85mm 6 in 1 GPS Speedometer and Tachometer | Digital Gauge with Oil Pressure, Water Temp, Fuel Level, and Voltmeter

This 85mm digital gauge combines six essential instruments into one compact display. It gives you GPS-based speed, tachometer readings, oil pressure, water temperature, fuel level, and battery voltage all in one unit. Designed for cars, boats, and motorcycles, it helps you monitor your engine and vehicle performance at a glance.

The gauge uses a GPS antenna to measure speed over ground, so it works without needing a mechanical cable. It also tracks your odometer, trip distance, and course over ground. The display is easy to read, and the stainless steel bezel and anti-fog glass make it durable for outdoor use.

You can connect this gauge to your existing sensors or buy them separately. It supports a 240-33 ohm fuel float sensor, a 1/8 NPT oil pressure sensor, and a water temperature sensor. The voltmeter works with 9-32V systems, making it suitable for most 12V and 24V vehicles.

This gauge is built to handle tough conditions. It is waterproof with an IP67 rating, so it can resist water and dust. The 85mm size fits standard gauge pods and dash openings. Whether you are upgrading your dashboard or building a new one, this gauge gives you all the data you need in one place.

Key Features and Benefits

- GPS speed measurement that gives you accurate speed over ground without mechanical cables

• Six functions in one gauge that saves dashboard space and reduces wiring complexity

• Stainless steel 316L bezel and anti-fog glass that resist corrosion and keep the display clear

• IP67 waterproof rating that protects the gauge from water and dust in marine and off-road use

• Wide voltage range from 9 to 32V that works with most 12V and 24V electrical systems

• Adjustable fuel level signal that lets you match 0-190 ohm or 240-33 ohm sensors

Who Is This For

- Boat owners who want a single gauge for speed, engine, and fuel monitoring

• Car and truck enthusiasts upgrading their dashboard with a modern digital display

• Motorcycle riders who need a compact and waterproof gauge for speed and engine data

• DIY builders and mechanics installing a new instrument cluster in a custom vehicle

Usage Scenario

Mark owns a small fishing boat and was tired of looking at three separate gauges for speed, temperature, and fuel. He installed this 6 in 1 gauge on his dash and connected it to his existing sensors. Now he sees his GPS speed, water temp, fuel level, and engine hours all on one display. The waterproof housing gives him peace of mind when the spray hits the dash. He no longer has to guess his fuel level or worry about overheating.

Micro Comparison

Unlike single-function gauges that require multiple holes and separate wiring, this unit combines six readings into one 85mm display. It uses GPS for speed, so you do not need a mechanical speedometer cable. The IP67 waterproof rating makes it more durable than many standard automotive gauges that are not sealed against moisture.
