Calypso Instruments makes ultrasonic wind meters and compact weather sensors that give shooters accurate environmental data right at the firing line. Their ballistic-focused devices were developed to feed reliable wind and weather information directly into modern solvers, so you spend less time punching numbers into a phone and more time actually shooting.
We stock their equipment at No Boring Guns because European shooters have limited access to quality ballistic weather instruments without dealing with individual imports or unpredictable pricing. Selected Calypso wind meters integrate via Bluetooth with popular ballistic apps, so wind speed and direction flow straight into your firing solution instead of being copied over by hand.
Calypso Compact Weather Stations
The Calypso Ultrasonic Portable Mini and Mini AB wind meters are the core products for long range shooting. These pocket-sized units use solid-state ultrasonic sensors with no moving parts to measure wind speed and direction, then send that data via Bluetooth to the Anemotracker app and compatible ballistic software such as Applied Ballistics on supported devices. You get live wind input at your position without retyping values every time conditions shift.
The Calypso WeatherDot is a small, fixed sensor that focuses on temperature, humidity and barometric pressure rather than wind. It can be tripod- or rail-mounted near your firing point while your phone monitors conditions over Bluetooth. Used together, a Mini wind meter for wind data and a WeatherDot for atmospheric pressure and temperature give you the full set of environmental inputs your solver needs.
Calypso Wind Measurement Tools
The ultrasonic anemometer technology in Calypso instruments is built for detailed wind characterization. Fast update rates show real-time gusts and lulls instead of just slow averages, which helps when you are trying to break the shot in a stable part of the wind cycle. With the Applied Ballistics compatible variants, wind speed and direction feed directly into your ballistic app, cutting out transcription errors and speeding up corrections between targets or stages.
