Precision Ballistic Environmental Sensing — Zero Moving Parts, Complete Atmospheric Data.

The Calypso Mini All-in-One Ballistics Meter builds upon Calypso’s proven solid-state ultrasonic technology, packing real-time wind vectoring, barometric pressure, ambient temperature, and relative humidity into a single ultra-compact, pocket-sized housing.

Engineered for precision rifle shooters, long-range competitors, and snipers, the Mini All-in-One eliminates mechanical impellers and weather vanes that freeze, lag, or break. 

With no moving bearings or spinning cups to maintain, it delivers immediate, true continuous wind and atmospheric readings in extreme field conditions.
