Looks like a nifty product and all, but similar lights were developed and sold for many years already, LOL.
Interesting article. I am not sure I agree with all of it, but it hits some major points. For an animal that supposedly cannot see at night, hogs are very good at running at fully speed and avoiding obstacles, something that humans can't do, despite being equated with comparable night vision to humans. I am not sure pigs are as nearsighted as claimed, either, but that is something not readily observed empirically.
100% with you on both subjects.
Pigs see just fine out to 150 yds or so. I would hardly consider that 'near sighted'.
As for low light/night vision....they can navigate and even run full speed through a pine forest where I live. I sure as hell can't do that.
Pretty sure the pigs have not 'memorized' the location of each tree or developed 'echolocation' like bats. So that really only leaves eyesight....right.
There are a lot of things to consider when discussing a pigs 'eyesight'. IMO.....what is observed of them in the field is often mistaken or misinterpreted.
For instance... if you are slowly walking up on a pig that is feeding in 30" high wheat, you'll probably get up pretty close to it. It ISN'T because the pig has 'poor' vision, it is because his head is never more than 20" high unless he lifts it to see more. You are observing the animal from a perspective of 60" high (or better). You can clearly see the pig, it just can't see you. Doesn't mean it has poor vision.
Hogs tend to spot 'movement' easily. Stationary objects do not seem to be as readily detected BUT hogs are keen to pick up anything NEW in an area they are familiar with.
How they react (or not) in either circumstance can vary with circumstance. So all things must be considered before declaring a pig this or that.
Also... many of these so called 'studies' are conducted under very controlled conditions and might not account for things such as 'alertness'. A calm, un-pressured hog is quite a different animal from one that is on high alert and using any one of its senses to its full ability.
