You have the best GPS tracker and you attach it to your car. After an hour of driving, you find out that your most beloved tracker got detached.

What’s worse is that, when you were able to retrieve it, it is all dirty and cracked. It might seem like a nightmare, but this can turn into reality if you do not invest in a good GPS tracker case.

It is a protocol that you get yourself a GPS tracker case if you plan on taking out your tracker or putting it under your car. The reasoning behind this is simple; you need to keep it safe. However, there are now a lot of cases to choose from, and you might get overwhelmed.

In this article, we are going to review the Spy Tec M2 Magnetic Case. It claims to be one of the strongest and one of the most durable cases for GPS trackers.

Another feature that it boasts is that it is waterproof. We are going to put these claims to the test, and list down the advantages and disadvantages of using such a case.

This case just might be the one you are looking for. Read on to find out.


A quick look at this case and you will surely know that it means business. Its exterior is quite bulky, but with its looks alone, you can confirm that it is sturdy.

  • It has a sturdy design making it ideal for long-term use.
  • It is also waterproof and dust-proof.
  • The casing is mostly compatible with GL-200 and GL-300.
  • It can fit other models, as long as it slides in with much ease.
  • The magnetic part stems from the two magnets at its back, where you can attach it to any metal and flat surface.
  • The seal design is made to prevent any corrosion or moisture for your GPS tracker.
  • The case is sturdy enough to be put outside a moving vehicle, or even be submerged in water.
  • The material used is plastic that is high-grade and industrial-strength, that it will not hinder any incoming and outgoing signals.
  • It also has an easy removal feature, wherein the surface that you attached the case or mount, remains the same and unaltered.


  • The battery life lasts for a long time, approximately two to three weeks, even with continued use.
  • The magnets are extremely strong that you might mistake the mount as being superglued to the surface.
  • It is made of sturdy material that it can withstand the shock of dropping the mount and other elements that might hit it when putting outside the car.
  • It is really waterproof. Once you seal the opening, no amount of water pressure can get into the case.
  • There is also a bit of support given to your tracker as it has a soft cushion inside.
  • It is easy to set up and easy to use.
  • It can last outside in the snow.


  • If the tracker that you put inside the case does not fit properly, you might encounter signal issues.
  • You have to always attach it to a flat metal space, or else the magnets will not stick properly.
  • The screws that come with the case are problematic. They tend to loosen that it risks holding the case in place. Definitely, you have to buy different screws to make it work.
  • Its size is very awkward, it is too big for small GPS trackers, and it is too small for bulky trackers. So this is an issue when it comes to fitting in a different model of GPS tracker.

Summary of the Features

The Spy Tec M2 Magnetic Case is a weatherproof and waterproof GPS tracker case. The case is very sturdy and durable that you can place it outside your car.

Moreover, it can withstand high water pressure and even snow. Surely, this is the case to get in order for you to protect your GPS tracker, most especially when you are hiking.

It is mostly compatible with GL-200 and GL-300 GPS trackers, but it can also be used for other trackers, just as long as they fit properly inside the case. Additionally, it is made up of high-grade plastic that is industrial-strength at the same time, so as not to interfere with any incoming and outgoing signals.

Comparison with the Monster Magnetics Waterproof Magnetic Stash Box

At a glance, the Monster Magnetics Waterproof Magnetic Stash Box looks stronger than the Spy Tec M2 Magnetic Case, and it probably is, as the former cannot only keep your GPS tracker, but it can also hold cards, car keys, and other gadgets.

That strength is also its weakness. It is considered a weakness for the fact that it caters to a lot of objects, that it does not really specialize in storing a GPS tracker. When it comes to devices such as that, you need to have something that is solely made for that purpose.

Another thing to note is that the box can also store car keys, the metal from the key can put off the signals of the GPS tracker, that might lead to false readings and ultimately, damaging the receiver.

Both of these cases are sturdy and durable; however, the Spy Tec M2 Magnetic Case is slightly better as it was made specifically to house a GPS tracker. Therefore, it has features that are catered to support your tracker.


We highly recommend that you check out the Spy Tec M2 Magnetic Case,  if you have the GL-200 and GL-300 GPS trackers. If you do, then this case is perfect for you. Even though the brand says that this case can accommodate other trackers, experience dictates otherwise.

If you are someone who takes GPS tracking seriously, and you need a case to properly support it, this case is a sturdy and durable one. However, it does have its disadvantages as with its screws being screw-ups. No pun intended. But this problem can be easily averted with just a quick trip to the hardware.

Additionally, this case can withstand different weather and temperatures that you are ensured that your tracker inside will be safe. At the same time, it is waterproof. These features and more are things that you might think are impossible to achieve, but in this case, it will become a reality.
