English: A bank of 10metre airgun targets manufactured by Sport Quantum.
Sport Quantum differ from most Electronic Target Systems in using a digital display behind a perspex shield. This allows the display of arbitrary targets and images, including moving targets. The impact on the perspex shield is detected by an array of piezoelectric sensors.
Most electronic target systems detect the passing of the bullet through the target frame with a microphone array or laser based grid, neither of which involves physical contact with the projectile. A bullet or pellet catcher is placed behind the target frame.
