Garrett AT Pro Guide

Metal detecting in black sand can be difficult. Thanks to the heavy mineral concentration, you can pick up many false positives which will have you digging up empty sand pits. That is only if you’re using a basic metal detector to search though. You can get a more sophisticated model which is designed specially for the beach, and to breakthrough the tough detecting conditions. Enter the Garrett AT Pro. With it’s wide range of iron discrimination, you can filter through black sand to find real quality metal finds.

The secret to moving between different types of sand, which is common on beaches, especially California, is the ground balance setting. This, and the many other options are easy to switch and change with the intuitive interface. Although quite small in size, the LCD screen is packed with all the display settings you need, and allows you to monitor everything you need to have a successful search.

The Garrett AT Pro works with Very Low Frequency (VLF) detection technology. This means that there are 2 coils, and the outer coil is the one that transmits the signal, and then if that signal meets an object, and then bounces back up, there is the receiver, which is the inner coil, to receive the signal, and confirm to you that there is a positive find. This is the magnetic field. Although the Garrett AT Pro can also be used in other settings just as successfully, it’s featured here to give you the best roundup if your chosen ground is going to be mostly beach. The reason it is called AT is that it’s short for all terrain.

Garrett AT Pro Settings

You fire up your AT Pro with the mode button, and once it’s on, you can see all the different options you have before you start. With the mode button you can quickly change from coins preset, to your own custom preset, as whatever discrimination settings you apply, will be saved once you come back here. There is also a zero mode, which will detect almost everything. The notch discrimination is located on the right, and shows up under the top bar. You can discriminate silver, or gold, and even ring pulls, as well as a range of coins. There can be some overlap with gold and silver, so these are shown on the attached plastic menu too.

The sensitivity feature is great. Although in cheaper metal detectors, you might need to turn this down when you’re scanning beaches and sand, with the AT Pro, you can have that high almost anywhere. It’s that good at detecting real finds. The depth range is in 2″ increments, and can find up to, and greater than 10″. Perfect for most people.

You have on the left hand side of the controller the iron discrimination button. This allows you to discriminate against smaller metal objects, such as iron nails, and the best recommended settings is to put this between 35 and 40, but after using the machine yourself, you’ll learn what works where, and what are the best settings you need for that terrain. You won’t find many nails at the beach, but ring pulls and can’s can be frustrating finds, so even if you take a couple of test objects with you, like an old can and a gold ring. You can take some time to play around with them before starting your real search. This way you’ll already have your settings finely tuned from the start.

How to use the Garrett AT Pro

The first thing you will want to do is set the mode to standard, instead of pro. Pro features different audible sounds for different depths, but if you’re just starting out, you won’t need this just yet. You then have to ground balance the metal detector. This allows you to have the best accurate depths as possible. Just press the ground balance button, and start to lift the coil up and down a few times from the ground. Just make sure you lift it about 3-5″ max, and also ensure that there isn’t anything below the coil. This will throw it off. That should set the ground balance to something that you can easily work with.

As you start to scan the ground, make sure you keep the coil head horizontal to the ground, and just move it gently from side to side. Keep it within a comfortable left to right distance, as you might be scanning for a couple of hours, so you want to make sure your arm doesn’t tire easily from stretching. Make sure that you do overlap each are as you move forward.

If you test the AT Pro first, you’ll find that although sometimes bottlecaps do show up as roughly the same as coins, they also have a grunting audible sound. This is different from a coin which has a clean sound. So there is a little tip for you, but again, it’s worth setting up your own test board in your back garden, and playing around with the Garrett metal detector first.

Garrett AT Pro Dry Sand Settings

First, set the Garrett to pro mode, and then ground balance it as normal. Set your iron discrimination between 30-35. Although you will come across foils and ring pulls, you will be able to tell that is is them with the audible mode set to pro.

Garrett AT Pro Wet Sand Settings

Same again, set the mode to pro, and ground balance before you start. It’s important you do this as you move on or too each different type of sand. Then, set the iron discrimination to between 0 and 30.

If you’re going to be spending a lot of time combing the beach, then it makes sense to purchase on of these coil protectors. It will mean that your main coils are protected from any rough sand, and also small rocks that can accidently chip your main coils.

Garrett submersible headphones

For metal detecting at the beach with a set of headphones, your best choice with the AT Pro is this submersible ones. As well as being waterproof, they are dust, and sandproof. This means that they will last you a long time, instead of just using normal headphones, this makes more sense if you want to specialize with on the beach searching.
