1. Shooting speed tester: Features an aluminum alloy housing and stainless steel support rod. It measures speed, energy, speed energy, displays recordings, and calculates the average value. Simple, durable, and practical. 2. Builtin quality microcontroller: Accurately measures the flight speed of various projectiles ranging from 1–2000 MPS (5–6500 FPS), with stable performance and minimal error. 3. Strong light adaptability: adaptable to indoor and outdoor ambient light. Performance improves in darker conditions, making it suitable for both day and night use. Stores up to 80 records and displays the average value. 4. Large sensor range: Equipped with a wide effective sensor area for easy operation and sensitivity. Ideal for measuring the ballistic speed of table tennis, badminton, arrows, and bows, as well as for physics acceleration experiments, projectile fall experiments, and speed measurements.
