Firefly is designed to determine wind direction even when there is no perceptible wind at all! Firefly can determine wind drifts and thermals down to 1” per second.
It uses patented technology to take 512 readings per second, which it then analyzes to give you the most accurate readings of any wind detection device- even with winds undetectable to human.
Firefly is the first electronic wind detector.
Firefly works but don't take our word for it. Try it for 30 days, if it doesn't meet your expectations feel free to return it for a full refund.
Big game animals and predators survive by using their well developed sense of smell. The best way to avoid detection is to use the wind or thermals to your advantage
To do so, you must know the wind direction. Nothing detects wind direction like a Firefly Electronic Wind Detector and should be a part of every hunters hunting equipment
