This is were I left off a while back and I had promised to talk about air currents for hunting predators.
Wile hunting it does not hurt to try and keep your body sent free. Your hunting partners will be glad you did. But to a coyote or fox it does not matter. They will smell you no matter how clean you are. Of course the less you stink can help you a little by giving you a few more seconds until they pick up your sent.
How to use air currents and wind is the best thing to help a hunter.
It is pretty simple to read the wind directions. Most of the time you can feel it if you pay attention. Or you could use the puff bottle wind detector like deer hunters use if you have problems. What ever way you chose this is important that you know the wind direction. The next thing is air currents also known as ground currents. Air currents run close to the ground day and night and in big temperature changes you can even feel the air currents run a different way then the wind is going Air currents have little to do with wind direction unless you have hi winds. When the winds get stronger it can start to affect air currents. If wind is strong enough it will push air currents the same direction as the wind.
But under most hunting conditions the wind is not strong enough. Unless you are hunting in over 20 mph winds. The best way to read air currents is to look at the ground shape. Ground currents flow like water does. If you look at how water on a mountain flows you would see the same path air currents will take. The reason being all air currents are always either warmer or cooler then the air temperature or ground temperature. Cool air flows down the hill just like water would. Warm air will flow up hill but will not take the exact same path as water does down hill but close enough that you can us it in you stand location. I know this may seam hard for some people to understand , but if you think how water would flow over the ground it gets simple.
Good luck hunting.
