You have to know the wind direction to avoid spooking game and Smoke Detector provides perfect readings every time with the accuracy of a smoke cloud. Super light air currents are hard to detect and can end a hunt quickly, but Smoke Detectors odorless cloud is ultra sensitive and shows air movement hunters cant feel. Low-light conditions are prime time for game movement as well as getting to your stand, and the highly reflective cloud is easy to see even in low visibility conditions. Unlike heavy powders, Smoke Detector floats freely in the air and doesnt fall straight down. Simple to use, doesnt clog and 100% accurate wind reading every time.
