We have no idea when they help us or when they don't
It's a pretty steadfast rule in Physics that heat rises, no?
If I am 98deg in my stand.....and the ambient air temp is 30deg.......there's a "fair" chance my thermal is rising above the level of the deer's noses in my immediate area.
HOW can applying the knowledge of this law NOT help me?
Sure, but how long does it take to cool off to ambient temperature? Not very long if I was to guess. W/out the aid of body temperature to keep it @ 98*, it's gonna cool off rapidly. Then that law does not apply. If there is a sinking thermal, you're busted. Your scent is gonna cool off and sink w/ the thermal. My way of thinking anyway.
Tony, yes, it plays a large part in my hunting.I LOVE hunting ridge tops on high pressure mornings. That thermal shoots almost straight up. I use those wind puffers to see what the thermals are doing, and it's usually pretty interesting.
