"When you are hunting big game or predators, how important is wind direction? If you are like me, wind is everything and the primary consideration when selecting a stand on a whitetail hunt. The same goes for determining an approach on a bulging bull elk. Ditto for calling coyotes. No matter how careful one is with scent elimination, it is always best to put the wind in your favor. Of course, that is sometimes easier said than done. Wind direction is not always consistent. The topography of the terrain can redirect wind and cause swirling. I have a favorite stand in prime whitetail country that is on the side of a wooded ridge. When the wind blows from the southwest, the wind direction at this stand is northeast. I can look up and see the clouds going northeast and feel the wind going the opposite direction.
Thermals are an entirely different issue. Combine thermals and wind direction and who knows what direction your scent might be blowing. And thermals change at a flip of a switch as the sun comes up or goes down. I always used to carry a container of powder to assess wind direction. It was better than nothing but I never felt like it helped unless there was a pretty significant breeze. The weight of the powder caused it to fall out of the air. And, I couldn’t see the powder in the dark.
Now I have a Firefly! This electronic wind detector reports wind direction at the push of a button. It’s easy to use and visible in the dark as it reports the wind direction with flashing LED lights. Best of all, it can detect wind currents and thermals that are undetectable to humans! Here’s how it works. Firefly takes 64 readings per second for three seconds. The sophisticated electronics in Firefly analyze this information and, after the three seconds, report the findings via eight LED lights. For five seconds, you’ll get a second by second report. One light means a definitive wind direction. Two lights means the direction is between these two LED lights. Yes, it is that precise! Three lights tell you that the wind direction is variable. All the lights will flash if there is an error.
I used my Firefly extensively this fall on both an elk hunt and during several whitetail trips to Iowa. This is one very impressive product! It flat out works! I didn’t always like what it was telling me, but I sure was glad I had the information. In one situation it showed a current headed out into the food plot I was covering. This current was counter to the wind and only occasional. I chose to use this to test Firefly. The first doe that walked into the food plot stuck her nose up in the air as soon as she stepped in. I couldn’t believe it! She turned and left. That experience and several similar experiences throughout the course of the season sold me on Firefly."

"When I took this bear, we were hunting in a heavily wooded area in northern Minnesota. I had checked both the bear stand wind currents as well as the directional flow near the base of my shooting lane. There was a significant airflow difference between the stand and the bottom of the down hill bear trail. The Bear worked its way through the trail from west to east (into the wind) while I was getting several wind shifts and swirls on my stand on the ridge. Having recognized those subtle differences I was able to focus my efforts accordingly and attain my bear just days before the end of the season. Thanks Much “Team Firefly !!!!! "
