Dead Down Wind Wind Scout Wind Detector | Odorless Wind Direction Indicator, Longer Range Visibility, Detects Subtle Breezes (Wind Detector Refill)

Great concept but I could not get these to work on a consistently. Hit or miss.When they work they are nice. Unfortunately they don't work most of the time. Charged and put new cartridge and still no better.Would be cheaper to buy e-cig. Would be smaller and eork like a champ.

Have used a lot of different kinds of hunting scent killer products but like this one the best.

Like everything about it, super easy to use and gives very good amount of vapor.

Good device to determine the wind's direction. Make sure to replace the cap after each use. Failure to replace it will cause the cartridge to empty.

Wind direction is very important in hunting feral hogs. This device is easy to use and the wind direction is know. Very good device!
