A PLB is useless with a dead battery. The TTX3 utilizes a non-rechargeable, high-energy Lithium battery pack. Here are the cold, hard stats:
Pro Tip: Always check the "Replace by" date on the back of the unit annually.
The TTX3 Multi 41 is designed to fit a wide range of the Mercedes lineup, particularly those requiring a 66.6mm center bore. It is most popular on:
Note: Always verify clearance for your specific brake package. The TTX3 generally clears standard AMG brakes, but massive ceramic kits may require a test fit.
The Artex TTX3 Multi 41 is an excellent choice for: artax ttx3 multi 41
Consider alternative if: You require Galileo/GPS redundancy, return link service, or a 406 MHz test mode.
Final Verdict: Reliable, field-proven, and cost-effective for Part 91 operators. The GPS integration is a major safety upgrade over non-position ELTs.
The most confusing part of the name for many buyers is the "Multi 41" designation.
In wheel terminology, "Multi" usually refers to the bolt pattern. The Artax TTX3 Multi 41 is drilled with a 5x112 bolt pattern (the standard for Mercedes-Benz), but often features a "multi-drilled" or "multi-fitment" hub design. This allows the wheel to accommodate various stud configurations, though the TTX3 is most commonly sought after by Mercedes owners looking for that perfect factory-plus fit.

The "41" is the game-changer. This typically refers to the Offset (ET). An offset of ET41 is an aggressive yet street-able stance for many modern Mercedes models. It pushes the wheel outward toward the fender lip just enough to give the car a wider, more planted track width without the need for spacers.
If you roll your vehicle in the Australian Outback or the Utah desert, you might not be able to reach a satellite messenger (like a Garmin inReach) in the glove box. The TTX3 can be mounted via the optional Artex Reel Mount on your chest harness or roll cage, accessible even when upside down.
You can buy the Artex TTX3 Multi 41 at any aviation or marine supply store, but the hardware is useless without registration.
In the US, you must register your beacon's unique 15-digit Hex ID with NOAA (National Oceanic and Atmospheric Administration). In the UK, it is the MCA (Maritime and Coastguard Agency). This registration links the beacon to your emergency contact details, vehicle description, and medical needs. Pro Tip: Always check the "Replace by" date
Warning: Unregistered beacons cause false alarms. Rescue centers will still receive the signal, but they won't know if it is a real distress or a test. Response times are significantly delayed for unregistered beacons.
The "TTX3" designation refers to the wheel's design architecture. It features a classic twin-spoke layout (sometimes described as a 5-double-spoke design). This is a timeless aesthetic that works beautifully on almost every modern Mercedes chassis, from the A-Class hatchback to the S-Class sedan.
The design serves a functional purpose as well as an aesthetic one. The open-spoke architecture allows for generous brake cooling and provides a clear view of the calipers behind the wheel—perfect if you are running a big brake kit.
