DATASHOT is a free acoustic shot timer that runs in your browser. It uses your device's microphone to detect gunshots and records split times with millisecond precision — no app download required. It works for USPSA, IPSC, IDPA, 3-Gun, Steel Challenge, and dry-fire training.

Can I use DATASHOT for dry-fire training?

Yes. DATASHOT works for dry-fire practice with snap caps or a laser training pistol. The acoustic sensitivity can be adjusted to detect quieter sounds like magazine changes, snap cap clicks, or hand claps.

DATASHOT is completely free to use. You can create a free account to save your session history, review split times, and track your progress over time.

How accurate is DATASHOT compared to a dedicated shot timer?

DATASHOT uses short-term energy entropy analysis to detect shots with sub-frame (≈12ms) precision via the Web Audio API. In controlled testing at the range, split times are within ±15ms of dedicated hardware timers like the PACT Club Timer or CED7000.

What is a par time in a shot timer?

Par time is a target time goal for a shooting drill. DATASHOT's par time feature highlights your total run time in red if you exceed the par, and displays a clear indicator on the split list — helping you train to a specific time standard.
