Yes. Use of a good cigar for constant output helps. Or a small smoke machine. But for $11/can, Windicator® has the best ability to demonstrate how vapor will travel and where it goes. It is also helpful for placement of BirdBuffer during business hours. Remember, vapor comes out of the BirdBuffer® and then disperses – up, down, and sideways – covering a large area right away.
Can wind direction be determined without a can of Windicator®?
