MOTOR METER RACING W Pro Series 110mm GPS Speedometer - Accurate

In this review of the MOTOR METER RACING W Pro Series 110mm GPS speedometer, the bottom line is simple: it is for drivers or boaters who want a compact, durable digital speed and mileage solution with clear illumination and reliable memory functions. The gauge is aimed at users replacing a worn instrument or installing an aftermarket cluster where a GPS-based readout and a crisp white LED display are priorities, and the single biggest reason to buy is the combination of a high quality stepper motor movement plus IP67 waterproof construction that suits road and marine use.

Key Features

• 110mm Size: The compact 110mm (4-3/8in) diameter fits common dash cutouts for straightforward replacement or new installs.
• GPS Speed Sensing: GPS operation provides speed readings without a mechanical cable and supports both 12V and 24V negative ground systems.
• Durable Construction: IP67 waterproof rating, 316 stainless steel bezel and ABS housing make the gauge rustproof and suitable for marine environments.
• Clear Visibility: Convex clear lens, black dial, red needle and white LED illumination deliver an easy-to-read display day or night.
• Odometer Memory: Odometer records to 99,999.9 miles and includes adjustable and power-off memory functions to preserve total mileage.
• Complete Package: Ships with the speedometer, GPS sensor, power harness, gauge visor and installation instructions to simplify setup.

Who It's For

This unit is best for automotive owners, truck drivers and recreational boat operators who need a compact GPS speedometer that resists water, fog and UV while offering precise stepper-motor movement for smoother needle action. It also suits DIY installers who appreciate a bundled sensor, harness and clear instructions so installation can be completed quickly.

Those who should look elsewhere include users who require speeds above 120 MPH, fleets needing advanced telematics, or buyers who prefer an OEM-matched instrument cluster with manufacturer-specific styling or CANbus integration.

Pros & Cons

Pros

• Well-built IP67 design and stainless bezel provide true waterproofing and corrosion resistance for marine or off-road use.
• White LED illumination and convex lens make the black faceplate and red needle very easy to read in varied lighting.
• GPS sensor eliminates mechanical cable routing and the odometer retains mileage with power-off memory.
• Package includes sensor, harness and visor so most users have what they need for installation.

Cons

• Some customers reported mixed durability experience, so a small number may encounter early failure under heavy use.
• Maximum readout is limited to 120 MPH, which is unsuitable for higher-speed specialty vehicles.
