My uncle bagged a great deer every year. His trick? He would go out and sit under a tree. Douse himself with a liberal amount of his wife's perfume. Turn a transistor radio on full volume. And then sit back and have a nap. He would rouse himself every 20mins or so just to check around. Invariably, several curious deer had come to investigate. He would just pick a good one and shoot it.
I was a new hunter when all this calling and rattling came into hunting stores in NS. I bought into ALL of it! I bought scents, scent pads, plastic antlers (guaranteed to sound more real than real ones), doe in heat bleat cans, grunt tubes, you name it. It was too bad no one could teach me how to use it. I just read the directions that came with the antlers and off I went. It said to whack the antlers hard to start, kick your feet around on the ground, and toss in a grunt or too, and every dominant buck in the area would be visiting you.
Off I went. Armed with all the newest, bestest gear and an old .303. Found a nice clearing. Put my back against a tree at the edge of it (didn't bother about wind, cuz I had cover scents on an stuff), waited for the woods to calm down, and started my first EVER rattle! I did this off and on every few minutes for about an hour and the sun started to go down. So, I packed up my gear, stood up, walked around the tree and busted the biggest whitetail buck I had ever seen!! Like 3 feet from me. I am guessing he couldn't figure out what the hell was in front of him!! He could have been there all day, for all I knew.
Now, I don't worry about all that stuff. My wife hunts in hot pink yoga pants or a hot pink warm-up jacket he has worn most of the day. We only have Camo cuz it goes on sale more often than other outdoor "technical" clothing, and does so earlier in the season.
