This topic was on Chris Miller's board sometime back. Alot of people agreed that barometric pressure, did effect scenting conditions. However, unlike the old man told you, their thoughts were exactly opposite. They thought if it was over 30, it was bad scenting conditions. Someone even went as far to say, that they would not even get their dogs out of the kennel, if it was over 30. Nothing was said about its effects on the rabbits ears.
After reading all the opinions from the people, I started watching this myself. Every time I go hunting, I check before I leave the house, and when I get back. Alot of the time, I will also call home (while hunting)and ask my wife if it has changed, and what it is at that time. I know, she thinks I'm crazy too.
My findings are as follows:
When the pressure is above 30.00, the scenting is not as good. It don't matter if it is wet or dry, if the pressure is high.
When it is above 30.35, it makes good dogs look stupid. Its those days when you see a rabbit, put the dogs on it, and they just can't run it.
The best running day I've had this year, was with a falling barometric pressure. It started out at 30.04 when I left home. When I called home it was 30.02 About 3 hours later (when I got home)it was 29.92 Later the same evening it went to 29.84
So I believe when it is falling, it is the best, especially if it is below 30.00
I go hunting every opportunity that I have. If the pressure is up, I still go. I won't let high pressure keep me home. If it is low or falling, I go with alot more enthusiasm.
Hope this helps,
Bart
