Garrett AT Pro Features
Garrett AT Pro offers a set of features and functions that are handy and effective for almost all types of search. While this metal detector cannot be considered the top technology nowadays, when there are so many other decent machines by other brands, AT Pro is still equipped with an impressive toolkit that will provide a metal detectorist with generally everything needed for successful search:
- waterproof up to 10 feet – AT Pro is not just protected, it can be used for some diving, but not deeper than 10 feet, otherwise leaks are possible. However, 10 feet depth is already more than many other metal detectors in the niche can offer. This water protection range gives enough freedom of movement for most treasure hunters.
- DD coil – DD coil configuration is considered one of the most versatile and universal in usage. So, the metal detectorist can start with the default coil that will serve well in most locations, and then upgrade with another compatible coil if such need arises
- frequency shift – this feature means that, when any other potential source of electromagnetic interference may be present nearby, and cause noise and false signals, the machine allows to adjust the operating frequency to fall out of resonance. This feature is even more important in a metal detector with only one operating frequency.
- VDI (Target ID) – Visual Discrimination Indicator. This is the indicator scale that shows numeric interpretation of what is supposed to be underground, based on the electromagnetic response given by the target. Visual Indicator always makes it easier to interpret the signal.
- Pinpoint mode – this feature is of great help in metal detecting, because it allows to define that there is definitely a target down there, where the target is, exactly. While Pinpoint mode cannot replace the Pinpointer tool in efficiency, it still makes detecting more comprehensive.
- Ground Balance – AT Pro offers both Manual and Automatic Ground Balance. This makes detecting a bit easier for beginner level detectorists, but also offers more flexibility in tuning the machine if the user already has enough experience.
- Iron Audio – usually the feature of Discrimination allows the user to tell a good target from the bad one, however, having a separate Iron Audio mode makes this task even easier.
- 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.
Iron Audio
Most often, signals from iron targets are filtered with the help of the Discrimination feature. When the Discrimination settings are tuned to dicriminate ferrous targets, these targets are either ignored completely by the metal detector, or give specific sounds that help the user understand that the item is ferrous.
With AT Pro by Garrett, double-checking ferrous items is even easier. When you switch on the Iron Audio feature, the metal detector will show you silenced (normally discriminated), preventing you from digging doubtful targets, but this is not all. Iron Audio actually adjusts the tones, and in addition to low tone meaning ferrous item, the machine is able to catch the response of other items nearby, if any, and give higher tones for these items. So, the user can both avoid ferrous items, and distinguish potentially valuable targets better.
Freshwater\Saltwater Use
In contrast to some other metal detectors which are waterproof and fit for deeper underwater search, Garrett AT Pro is fit not only for freshwater use. Due to its high quality 40 segments Discrimination, and also its outstanding Auto Ground Balance feature, this metal detector shows decent performance in saltwater, too.
Garrett AT Pro Coils
The search coil provided in the basic kit is the elliptic DD type sized 8.5×11 inches. This comparatively small coil’s configuration makes it versatile and maneuverable in many different locations. The size best fits for smaller and not very deep targets like coins, jewelry, rings, etc, making it the best coil for Garrett AT Pro. However, there are several additional compatible coils for this metal detector, enabling the detectorist to optimize their search virtually under any conditions.
The list of compatible coils includes waterproof Garrett 5 x 8 inches DD PROformance Search Coil, the largest among Garrett coils compatible with AT Pro Garrett concentric 9 x 12 inches PROformance Search Coil with faster recovery speed and bigger areas to be covered, small and perfect for highly littered locations Garrett 4.5 inches Super Sniper Search Coil. There are also compatible coils by other brands, including those by NEL and Cors.
Garrett AT Pro Settings
Considering the number of functional buttons on the Control Panel, tuning AT Pro may seem somewhat intimidating. However, there are some basic things that are simple and comprehensive, and only after the detectorist gets used to them, it will make sense to cover more complicated methods.
First things first, the order of switching the metal detector on for basic operations is to switch it on, and select Search Mode before you adjust Discrimination or Sensitivity. Search Mode actually provides enough tuning to start searching immediately, but Sensitivity and Discrimination may indeed require some additional tuning depending on the amount of trash on the location, and type of desired targets. Beginners should use Auto Ground Balance, but for highly mineralized grounds or unusual conditions of operation, Manual setting may be required.
To tune the Discrimination feature adequately, the user shoudl pay attention to the Notch Discrimination and Elimitation functions. You can switch on or off any combination of the pixels, depending on what targets you want to reject.
Now, as for highly trashy areas or areas with high concentration of iron or ferrous items, it is highly recommended to switch the Iron Audio feature off. If you already know there’s lots of iron there, additional Iron Audio will give you too many signals all over the place. Let the Discrimination do its job, and only switch Iron Audio on to double-check specific targets.
Garrett AT Pro Problems
Every metal detector has its problems, and Garrett AT Pro is not an exception. While it is a high quality machine which has been in steady demand since the time it was released, one of the most obvious problems with AT Pro is that the technologies used for it are a bit outdated by now. While AT Pro has all that it takes to bring valuable finds on various grounds, it has just rendered itself obsolete by the time of writing the review.
The other obvious problem which arises from the previous one is that Garrett AT Pro software cannot be updated online to fix bugs or upgrade the software at least a bit. In 2010 when the machine was first released, online software updates were not the case yet. However, today this is a huge disadvantage.
Another point to pay attention to is the fact that AT Pro cannot be used with wireless Z-Lynk headphones by Garrett.
And eventually, there is one clear structural problem that many metal detectorists from all over the world report. Because of some peculiarities of the shaft design, many AT Pro machines eventually see their control boxes coming off the shafts. This is a very unpleasant breakage which is not easy to fix, especially on the field. Different people manage it in different ways, but be aware that since the model is very old, Garrett is unlikely to fix this problem in the future, considering that it has not bothered fixing it during all these years. So, if you own Garrett AT Pro, just know that this breakage might happen, and be prepared.
Tips & Tricks for Garrett AT Pro Users
If you own a Garrett AT Pro metal detector and would like to learn some Garrett AT Pro tips and tricks, you will actually know most of them after reading this review, since it covers most of the nuances on settings and features. However, there are two more tips that may come handy at some point.
Saltwater Use
While AT Pro is fit for saltwater operation, overall any VLF continous wave metal detector faces additional challenges in highly mineralized conductive salt waters. The most important feature to utilize for efficient saltwater search is Ground Balance. For saltwater beach metal detecting, consider Ground Balance between zero and 20. You may want to reduce Sensitivity to stabilize the signal under saltwater conditions.
Intermittent Signals
If you believe all your settings are tuned properly and are relevant to the environment, then facing intermittent signals may mean that you have stumbled across a deeply buried target. Another version is a target placed at an unusual angle so the metal detector has hard time processing its response. To make head or tail of the signal, try scanning the patch that gives this signal from different directions. If you suspect more than one target giving the response, use Zero search mode, or use Pinpoint mode to locate every target separately.
