GPS Speedometer and Tachometer Combo | 2 in 1 110mm Gauge with GPS Antenna

This 2 in 1 gauge combines a GPS speedometer and tachometer in a single 110mm unit. It provides accurate speed readings up to 200 KMH and RPM monitoring up to 8000 RPM, making it a practical upgrade for cars, boats, and marine applications. The red backlight and turn signal indicators keep your dashboard clear and functional.

Install this gauge to replace your old speedometer or add a modern digital display to your vehicle. It works with universal gasoline and diesel engines on 12V or 24V systems. The included GPS antenna connects quickly for reliable satellite speed tracking without needing a mechanical sensor.

The tachometer monitors engine RPM to help you shift at the right time and avoid over-revving. With a built-in overspeed alarm and customizable speed ratio, you can adjust the gauge to match your vehicle's specific setup. The red backlight ensures visibility during night driving or low-light conditions.

This gauge is built with a durable plastic housing and a 110mm diameter face. It includes wiring for left and right turn signals, high beam indication, and a buzzer alarm. The simple button interface on the back lets you adjust settings for speed ratio, alarm thresholds, and trip reset.

Key Features and Benefits

- GPS speed measurement that provides accurate KMH or MPH readings without wheel sensors

• Tachometer up to 8000 RPM that helps monitor engine performance and prevent over-revving

• Red backlight that improves readability during nighttime or low-light driving conditions

• Turn signal and high beam indicators that keep essential driving information on one gauge

• Overspeed alarm that alerts you when you exceed a set speed limit for safer driving

• Universal 12V/24V compatibility that works with gasoline and diesel engines in cars and boats

Who Is This For

- Car owners who want a combined speedometer and tachometer for a cleaner dashboard layout

• Boat owners who need a GPS-based speed gauge that works on water without mechanical sensors

• DIY mechanics and custom vehicle builders looking for a functional gauge for projects or restorations

• Drivers who want an overspeed alarm and adjustable speed ratio for better control and safety

Usage Scenario

Mark was restoring an older pickup truck and wanted a modern dashboard without cutting new holes. He found the old speedometer was inaccurate and the tachometer was missing entirely. After installing this 2 in 1 gauge and connecting the GPS antenna, he had both speed and RPM readings on one clean display. The red backlight made it easy to see at night, and the overspeed alarm helped him stay within safe limits during highway driving. The gauge fit perfectly into the existing 110mm opening.

Micro Comparison

Unlike separate speedometer and tachometer units that take up more dashboard space, this 2 in 1 gauge combines both functions in a single 110mm housing. The GPS speed reading eliminates the need for mechanical speed sensors, which can fail or require calibration. The built-in turn signal and high beam indicators also reduce the number of separate lights needed on your dash.
