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

The cartridges are used in the Dead Down Wind Scout, a novel way to track wind direction while hunting. There are lots of products that will track a breeze, but this will identify an air current that you may not even realize is there!

Works pretty well (squeeze slowly) Not sure how long the battery lasts cause it never ran out. Wish the smoke carried a little farther but still happy with it. Also not sure how long the smoke cartridge lasts cause it never ran out either.

It either is a horrible product or it is defective. Can only see the vapor if it is in perfect lighting.

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

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.
