I classified the types of Bigfoot researchers into four categories but keep in mind these are generalizations and there are all kinds of people who are willing to get out to find proof that Bigfoot exists. Some may deviate from these descriptions but if you look into it, you will find that many do not. These searchers are camp, road, trail and deep forest searchers.
Road searchers are probably my least favorite. They drive at night to certain locations, and get out and look for Sasquatch. These folks will also have IR and possibly FLIR cameras as they walk around. They listen for wood knocks, look for eye shine, and generally search for bigfoot. The problem is they often do not leave the roads. If they do leave the road it will be on a game trail and usually one a few hundred yards away from the road. Their thinking is that if they walk the road, it's quieter than the vehicle which is true. They do not get far enough into the bush to find what they're looking for. The vehicle gets them quite a distance but roadways no matter how primitive are the least likely place to find Bigfoot. Road searchers will also go out in day time to look for more evidence. Oddly these researchers most often find "evidence" after the fact. These are the ones that find something after they review their footage. The theory being that bigfoot are so good at hiding that they cannot always be seen by the naked eye at the time. This is where the word pareidolia comes into play..
Trail searchers are the ones that hike to areas using common trails. They spend a night or two searching and might hike to another location search more and hike out. Sometimes they camp at their locations and sometimes they don't. They often have cameras such as IR or FLIR and sometimes use trail cams. They are at least getting out there farther. They range from 1 to 4 miles in most cases. I cannot speak to much concerning their ability to search at night but I do know that they rarely travel far from camp for safety reasons which is a good idea unless you have experience living in the wilderness.
Deep forest researchers have the opportunity to be the most successful searchers. They pack into an area, camp, hike further in camp some more and make their searches at night for the most part. Due to human inability to hike in the dark safely, they should always relocate in the daytime. These researchers will often span 20 miles or more. They are a rare breed. There will only be one to three people out in the area allowing for a better chance of sighting the curious ones. Often they will follow a trail, maybe a game trail and sometimes will bypass trails all together in order to find Sasquatch. Their goal is to get deeper into the wilderness to find Sasquatch. After all, if I were wanting to avoid humans, I would avoid the roadways and their trails.
Please keep in mind that these are generalizations of people's style for going into the wilderness to search for an unknown creature. At this point there is no wrong way or right way to search for Sasquatch but common sense goes a long way in finding anything in the wilderness. As an example, a person carrying a camera in front of them all the time is less likely to notice wildlife and trail oddities than one who is walking along quietly. That person with the camera is concentrating on where they are walking as well as their equipment and their shot. You can argue that if you do it enough it becomes second nature but that does not hold true. The person without may have to concentrate on where they are walking but also concentrates on what they are seeing, smelling, and hearing. This cannot always be said of the person with a camera.
