Types of Chronograph which measure weapon efficency

 

 

What IS a chronograph?
There are several definitions for the word chronograph, but the kind we are looking at measures the speed of projectiles in flight. Whether they are bullets, arrows, pellets, BBs or rocks shot from a slingshot - as long as they pass through the chronograph sensors, their velocity will be calculated.

What information does the chronograph give you?
The most useful are average velocity, fastest shot, slowest shot and standard deviation between fastest and slowest shots. All of these are great to ensure that your gun is runing at peak performance and more importantly staying within legal limits set.
