Specifications: Voltage: DC 6V Battery (not included): 4*AA battery Working temperature: -30℃-60℃ Accuracy: test error ≤0.5% Measuring range: 0-3000M/S (FPS range 30-9999) Standard tripod can be installed Item size: 330 * 80 * 44mm / 12.99 * 3.15 * 1.73in Item weight: 436 grams / 0.96 pounds
notes: This product is infrared radiation type, the light source has been integrated in the machine, no external light source is needed. Recommended for low-light environments. The darker the ambient light, the better the machine performance. Under outdoor use and strong light conditions, a hood must be added. When measuring the velocity of the projectile at a higher speed. Please take appropriate protective measures. In order to prevent the projectile from rebounding after hitting the machine and causing damage. When installing, pay attention to the marks on the left and right sides of the light bar, and the light bar with lights faces down.
Package includes: 1*Speedometer 3*Heat shrink tube light bar 4*Pure copper rod 1*Screwdriver
