First Impressions of Sierra International 189913 Smartach Tachometer For Diesel & Gasoline Fuel
The Sierra International 189913 Smartach Tachometer For Diesel & Gasoline Fuel promises to be a versatile solution for anyone needing accurate RPM readings on engines equipped with alternators. Boasting compatibility with both diesel and gasoline engines, a large LCD display, and a claimed 0.05% accuracy, it certainly piqued my interest. This tachometer aims to simplify engine diagnostics and monitoring for a wide range of users.
As someone with over a decade of experience in the outdoor and tactical gear industry, my expertise often extends to vehicular applications. I needed a reliable tachometer to diagnose intermittent performance issues in my aging diesel-powered off-road vehicle. I was tired of relying on inaccurate and difficult-to-read gauges.
Upon unboxing, I was immediately impressed by the Sierra unit’s robust feel and the included hard-shell carrying case. The large display looked clear and easy to read, even in potentially harsh outdoor conditions. It certainly felt more professional than the cheaper, permanently-mounted tachometers I’d used in the past.
