When it comes to protecting your vehicle, most people think a GPS tracker is the ultimate solution. They provide real-time location data, route tracking and alerts — giving you peace of mind that your vehicle’s location is always known.
But there’s one thing most GPS owners don’t realise…
A $20 GPS Jammer can render a $300 tracker completely useless.
What is a GPS Jammer?
A GPS jammer (or GPS blocker) is a small electronic device that transmits radio signals on the same frequencies used by GPS satellites. When active, it overpowers the signal your GPS tracker relies on, preventing it from receiving accurate location data.
These devices are illegal to use or possess in Australia (and most countries), but that doesn’t stop them from being sold online for as little as $20. Unfortunately, car thieves know exactly how to use them.
GPS trackers are great — but not invincible
There’s no denying that GPS trackers are powerful tools. They provide detailed fleet data such as routes, speed, driver behaviour, and maintenance alerts — perfect for fleet management and business use.
However, when it comes to real-world theft recovery, they have weaknesses.
GPS trackers depend on three things:
- Satellite reception
- Mobile data (SIM connection)
- Power
If any of those are lost — or if a jammer is activated nearby — the tracker can’t transmit a location. That means even an expensive GPS tracker can go silent the moment a thief knows what they’re doing.
Where MagTag® is different
MagTag® doesn’t rely on GPS or SIM cards. It works through Apple’s Find My network, using secure Bluetooth signals picked up by millions of nearby iPhones worldwide.
So even if a GPS jammer is active or your vehicle is stored underground, MagTag can still update its location whenever it comes near another Apple device.
- ✅ Unaffected by GPS jammers
- ✅ No subscriptions or SIM cards
- ✅ One-year replaceable battery
- ✅ Works with iPhone
- ✅ One-off cost — no ongoing fees
The cost comparison that just makes sense
- Typical GPS tracker: $200-300 hardware + $10–$30 per month in data fees
- MagTag®: $29.95 once, no fees ever
For the price of one GPS tracker, you could hide ten MagTags across your vehicles, trailers, and valuables.
The reality
GPS jammers are cheap, illegal, and effective — and they’re already in the hands of professional thieves. That’s why relying on a single GPS tracker isn’t enough anymore.
Adding a MagTag® gives you a jam-proof backup that works when GPS doesn’t. Think of it as your silent insurance policy that never expires.
The takeaway
It’s not about replacing your GPS tracker — it’s about reinforcing it. GPS trackers are excellent for fleet data. MagTag® is the smarter backup for real-world asset recovery.
Because when a $20 jammer can block a $300 tracker, a $30 MagTag just makes sense.
