Universal Digital Tach II

The Universal Digital Tach II is a precision tachometer engineered for small-engine diagnostics, tuning, and real-time RPM monitoring across magneto and electronic ignition systems. Designed for mechanics, technicians, and powersports enthusiasts, this digital unit delivers fast, accurate readings up to 15,000 RPM—making it essential for carburetor tuning, engine synchronization, and troubleshooting on equipment ranging from motorcycles and ATVs to small generators and lawn equipment.

This tachometer features a bright digital display mounted in a 2-1/4 inch square gray face, offering clear visibility in varied lighting conditions. The unit operates on a single 9V battery, ensuring portability and field readiness without requiring a permanent power source. Its design accommodates both magneto-based ignition systems and modern electronic ignitions, using non-contact sensing to detect RPM signals reliably and without introducing load into the engine's electrical system. The compact footprint (4.3 x 2.4 x 6.9 inches) and lightweight construction (0.87 lbs) make it equally at home on a workbench or in a mobile service kit.

Technicians benefit most from the Universal Digital Tach II when performing idle speed adjustment, ignition timing verification, and synchronization on multi-cylinder engines. The included mount and hardware allow bracket installation on test benches or temporary placement near the engine's ignition source. Compatibility with both magneto and electronic ignitions eliminates the need for multiple tools, reducing inventory and simplifying diagnostics across vintage and contemporary powerplants. Whether you're in a professional shop or maintaining personal equipment, this digital tachometer delivers the accuracy and versatility required for critical tuning decisions.
