lol yes, that is a common problem in SAR: the dogs are great, the handlers, not so much haha! Some teams are different than others as far as age and physical ability goes. Since MI is fairly flat you don't need to be able to climb mountains and all that. Just stay on your feet and walk all day. You do have to be able to clear 160 acres in 2 hours though (in typical MI terrain). For some people that can be a challenge, especially if you don't have a dog who ranges from you very far. That area and timeline is just the basics. Our searches usually last for 8-12 hrs with very little break time. It's a lot of walking and walking and walking and by the end of the day you have probably covered 400+ acres. With the shape I am in, I could not do SAR in a state like CO or one that is similarly mountainous but I can walk for a long time with no issues. It just can't be up a side of a mountain ;p
Cone of scent (or scent cone) is used to describe what the scent picture looks like. For example, picture a person standing with the wind in their face. Skin cells are constantly falling off their body and dispersing in the air around them. With the wind in their face, the scent picture (or scent cone) would be very concentrated right at the person, then it would slowly expand out behind the person, traveling with the wind.

So, your job as a handler is to put the dog in a position that would be down wind of a victim. In training, you train your dog to work perpendicular to the wind, making sweeps. When the dog gets into the scent cone, it will do a "head pop", meaning its head will come up and turn into the direction it catches the scent from, then it will sweep back and forth, working the scent cone edges until it gets to the source of the scent
With training, the dogs learn pretty fast to work areas that would catch scent, which are called scent rails. Those are things like pools of water, hedges, fence lines, downed trees, holes in the ground, sun vs shade (depending on the time of day) and so forth. So you let the dog go and it goes to all these places that would likely hold scent until it finds scent, then it works that scent to the most concentrated source, which is at the victim. It is very cool to watch a naturally talented trained scent dog.
ETA: even if you don't find your victim in the area you are searching, if you pay attention to the dog's body language and mark on your map whenever the dog gets scent behavior or a head pop, you can narrow down where the missing person might be based on the direction the wind is traveling, time of day, terrain, etc. So, if the person is a half mile away and you have good wind, you wouldn't want to ignore a subtle head pop even if the dog loses the scent. Mark it down then look at all your subtle head pops and you can see where the wind is taking the dispersed scent from.
