6 In 1 85mm GPS Speedometer with Tachometer and Fuel Level Gauge for Car Boat Marine 12V 24V | Multifunction Gauge

MyPetiteCar.com

This 6-in-1 gauge combines a GPS speedometer, tachometer, fuel level gauge, oil pressure gauge, water temperature gauge, and voltmeter into one compact 85mm unit. It is designed for 12V and 24V systems in cars, boats, and marine applications.

You get all the essential engine and vehicle data on a single, easy-to-read display. The GPS speedometer provides accurate speed readings in km/h, mph, or knots. The tachometer tracks RPM up to 9999, and the fuel level gauge works with standard 0-190 ohm or 240-33 ohm sensors.

Built with a waterproof plastic housing, this gauge is ready for demanding environments. It includes an oil pressure sensor, water temperature sensor, fuel level sensor, and a tachometer sensor, giving you a complete monitoring solution right out of the box.

Setup is straightforward with the included manual. The gauge offers adjustable speed ratio, unit switching, and customizable engine hours and odometer settings. It is a practical upgrade for anyone who needs reliable data without multiple separate gauges.

Key Features and Benefits

- 6 functions in one gauge that saves dashboard space and simplifies wiring

  • GPS speedometer with 0-600 km/h range that provides accurate speed data without mechanical connections
  • Tachometer up to 9999 RPM that helps you monitor engine performance
  • Waterproof plastic housing that withstands moisture and splashes in marine and outdoor use
  • Adjustable speed ratio from 1.0 to 360.0 that lets you calibrate for different vehicles and tire sizes
  • Compatible with 9-32V DC systems that works on both 12V and 24V electrical setups

Who Is This For

- Boat owners who want a single gauge for engine vitals like speed, temperature, and oil pressure

  • DIY car builders upgrading their dashboard with a modern multifunction display
  • Marine enthusiasts who need a waterproof gauge for saltwater or freshwater environments
  • Off-road vehicle owners looking for GPS speed and engine data in one compact unit

Usage Scenario

Mark runs a small fishing boat on a lake. He used to have three separate gauges for speed, temperature, and fuel level, but they took up too much space and were hard to read at a glance. After installing this 6-in-1 gauge, he now sees everything on one screen. The GPS speedometer works without a pitot tube, and the waterproof design handles spray from the water. He can quickly check his RPM, water temp, and fuel level without looking away from the water for too long.

Micro Comparison

Instead of buying four or five separate gauges that each need their own wiring and mounting hole, this single 85mm unit gives you all the data in one place. It includes the sensors you need, so there is no hunting for compatible parts. The GPS speedometer is more reliable than mechanical speedometers that can jam or wear out over time.
