3-3/4 in S/C II Mini Monster Tach

The 3-3/4 in S/C II Mini Monster Tach by AUTOMETER is a compact tachometer designed for serious gear heads and engine builders who need real-time RPM monitoring during dyno pulls, track days, and street performance work. This gauge is particularly useful in vehicles with limited dashboard space or where a dedicated engine bay gauge cluster is preferred.

Built on AUTOMETER's proven S/C II platform, the Mini Monster Tach utilizes electric impulse sensing to accurately capture engine speed data directly from ignition signals or via a dedicated tach lead. This design eliminates mechanical cable wear and calibration drift over time, ensuring reliable performance. The sealed construction protects internal mechanisms from vibration, engine bay heat, and road debris.

Ideal for turbocharged, supercharged, and naturally aspirated builds, this gauge provides dependable RPM feedback independent of factory instrumentation. Its compact dimensions allow for flush mounting in tight engine compartments, center consoles, or custom gauge panels, making it a versatile choice for performance diagnostics.
