Your boat isn’t just a vehicle: it’s an investment, a lifestyle, and your escape to the water. The Mariner Edition was purpose-built for safeguarding that investment every mile between the dock and the open water. Protecting not just your trailer, but the vessel riding on it.

Conventional TPMS systems were designed for passenger vehicles. The Mariner Edition was engineered for you: boaters, anglers, and watercraft owners who refuse to risk hidden trailer failures that could sink an entire weekend. Or worse, destroy their boat before it ever touches the water. With advanced monitoring of both axles and tires, it gives you the early warnings that mean the difference between a smooth launch and a nightmare on the roadside.

Why it Matters

  • Protect Your Vessel First: A blown tire or failed hub doesn’t just damage your trailer. It risks thousands of dollars in boats or watercraft strapped on top of it.
  • Prevent Catastrophic Failures: Real-time axle and hub temperature monitoring detects bearing stress or dragging brakes before they seize.
  • Keep Tires Road-Ready: Catch slow leaks and overheating before they spiral into a blowout that could leave you stranded far from the dock.

Built for the Marine Lifestyle: 100% waterproof, corrosion-resistant sensors built to thrive around ramps, splash zones, and salt air.

App Features
  • Bluetooth-enabled: works seamlessly in the background or foreground - play music or use navigation (keeps your phone accessible).
  • Dually trailer support: built for single or dual axle setups.
  • Smart problem detection: clear, easy-to-read alerts.
  • Trend identification: spot issues before they become problems.
  • Device agnostic: works on any device.
