If you're running through a field, you're the only ~1.7m tall, dark, moving object against a light or medium-colored background. Of course you're going to be spotted, and it doesn't take an 8x scope to do it. I'd be much more afraid of players that see me and set up ambushes outside of the buildings I investigate. You know why? Because that's what I do. I spot people that have no clue how to behave in a combat environment and just glad-ass their way across a field dreaming about zombies when the real threat are other players that want your beans, and I let them try to play zombie apocalypse savant and pop everything with their Winchester and I move to a position where I can see inside a building with only one exit. I watch that building, and I watch the gear spawns inside of it. That nitwit will feel so safe after capping all of the zombies that he'll waltz in there and sit down staring at the gear while I line up a shot on his head with my M16. Good fight, mate, I'm out one bullet and I get your beans. I was probably just sitting next to a bush, and you probably would have seen me if you had taken 5 seconds to scan tree lines. I probably wouldn't have seen you if you had run through a tree line yourself. Play smart, you won't die. Your pal, 50+ hours on a single life and counting, Mac.
