1. Garrett 1140900 Pro-Pointer AT Waterproof Pinpointing Metal Detector Review

Garrett 1140900 Pro-Pointer AT Waterproof

This little pocket detector is perfect for taking around the place with you, and whipping out whenever you think you may have hit upon a treasure trove (or when you are looking for those screws you lost last week!)


  • Fully waterproof up to 10 feet. You can drop this detector in a puddle and it won’t get damaged – in fact it will be fine falling into a pond of up to 10 feet deep.
  • Brightly colored, so easy to find.If you drop this somewhere in a field, you won’t have to worry about losing it forever – it is a bright orange color so you will be able to spot it from miles off.
  • Easy to retune. One simple button will remove the interference of the surrounding environment, so you can narrow down your detection field and precisely pinpoint larger areas.
  • Highly sensitive for the pinpointing of small targets. This detector won’t just pick up large items; it is a sensitive gadget and so will pick up signals from even small objects, meaning that you can use it to pick up the smallest of interesting fragments.


  • Not salt water proof. Although this model is waterproof, it is not resistant to seawater, so if you drop it in the ocean it may stop working, due to the salt water corroding the parts. I guess that’s not an issue for most farm owners anyway.


An incredibly handy metal detector, that you can carry around with you wherever you go, to discover buried treasure, lost coins, or just that pair of pliers that you lost in the mud a month ago.


2. Minelab 3720-0002 Equinox 800 Metal Detector Review

Minelab 3720-0002 Equinox 800

This is a serious metal detector, for the dedicated hobbyist or someone who is convinced there is a Roman fort under their farm – or just someone who loses a lot of metal items under the mud!


  • Incredibly light and easy to carry around. Weighing in at under 3lbs, this detector won’t strain your arms as you carry it around searching for lost treasure.
  • Waterproof to large depths. This model is fully submersible, making it ideal for use around waterways around your farm. It won’t work as an undersea detector, but you don’t have to worry about it getting a bit soggy.
  • It comes with accessories. With this detector you will receive wireless headphones, a wireless audio module, a USB charging cable and a charging cable for your headphones.
  • Clear tones telling you where to dig. You won’t miss a trick with this detector, as it can direct you to where it is worth getting your shovel out, with no false signals making you waste your time.


  • There is no grip on the neck. A smooth hand hold is all very well, but it can strain your arm muscles if you keep holding on to it non stop for hours on end, with no other grip to give your fingers a break.


This is an incredibly sophisticated detector, that can help you pinpoint even tiny nuggets of metal beneath the earth’s surface and help you find even deeply buried items without wasting any time making you think something is there when it isn’t.

Frequently Asked Questions

best metal detector for farm fields Frequently Asked Questions

What Makes a Good Metal Detector?

When choosing the right metal detector for your farm, you want to make sure you’re not wasting your money. Choosing a good one is important, as well as choosing one that’s a good fit for your particular farming needs.

A good metal detector is highly sensitive, picking up on even the smallest pieces of metal like screws and nails. The ability to calibrate the detector for certain metals only is also useful.

You may also want to consider factors such as whether or not it’s waterproof, has an LCD display screen, and how large the coil is (larger coils generally are more sensitive at greater depths).

Why Is It Important to Have a Good Metal Detector for Your Farm?

Having a reliable metal detector on your farm is important for the health and safety of your livestock. Using a metal detector before moving livestock into an area for grazing can help you find any small or sharp objects that could cause injury or choking.

Additionally, your metal detector can help you locate large metal objects underground before digging, and they can also help you make a variety of interesting discoveries of things that may be buried underground.

Can Metal Detectors Work in Old Farm Fields?

Yes, metal detectors can work in old farm fields. Whether you just moved to an old, long-abandoned property or you’re simply looking for buried treasure on one, a metal detector may serve you well.

That said, a high-quality, highly sensitive metal detector will work better than a cheaper one. Old farm fields may be overgrown, and any objects worth finding may be buried under extra layers of ground and vegetation.

How Do You Use a Metal Detector on Your Farm?

Using a metal detector is easy. These devices are generally battery-powered, so all you have to do is make sure the battery is charged, turn it on, and sweep it across your field in a back-and-forth motion, taking care not to bump it against rocks or other hard surfaces.

For specific instructions, read your owner’s manual before using your metal detector for the first time. Different models may have different battery requirements, may require you to hold the head at different heights above the ground, etc.

How Do You Properly Maintain Your Metal Detector?

To maintain your metal detector and extend its life, clean it after every use to remove dirt and debris. Do not use harsh chemicals; a simple cloth or brush will do.

Store the detector away from extreme temperatures, direct sunlight, and humidity. Remove the batteries between uses if you don’t use the detector very often.

Check all of the electronic connections and waterproofing seals and gaskets regularly. Update any software and calibrate the device on a regular basis.


A metal detector is a great addition to any farm worker’s tool kit, next to the tools such as stick welders or chainsaws. They are great for finding lost metal equipment, as well as for finding buried treasure!

What have you go to lose? Maybe an entire haul of Roman coins – or even just that spanner set you lost in the mud a while back…
