does anyone have a clue on how WIDE your scent carries out. I understand that your scent can travel a long way, but how wide does it fan out. For instance if your body is 3 ft. wide does it roughly fan out that much or does it widen out like a funnel. Hope this doesnt come across as a stupid question, by watching the few deer that did catch my scent, they were directly in line with me and the wind when they did

Picture a funnel that starts very small and gets bigger the farther up it goes. Think a ever widening cone .The faster the wind the longer the funnel is to achieve the same width as a slower wind that allows the scent to spread out sooner or in less distance. So in fact a stiff 15 mph wind is less likely to get you winded at say 30 yards down wind than say a 3 or 4 MPH wind that will get you winded at say 20 yards down wind if you where hunt a tree stand say just 16ft above them. These are estimates for example it would take wind tunnel and many computations to know exactly how you scent would disperse and then you have to throw in things like trees and terrain that changes air flow.

I think its a pretty fine line. I always picture it as being as wide as your body. Not sure if it is or not. but I've had deer stop down wind of me right in line with my scent stream only to take a couple of steps and get past the wind and calm down to be just fine. As said above I think there are lots of variables.

Just think of when you smell a skunk. All that smell comes from one little spot but it covers a huge area. Most odors do the same thing.

uncork a bottle of perfume in the corner center of a still room .... wont be long before that scent can be smelled from anywhere in the room. The molecules of the perfume see the room as a balloon and disperse to occupy every bit of that balloon.
Take it outside ... and add wind .... the perfume will still see the entire world as a balloon and disperse to occupy every inch of space possible. The wind will carry those molecules in a given direction but they will still be expanding their area. Subtle wind changes or swirls will really effect where those molecules end up.
I dont think a funnel shape would be an accurate way to describe what is happening .... picture our recent oil disaster. The oil was coming from a single point in space and was being carried by water and its currents. Bits and pieces of that oil ended up in some of the dangdest spots and the biggest area of it was an ever growing "blob" moving a certain direction that changed with the currents but continued to grown in size.
Replace the oil with human scent ... the water with air ... and the current with wind.
How many molecules it takes to freak a deer out is the big question.

Don't forget the thermo currents. I've found over the years that the stronger the wind, the less likely you'll be detected. But wind direction is not always the only factor to consider.
As for how much it takes to blow deer out, sometimes they don't blow out no matter what, so figure out what causes that and you'll be famous. On the flip side, if you like to hunt 360, are you sure which direction a deer coming in will travel. Sometimes it helps to be lucky?

Their is a reason why you should stay down wind of deer. If the perfume theory is accurate, then staying down wind would be pointless.

I would say relative humidity & wind dictate scent dispersal.

I've read it several times, and still don't get it. At least not how it applies to deer hunting. |
