Wind Direction Detector

To make a wind detector, take an empty nasal spray bottle and remove the spray tip and any tubes. You might have to enlarge the hole in the spray tip using a large pin or paper clip. Make sure the inside is completely dry and then fill it with powdered chalk, which can be purchased at any home improvement store. Put the spray tip back on and you’re done.

When out in the woods, simply uncap the bottle and squeeze it to blow a puff of chalk through the spray tip. The chalk is odor-free and carries well in the breeze. I prefer this type of wind indicator because it shows me the air currents over a larger area. Orange colored chalk works well for higher visibility.

    I would caution against using construction marking chalk, as it can and does permanently stain especially if it accidentally dumps out.

    I use unscented talc powder in a spray bottle.

    I love the tip about using line chalk for making a wind detector but the use of the red chalk is not so good. As string chalk goes the red is a permanent marker but the blue is removable or as we hunters say, will wash out of any garment you get chalk on. LOL! I have used the blue for years and find it helpful to add a small bit of rice to it inside the bottle. This helps keep the power dry and the blue when sprayed is almost white and very easy to see.

    Powder wind indicator can’t hold a candle to floaters. I prefer milkweed. Harvest the pods when they are at the end of the growing season and wrap a rubber band around each pod to keep the pod from spreading open. I also take a piece of dental floss or piece old bow string and needle and poke it through the pod to form a small loop which I attach a clip. The pod can be clipped to your coat, pack, or whatever so it’s always easily accessible. I can get an entire season from just a couple pods, and I release floaters almost constantly. Floaters can be seen drifting on tricky air currents for a long distance. Powder is only good for several feet.

    Floaters can be great wind detectors. However, be careful you are not introducing a non-native or invasive species into your hunting area. In some states, it’s a crime, may create long-term problems for the land owner, and ecosystem.

    Floaters are far superior to any powder that may be used. As has been stated, powder only shows for a few feet at best. In my experience the use of floaters has shown wind currents that one would never have expected including changes in every possible direction compared to what the powder indicated. There are many types, including natural products and commercial, available. They may not be as easy to use as squeezing a bottle, but much more revealing. It seems that some of the best ones are so light that they stick to your fingers and won’t let go.

    My preferred wind/breeze indicator is dental floss. I tie a 12 inch length to tip of my upper bow where the string loop is. Dental floss is waterproof and is therefore still effective in a drizzle or steady rain. At any time just a glance at it tattletales what suttle breeze is whisping by. I particularly like it does not require additional hand motion to get check for direction. Which ever method we choose is all in one of the finest joys we all enjoy – hunting a with traditional bow!

    Hi Robin,
    From time to time I thought I had something to share as the tip of the week. Would you please tell me how to go about that?
    Thanks Dan Forystek

    I like the spray bottle tip but i use corn starch rather than chalk. It is finer so produces a better “cloud” to track. No mess, stain, and is very cheap.
