Why MiniMag 2™?

Tens of thousands of our magnetic stash boxes are in the field right now! Law enforcement and professional investigators mount GPS trackers under vehicles. Professional grade. 

The main problem we see in similar products is the quality of the enclosure itself. Magnets break off, moisture sealant is inadequate. Ours are countersunk right into the enclosure and will not break off. Our screw/rivet-free design and gasket completely seal your contents from the elements.

But broken magnets and leaking enclosures aren't the only problems. Worse yet is something that seems simple, but that you never thought about until now.

You plan to mount it underneath a vehicle. When you crawl under a vehicle to place it, where do you put it?

If you fail to mount a GPS tracker in a recommended location, you're rendering it useless. You're blocking GPS and cellular signals and it doesn't work. Worse yet, your placement could damage or destroy your expensive tracker. Or you lose it.

We got you covered. We teamed up with GPS tracking experts. Our enlightening (and illustrated) Under-Vehicle Placement Guide will show you what to do. Follow the instructions printed on the outside of the packaging to download it - for FREE.

Excellent Product! Sturdy and Reliable...

The 'Monster Magnetics MiniMag 2 Waterproof Magnetic Stash Box' is by far the best stash box I have own. This product is the 'Bomb'! Unbelievably strong and holds up to rigorous truck rides. I would recommend this product to anyone who is looking for a good stash box for their auto keys and fob or small items. I have one auto key, two smaller keys, and two lug nut keys that I carry in mine...

As advertised and works well

Only had to use a hand full of times wish it was twice as big but that’s not important I’d be willing to purchase another one if I need to.
