Multifunctional for Speed Meter Ball Velocity

Multifunctional for Speed Meter Ball Velocity Description

12 sets of infrared sensor heads before and after, to avoid leak detection
Four-sided hollow design to prevent airflow interference
Simultaneously record 40 sets of speed and energy data for easy viewing

Working voltage: DC3.7-4.2VAlready builtlithium battery)
