The 60-second version: A shot timer measures the time from a start beep to every shot you fire, turning a vague “that felt fast” into hard numbers — your draw, the splits between shots, your reload. There are really only two kinds: a dedicated hardware buzzer ($100-200) and a phone app. You do not need to spend a cent to start, because the single most useful timer for most people is the free AirsoftShotTimer app already sitting in your pocket — and it’s tuned to pick up the quiet pop of an airsoft gun and even dry-fire clicks that generic timer apps miss. Set it to random delay, run one draw drill tonight, and let the data tell you what to fix. The rest of this guide explains what every number means, the five drills worth timing, and how to read your results.
