52mm Digital GPS Speedometer TFT Screen | Odometer Gauge for Boat Car Yacht

This 52mm digital GPS speedometer gives you accurate speed and distance readings for your boat, car, or yacht. It displays speed in knots, MPH, or km/h and includes a built-in odometer and trip meter. The GPS antenna mounts outdoors for reliable satellite reception.

This gauge runs on 9 to 32 VDC power, making it compatible with both 12V and 24V electrical systems. The TFT screen shows your current speed, total mileage, trip distance, and a digital compass. You can switch between speed units easily using the yellow wire.

The speedometer saves your accumulated mileage even after a power loss. The trip meter resets to zero when power is cut, which is useful for tracking individual journeys. The unit is designed for front placement on your vehicle and comes with a GPS antenna and installation bracket.

Choose the standard package for just the gauge and antenna, or add the optional bracket for a secure dashboard mount. This speedometer is built for marine and automotive use but is not suitable for motorcycles.

Key Features and Benefits

- GPS-based speed measurement that gives you accurate readings without mechanical sensors

• Switchable units (knot, MPH, km/h) that let you match local or personal preferences

• Built-in odometer and trip meter that help you track total and per-trip mileage

• Digital compass display that shows heading from 0 to 359 degrees

• Wide voltage range (9-32 VDC) that works with both 12V and 24V systems

• Power-off data retention for accumulated mileage that keeps your records safe

Who Is This For

- Boat owners who want a reliable GPS speed display without mechanical connections

• Car or van owners who need a secondary speedometer with odometer functions

• Yacht or marine enthusiasts looking for a compact digital gauge for navigation

• DIY installers who want a simple plug-and-play speed solution with optional bracket

Usage Scenario

Mark owns a small fishing boat and was tired of his old mechanical speedometer giving inconsistent readings. He installed this 52mm GPS speedometer on his dashboard, mounted the antenna on the cabin roof, and connected the power to his 12V system. Now he sees his exact speed in knots, his total trip distance, and his compass heading all on one screen. The odometer keeps his accumulated mileage even when he turns the boat off, so he never loses track of his total distance traveled.

Micro Comparison

Traditional mechanical speedometers rely on pitot tubes or wheel sensors that can clog or wear out. This GPS-based gauge uses satellite signals to measure speed and distance, so there are no moving parts to maintain. It also offers three speed units and a digital compass, giving you more data than a standard analog gauge.

Questions and Answers

Question: Can I use this speedometer on a motorcycle?

Answer: No, this GPS speedometer is not suitable for motorcycles. It is designed for boats, cars, and yachts.

Question: Does the odometer save data when power is disconnected?

Answer: Yes, the accumulated mileage (ODO) is saved even after power loss. The trip meter (TRIP) resets to zero when power is cut.

Question: How do I switch between speed units?

Answer: Connect the yellow wire to the negative terminal (ground) briefly. Each contact switches the unit between knot, MPH, and km/h. The setting is saved automatically.

Question: What voltage does this gauge work with?

Answer: It operates on 9 to 32 VDC, so it works with both 12V and 24V electrical systems found in most boats, cars, and yachts.

Question: Does the GPS antenna need to be outside?

Answer: Yes, the GPS antenna must be installed outdoors for proper satellite reception. It is not suitable for indoor use.

Question: What is included in the package?

Answer: The package includes one 52mm speedometer and one GPS antenna. An optional installation bracket is available if you select that package.
