  • The ProChrono Digital chronograph operates on the principle of measuring
    the time it takes for an object to travel from the first projectile sensor to
    the second projectile sensor.
  • The sensors, mounted internally in the case, gather light through the two rectangular openings in the top of the case.
  • The sensors are actually specially designed electromechanical devices that
    can detect changes in light intensity that occur when a projectile interrupts
    light rays shining into a sensor when it passes over the opening above.
  • If you can imagine looking up at the sky through a tube, you will gain an
    understanding of what the sensors see.
  • The only light they see is what is directly above them. Any light blockage caused by an object passing over them is converted to a signal that is detected by the ProChrono Digital.
  • The chronograph measures the elapsed time between the light interruptions a
    projectile makes as it travels over the front, and then the rear sensor.
  • It then converts this time into velocity and displays it on it’s front-mounted LCD
  • Store 9 shot strings with up to 99 shots each in power down memory.
  • Review each velocity and shot string data which includes average velocity, standard deviation, and extreme spread.
  • Delete an individual shot or entire string with the touch of a button.

  • Customize your system with optional accessories. Only pay for the features you need.
