85mm GPS Speedometer Odometer | TFT Screen Marine Gauge with Voltmeter

This 85mm GPS speedometer combines speed, distance, heading, and battery voltage monitoring in one clear TFT display. It is built for marine and automotive use, giving you reliable data without complex wiring.

This gauge uses GPS signals to show Speed Over Ground from 0 to 600 km/h. The odometer tracks up to 999,999 km and can be reset using the back button. The trip meter returns to zero when power is disconnected, making it easy to track each journey separately.

The Course Over Ground feature acts as an orientation pointer, helping you stay on course. A built-in voltmeter monitors battery voltage from 9 to 32 VDC, so you can keep an eye on your electrical system. The TFT screen provides clear visibility in different lighting conditions.

With an IP67 rating, this speedometer is protected against dust and water. It is suitable for installation on the front of a motor yacht, boat, car, or outboard engine. The stainless steel and glass construction adds durability for harsh environments.

Key Features and Benefits

- GPS-based speed measurement that shows Speed Over Ground from 0 to 600 km/h for accurate real-time data

• Adjustable odometer with a 0 to 999,999 km range that can be reset using the back button for flexible trip tracking

• Course Over Ground orientation pointer that helps you maintain your heading during navigation

• Built-in voltmeter that monitors battery voltage from 9 to 32 VDC to alert you to electrical issues

• Three switchable speed units including knot, mph, and km/h for compatibility with different standards

• IP67 waterproof protection that allows the gauge to withstand dust and water exposure on deck or in a vehicle

Who Is This For

- Boat owners who want a reliable GPS speedometer with odometer and heading functions for navigation

• Yacht operators who need a dashboard gauge that monitors battery voltage alongside speed data

• Car and off-road vehicle enthusiasts who prefer a GPS-based speed display over traditional mechanical gauges

• Outboard engine users who require a waterproof gauge that can handle marine conditions

Usage Scenario

Mark runs a small fishing charter boat. His old mechanical speedometer stopped working after a season of salt spray. He installed this GPS speedometer on the console and connected the antenna. Now he sees his speed in knots, his trip distance, and his battery voltage all on one screen. The waterproof housing gives him confidence that the gauge will last through rough weather and frequent deck washing.

Micro Comparison

Traditional pitot-style speedometers rely on water pressure and can clog or give inaccurate readings at low speeds. This GPS-based gauge uses satellite signals to provide consistent speed data regardless of water conditions. The TFT screen offers better visibility than standard LCD displays, and the added voltmeter and heading functions reduce the need for separate instruments on your dashboard.

Questions and Answers

Question: Does this speedometer work without an internet connection?

Answer: Yes, it uses GPS satellite signals, not cellular data or Wi-Fi, so it works anywhere with a clear view of the sky.

Question: Can I switch between mph and km/h while driving?

Answer: Yes, you can switch between knot, mph, and km/h using the gauge controls.

Question: How do I reset the trip distance?

Answer: The trip meter returns to zero automatically when power is disconnected. You can also adjust the odometer using the back button.

Question: Is this gauge compatible with a 12-volt car system?

Answer: Yes, it operates on a 9 to 32 VDC input, so it works with standard 12V car and marine electrical systems.

Question: Does the antenna need to be mounted outside?

Answer: The antenna should be placed where it has a clear view of the sky to receive GPS signals. It comes with a 3-meter cable for flexible mounting.

Question: Can I use this on a motorcycle?

Answer: Yes, it can be installed on any vehicle where you want GPS-based speed and distance tracking, as long as it has a suitable power source and mounting location.
