Engineered to deliver real-time metrics with zero latency, utilizing advanced GPS tracking, Bluetooth integration, and multi-sensor kits.
The Evolution of Digital Instrumentation: Transitioning from Analog Transmissions to High-Refresh GPS Telemetry.
Tailored configurations across a dual-brand framework to meet precision motorsports requirements and broad automotive modification demands.
Developed in close collaboration with a leading Australian engineering firm, SincoTech represents the apex of high-performance racing telemetry. These multi-function dashboards, such as the DO926NB, DO908, and DO907, integrate up to 10 key parameters (RPM, Speed, Boost, EGT, Water/Oil Temp, Oil Pressure, and Voltage) onto high-brightness LCD and OLED screens. Features include high-luminance programmable shift lights and waterproof external sensor kits designed to withstand high G-forces and severe track conditions.
Designed for car enthusiasts and performance tuning garages, GragonGauge offers a comprehensive catalog of standalone and combined meters. We manufacture instruments in industry-standard dimensions: 52mm (2 inches), 60mm (2.36 inches), and 85mm (3.75 inches). These fitments support custom color backlighting, stepper motor needles, and custom-calibrated sensors to ensure clean dashboard integration for classical modifications and modern upgrades alike.
Advancing precision telemetry through next-generation signal filtering and integrated IoT features.
Traditional GPS speedometers refresh at a standard 1Hz rate (once per second), which can lead to noticeable lagging during rapid acceleration or heavy braking. Our engineering roadmap includes transitioning key product lines to 10Hz and 25Hz multi-constellation GNSS receivers. This increases data update rates to 10–25 times per second, providing instant speed feedback and eliminating digital needle lag on professional racing dashboards.
To maintain accurate speed readouts when passing under bridges, through tunnels, or inside dense urban canyons, our digital speedometers employ proprietary Kalman filtering software. By blending accelerometer inputs (inertial navigation) with satellite positioning, our systems prevent speed drops or erratic jumps, offering a smooth and consistent visual experience even when GPS signals are temporarily obstructed.
The next generation of SincoTech and GragonGauge digital dashboards will feature concurrent CAN-Bus reading capabilities. By combining GPS-derived speed data with engine metrics directly retrieved from the vehicle controller area network (CAN-Bus), our displays provide a comprehensive view of engine loads, fuel economy, gear positions, and diagnostic trouble codes (DTCs).
Optimized instrumentation layouts designed for fleet management, electric platforms, and marine operations.
For long-haul transport and commercial trucking, standard mechanical wear leads to high maintenance overheads. Our GPS-independent speedometers provide fleet operators with highly reliable speed tracking that is immune to gearbox alterations, wear-and-tear, or custom wheel profiles. This guarantees consistent log-book records and prevents speeding violations due to instrumentation inaccuracy.
EV powertrains lack the mechanical vacuum and oil lines common to internal combustion engines. Digital dashboards must parse high-voltage data streams. Our digital display gauges link with EV control units via customized transceivers, projecting real-time voltage, battery state of charge (SoC), thermal monitoring, and GPS-synchronized speed without placing load on the low-voltage auxiliary networks.
Marine vessels and off-road crawlers navigate terrains where wheel-speed sensing is unreliable due to water slippage or muddy tracks. GPS speedometers measure true ground speed directly from satellite tracking. Featuring IP67 dustproof and waterproof ratings, high-contrast anti-glare screen treatments, and corrosion-resistant alloy bezels, our systems perform reliably in marine environments and remote off-road tracks.

Inside Ruian DongOu: High-precision manufacturing systems, component tracking, and end-to-end quality assurance.
Headquartered in Ruian, Zhejiang—the manufacturing hub of China's automotive components industry—Ruian DongOu Automobile Meter Factory utilizes regional supply chain networks to source high-grade raw components, including Japanese stepper motors and Swiss-made digital pointer systems. Over our 38-year history, we have transitioned from manual assembly benches to automated production lines.
Our assembly floors feature dust-controlled surface mount technology (SMT) rooms, automatic optical inspection (AOI) testers, and high-frequency calibration systems. Every batch of GPS speedometers undergoes rigorous climate-chamber aging, thermal shock testing, and high-vibration exposure to verify that all electronic contacts and screen controllers can withstand extreme in-vehicle dashboard heat and heavy physical vibration.
All PCBs, microcontrollers, and capacitors are sourced from verified suppliers with full batch traceability to eliminate counterfeits and maintain long-term component durability.
Our digital calibration benches test speedometers across their full sweep, checking indicator response at 20, 60, 120, and 200 km/h to guarantee real-world precision.
Completed units undergo continuous powered operation inside thermal chambers at temperatures ranging from -40°C to +80°C to verify thermal stability before packaging.

Direct technical answers regarding performance, installation, and integration of digital GPS instrumentation.
Traditional speedometers count the output shaft rotations of the gearbox and calculate speed using assumptions about tire diameters and final drive ratios. Changing tires or sprockets alters the readout. A GPS speedometer processes high-frequency signals from satellite networks to calculate true ground velocity. This makes it independent of the vehicle's mechanical components, wheel spin, or tire size variations, ensuring consistent precision.
To prevent speed drops inside tunnels or under overpasses, our high-performance models (such as the SincoTech racing dashboards) feature intelligent Kalman filtering algorithms. When the GPS signal is temporarily lost, the software calculates speed based on your previous velocity and direction. For long-distance driving in areas without satellite coverage, we offer dual-mode systems that can transition to the vehicle's OBD-II speed output or physical wheel sensors.
Yes. Our GragonGauge and SincoTech lines feature selectable multi-color LED backlighting. Users can cycle through up to seven colors (Red, Green, Blue, Yellow, Purple, Cyan, and Cool White) via a push-button on the rear of the gauge housing or through the dashboard's software settings. This allows for clean visual integration with existing dashboard lighting.
Our multi-function dashboards, like the SincoTech DO908 and DO907, utilize a centralized waterproof sensor distribution box. Sensors for oil temp, water temp, exhaust gas temp (EGT), and oil pressure connect to this box using threaded couplings, which is then routed inside the vehicle via a single harness to the dashboard screen. This simplifies installation, reduces dashboard wiring clutter, and prevents engine bay moisture from entering the passenger compartment.
Our instrumentation is engineered with low-draw stepper motors and efficient LED displays, consuming less than 150mA during peak operation. When the ignition is switched off, they enter a sleep state that draws under 2mA, preventing battery drain during long storage periods. They support operating voltages from 9V to 32V DC, making them suitable for passenger cars, motorcycles, marine applications, and heavy 24V commercial trucks.
Distributors can contact our sales department with their vector logo files (.AI or .EPS format) and specified design layouts. Our engineering department will generate a digital mockup of the dial face or startup screen animation. Once the mockup is approved, we create physical prototype units for validation before proceeding to bulk production.
