Cirrus has changed the wind detection market for the first time in decades. The patent pending design allows the user to puff a vapor-like cloud into the air and detect the slightest wind or thermal currents. The benefit is thousands of puffs per cartridge, USB rechargeable, lightweight and minimal user movement. Changes for the 2018 model include red and white LEDs to see wind and thermals in total darkness and a built-in portable charging bank.
The Cirrus Wind Indicator is great for checking wall penetrations in Building Performance applications. (eg chases, outlet and switch boxes, windows, etc.) It generates as much smoke as its competitors but is more convenient and leak free, no need for burning "smoke sticks" either. It does not produce enough smoke to fill a room or building like a theatrical smoke generator, but for tracing air patterns close to surfaces/penetrations, it works great.
