universal in use. The whole thing is powered by 4 AA batteries, and has two years warranty by the manufacturer. This metal detector seems to be suitable for gaining experience, growing metal detecting skills from medium to expert level. Control Box Digital target ID — the 0 to 99 target identification scale offers increased ability to distinguish one target's conductivity from another.

One person even described it as a “Silver finding beast” and would highly recommend you buy the Garrett AT Pro Let us take a look at what we have found out. Design and Appearance of the Garrett AT Pro There is no way to adjust the threshold and volume of the tone. The legend on top of the screen is barely visible in some conditions.Although people have said it isn’t by any means 100% accurate it does work to a degree and gives you a higher level of confidence to what is located on the ground. It would be a good idea when you begin with the AT Pro to document the ID numbers next to what the find was. It has also been used a lot by other detectorists to locate missing items, let’s say for example a lady loses one of her earrings. Manual ground balance — Allows you to manually adjust the detector's ground balance to reduce the detrimental effects of ground mineralization.

The Tone Roll Audio provides you with the most audible target information and will help classify targets, particularly iron targets. Normal metal detectors with standard binary audio, produce a single target sound based upon the target's strongest signal. With Tone Roll Audio, you are given a variance of target tones as the search coil nears, passes over and then departs from the target. By listening to these varying phases of audio sounds, you can achieve better overall target analysis. AT stand for All Terrain which gives you a good idea about its capabilities. Having used one, I can say this is true – almost.The Garrett AT PRO is ideal for use on the beach, especially due to the submersible design. You can use the metal detector in bodies of water that measures up to ten feet in depth. 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 AT Pro will effectively search in all soils, sands, freshwater, and trashy areas, but it won’t perform well in salt water or on wet sand. What Will The Garrett AT Pro Find?
