Okay, the bottom line is, you don’t need a chronograph. If all you do is shoot, you never need to use a chronograph for anything. But, if you want to get the optimum performance from your airgun and if you want to diagnose the health of your airgun, a chronograph is an essential piece of equipment.
Imagine a doctor without a stethoscope. He’s still a doctor and he can still do lots of things; but a major tool has been taken away, and there’s no way he can get around not having it. That’s you without a chronograph. Allow me to explain.
Let’s say that you want to get into the world of precharged airguns, and let’s say you’ve read enough to understand that you don’t just fill them to their maximum fill pressure and start shooting. Oh, you can do that, and it’ll work, but you’ll never know how well it works unless you can diagnose how the gun performs. Let me illustrate with a story.
