Why MiniMag™?

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 steel reinforced and will not break off. Our lock-tight latch 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.

    Did You Know They Come In 3 Sizes?
