I can't vouch for it, exactly, but do know animals get used to what is in their environment.
I've never tried it, so I can't say one way or the other, but it certainly sounds counter-intuitive to me. Novel...but it 'assumes' a lot.
Yes, some animals can/will 'acclimate' to conditions they encounter, but there is a high end to that.
One of the things the method assumes/requires is that the animal repeatedly encounter the (strong) scent. Lets suppose for arguments sake we are talking about Deer or Feral Hogs.
In order for either animal to 'accept' the (strong) scent as non-threatening:
1. It must NOT have first had an associative experience (that was bad) or not possess an innate 'instinct' to flee because of it. In other words...it just doesn't know. Juvenile Deer or Hogs 'might' fall into that category.
OR
2. It must (over time) develop a 'trust' of the scent....borne directly from NOT experiencing a threat (even IF it has previously.... or has 'instinct' telling it so). That would be 'acclimation' and would normally occur only after repeated circumstances wherein nothing 'bad' happened to the animal.
For this to work at a particular spot... would require repeated visits by the same animal (under those conditions). Not a entirely unreasonable expectation. I have a resident Deer Herd on my property and sometimes Hogs revisit a site, so they might be there long enough to become conditioned.
But I cant imagine any non-resident Bucks (especially mature ones) or traveling Boar Hogs to stick around long enough for this to work.
Its just so much easier to minimize your scent to begin with.
Except in really remote areas....most of the animals we pursue are exposed to human scent, sounds or sight and come to learn and accept certain human activities. And within certain 'bounds' these things do not disturb or concern the animals. But if you 'push' things (get too close, make too much noise, etc)...it all falls apart.
Yes, if we are careful....over time you can condition certain animals to accept certain levels of certain things (hogs under hog lights, deer accepting certain sounds) but there is always a high end. So why bother trying to do something that is more difficult to achieve than just taking precautions.
IMO....learning your prey and becoming a more skilled hunter will pay more dividends than trying to change the natural habits of the animal.
