85mm GPS Speedometer Odometer | TFT Screen for Boat Car Yacht

This 85mm GPS speedometer gives you accurate speed, distance, and direction data on a clear TFT screen. It is built for marine and automotive use, offering reliable performance in a compact dashboard-friendly size.

Tracking your vessel or vehicle speed is essential for safe navigation. This gauge uses GPS signals to measure Speed Over Ground (SOG) up to 600 km/h. The odometer tracks total distance up to 999,999 km, and the trip meter resets automatically when power is off. You also get Course Over Ground (COG) for directional awareness and a built-in voltmeter to monitor your battery between 9 and 32 VDC.

The TFT screen provides a bright, easy-to-read display in various lighting conditions. The unit is IP67 waterproof, so it handles splashes and rain without issue. You can switch between knots, mph, and km/h with a simple button press. The stainless steel and glass construction adds durability for long-term use on a motor yacht, boat, car, or outboard engine.

Installation is straightforward with the included GPS antenna and multi-plug socket. The back button lets you adjust the odometer reading when needed. This gauge gives you the essential trip data you need without complicating your dashboard.

Who Is This For

- Boat owners who want a reliable GPS speedometer for navigation and trip tracking

• DIY enthusiasts upgrading their dashboard with a modern TFT display and GPS integration

Usage Scenario

Mark takes his motor yacht out every weekend for coastal fishing. His old analog speedometer gave inconsistent readings, especially in choppy water. After installing this GPS speedometer, he gets steady speed data and accurate trip distance. The TFT screen is easy to read even with the sun reflecting off the water. He also checks the voltmeter display to confirm his battery is charging properly during the run. Now Mark feels more confident navigating narrow channels and planning fuel stops based on reliable trip data.

Micro Comparison

Traditional pitot-style speedometers rely on water pressure and can clog or give false readings at low speeds. This GPS-based gauge uses satellite signals, so it works accurately regardless of water conditions. The TFT screen also provides a clearer, more modern display than standard LCD or analog dials.
