Digital LCD Mini Tachometer (HAN156)

A compact digital tachometer for quick RPM checks on prop-driven RC powerplants. This pocket-sized tool—often listed as the Digital LCD Mini Tachometer or the Micro Digital Tachometer—measures RPM for 2-, 3-, and 4-blade propellers and displays up to four digits with a range up to 32,000 rpm. It operates with a single button and includes a long-lasting 3V lithium battery; auto shut-off helps conserve power, and a low-battery indicator shows when replacement is needed.

Designed for field use, the tachometer slips easily into a pocket or toolkit so RPM checks are quick and convenient between tuning sessions or during maintenance. Its compact form and straightforward operation simplify RPM testing, making it a practical tool for hobbyists tuning engine performance on the bench or in the field.
