They go into an area. They interview witnesses. In many cases they have a little town meeting. Now they triangulate their favorite interviews and try to pick a spot in the middle. So far they have heard tree knocks, howls, walking, whistling and talking. The last two things were very recently mentioned, and instead of being evidence of people in the woods, were presented as evidence of Bigfoots too! There is no anti evidence! Everything is proof! There's a dissenter, they give her 15 seconds to say she doesn't agree, and then show at length the other three dismissing her viewpoint. You just know if the show continues another season, they'll insert Matt saying "Not her again, look.." right after she questions something.
They have personal cameras on their faces. They have hand held heat signature cameras. They have at least two camera people filming them. This stuff is par for the course in TV ghost hunting. But there's a big difference between hunting animals and ghosts. In ghosts, there's a specific area usually no bigger than a warehouse where there's lots of activity. In looking for animals, the animal might wander miles, upon miles and try to avoid humans. This is why most shows pick an area and lay Camera traps. But this show isn't really about finding anything. It's about making four people the Beatles of Bigfoot hunting.
They sort of act like forests everywhere are teeming with Bigfoots. Unlike shows like Ghost hunters where they occasionally tell people they didn't find anything, you get the feeling these guys could go into Central Park NYC and come away convinced they found some.
Also, that town meeting they have would alert fakers from miles around it's time to start some faking! They're not exactly stealthily blowing into town, are they?
Another comparison to Ghost Hunters is you'll have the two lead investigators almost always temper any beliefs with "it's believed that", or "it's theorized" On this show it's "We know" or It's been proved" and very often even "I discovered" or "I was the first...".
What they have proved is that Ego maniacs do indeed wander the forests of North America!
It is great TV! A modern day Ahab shows up with his crew and looks for the great White Bigfoot. Yelling and screaming, and declaring himself master of all.
