The Hangar 9 ® Micro Digital Tachometer was developed with the latest technology. This handy tuning tool can measure the speed of any engine equipped with 2-, 3-, or 4-blade propellers. The speed is displayed in up to four digits, with a range of up to 32,000 revolutions per minute. A long-lasting 3V 220mAh lithium battery is included in the price. The Micro Digital Tachometer Auto-Shut-Off function extends battery life, and a Low-battery icon indicates when the battery needs changing. It is also small enough to fit easily in your pocket.
