A pocket-sized ultrasonic wind meter designed for long-range shooting. The Calypso Instruments Mini Ballistics measures wind speed and direction, providing live readings or logged data through the compatible Calypso Ballistics App.

QuickDOPE pairs a live wind meter to a ballistics solver that runs on your phone, then tunes that solver to your rifle using the shots you actually fire. Build a stage card in seconds, keep the wind on screen while you work, and push your holds to an e-ink card at the firing line.
A compatible Calypso Instruments Bluetooth meter is required for live sensor readings. App features depend on the connected device and the app version.
