I like to use dogs, but have a lot of sucess with stalking.
Find their sign then stalk slow and quiet, keep downwind.
Pigs make a lot of noise so aren' t too hard to locate.
Their eyesight is not great, but their hearing and sense of smell are incredibly good.
Where I' ve hunted, the pigs move around a lot so hunting from a stand, wouldn' t work real good. I guess you could stake out a food supply.
A few places I' ve hunted have been on ranchs. When they loose an animal (Cow/sheep etc.) they lay the carcass on the bush edge, when you see evidence of pigs feeding, you can ambush or stake-out.
In places where water is scarce the same could work on waterholes.
Good luck with your pig hunt.
