The Firefly Electronic Wind Detector is unlike any wind meter you have ever used. Employing the most advanced, patent pending, wind flow technology available, the Firefly is extremely sensitive and can measure wind well beyond human perception of wind movement. In just three seconds, over 1,500 wind measurements are taken to determine the absolute wind direction with wind velocities as low as 1” per second. Wind direction is shown with bright red LED lights. Using two AAA batteries the lightweight, handheld Firefly, includes a weather resistant cap and is available with a lanyard and hard or soft shell protective cases. It will fit easily into your pocket or your shell bag.
For all hunters, this is an absolute element of your next hunt. Waterfowlers can use the meter before setting decoys and big game and predator hunters can use this to make sure they are downwind. This is not like a typical wind direction meter that has to have a perceivable wind to be usable. The Firefly can detect the lightest breeze and thermal. The bright LED readout is easy to read in all light conditions and feedback is quick.
The Firefly uses state-of-the-art advanced flow technology. It is small in the hand, but provides high quality and very accurate output. The screw-on cap provides a water resistant unit that is built to last.
Reliability is built in. There is no chance for an erroneous measurement. If one LED is lit, you know the absolute wind direction; if two lights are lit, then the Firefly is interpreting some variability and the direction is between the lights. If three lights are showing, variability is enough to provide the general direction. A compass on the top of the unit verifies the wind direction. The two AAA batteries provide up to 500 wind dirction measurements.
At $59.00 you get one heck of a high-tech piece of equipment. Other options are available as the Firefly comes in matte black, G-1 Vista or Mathews Lost Camo. A retractable lanyard and protective case are also available separately or in cost saving combo packages.
Retractable lanyard $24.95
This is a product I highly recommend. It is quick and easy to use and takes the guess work out of wind direction in all types of light. I really like the quickness and accuracy of the readout. I tested the firelfy against two other wind direction meters and neither could show wind direction in very light winds. I also was impressed that I could get a wind reading within some structure. So in the woods I can see this as very advantageous to hunters.
