Zircon MT6 VS Zircon MT7 – Which Stud Finder Is More Powerful?

If you’re looking for a stud finder or metal scanner, Zircon makes some of the best models available. The overall quality and value of their products are celebrated by DIYers and working professionals alike.

Zircon’s popular metal scanners, the MetalliScanner MT6 and MetalliScanner MT7 are metal detectors designed to scan through concrete and any non-metallic surface such as wood, marble, or tile so you can locate things such as:

  • Steel rebar
  • Copper plumbing
  • Cables
  • Pipes
  • Nails in reclaimed wood
  • Tacks
  • Electrical boxes
  • Conduit
  • Any other metal building materials

Scanning for metal will help you know where you can and can’t drill or cut into concrete. This will save you valuable time and money replacing damaged saw blades and drill bits, as well as not damaging important metal building structures.

In this article, we aim to compare the two models to see whether the MT6 or MT7 is superior and which one you should buy for your next job or project.

We’ll go over the features of each, how they are similar and different, and ultimately, which one is better.

Which One Is The Winner

In the interest of saving you some time, let’s go ahead and get the winner out of the way now. We encourage you to keep reading so you can learn some more details about each of these metal scanners.

After all, this is just our opinion. You may come up with your own after reading about the different features of the MT6 and MT7.

We believe the winner between these two Zircon MetalliScanner models is the MT7

We came to this conclusion because while both models serve the same function, have the same accuracy, and are altogether very similar, the MT7 has a few additional features that make it a better value.

For only a small increase in price, the MT7 includes a backlit display and a pivoting handle for less interference and greater reach.

These may seem like small things, but any little feature that can make a job more efficient is well worth it.

Zircon MT6

The Zircon MetalliScanner MT6 is the earlier model of the two and provides some basic features. The MT6 allows you to properly scan concrete for ferrous and nonferrous metals so you can be sure of where you can and can’t cut or drill.

The Zircon MT6 can locate metals up to 6 inches deep in concrete or any other nonmetallic surface.

A series of depth bars visible on the display will indicate the depth of the objects. The closer the unit is to the object, the more depth bars will appear.

When the scanner approaches a metal object, a plus sign (+) will appear as you get closer to the metal object, and a minus sign (-) will appear when the scanner is moving away from the embedded metal object.

A magnet icon indicates whether the scanned metal is ferrous or nonferrous. For ferrous metals, a magnet icon will be visible on the display. For nonferrous metals, the magnet icon will be crossed out indicating non-magnetic metals such as copper plumbing.

The LED screen of the Zircon MT6 can identify objects to the nearest inch. The Zircon MT6 can also be switched to metric measurements if desired.

The Zircon MT6 is a small, lightweight, and compact metal scanner that is perfectly capable of handling the task of locating embedded metal materials on a variety of surfaces.

What we like about the MT6

There are many positive attributes to the MT6. It’s a simple yet effective tool in a small size, which may be all you need for your next project.

The things we like most about the MT6 are:

  • Small, lightweight, and compact size
  • Long battery life

What we don’t like about the MT6

With the positives of the MT6 aside, no tool is perfect.

Some things we don’t like about the MT6 are:

  • Display is hard to read in low light
  • Limited reach because it must be handheld
  • The user’s hands can sometimes interfere with the scanning

These negative aspects don’t make the MT6 useless by any means, but you should definitely keep them in mind when deciding between the MT6 and MT7 models.

Zircon MT7

The Zircon MetaliScanner MT7 is a new and improved upon version of the MT6 with a few added features to make the job easier.

The MT7 can scan any nonmetallic surface such as wood, concrete, or tile for any embedded metal materials.

Utilizing the MT7 removes the need to hire costly scanning professionals or use more complicated and costly metal scanners.

The Zircon MT7 has two scanning modes. The standard mode will scan surfaces up to 3 inches deep, and deep scan mode for depths of up to 6 inches.

For the MT7, the same depth bars as the MT6 indicate the depth of the object, with more bars being shown the closer the unit is to the object. The MT7 unit can also be calibrated for metric or imperial measurements.

A plus sign (+) will appear as the unit gets closer to an embedded object, and a minus sign (-) will appear when the MT7 is moving away from the object.

To precisely locate the metal object under the surface, make two marks. Make one mark where the plus sign first appears, and another when the minus sign first appears after.

The same magnetic icon on the display will appear to indicate a ferrous or non-ferrous metal. This will help you determine what kind of metal is beneath the surface.

Additionally, a pivoting handle is an added feature for the Zircon MT7 that allows for less interference and for extended reach.

The Zircon MetalliScanner MT7 is the new and improved version of the MT6. With a backlit screen, pivoting handle, and a larger, more sturdy design, the MT7 is a true workhorse.

What we like about the MT7

There are plenty of things to like about the MT7. Many of the negative aspects of the MT6 have been taken into account and improved upon for this model.

The things we like about the MT7 are:

  • The pivoting handle allows for more reach and less interference from the user’s hands.
  • The LED-backlit display helps users see the screen in low-light situations.

These additional features that we like about the MT7 played a big part in deciding the MT7 as the winner.

However, the MT7 is not entirely perfect as we’ll explain soon

What we don’t like about the MT7

The MetalliScanner MT7 has a couple of negative attributes you will need to know about before deciding on which model to buy.

The things we don’t like about the MT7 scanner are:

  • Large, heavy, and bulky compared to the MT6
  • Shorter battery life when the LED Backlight is engaged

Even with these downsides, we truly believe the MT7 is the better choice between the two models.

On the other hand, these things may deter you away from the MT7 and towards the MT6 instead. This is fine, as everyone has their preferences. The best model won’t be the same for everyone.
