I don't mind at all taking a walking shot on a deer if he's close, like around 6-15 yards away. I also use to have my bows unbelievably quiet too, which helps in reducing any neg reactions to the sound. Today I'm not sure if I'd take a moving shot or not, but back in the day I had my motto of "If it's brown, it's down". LOL!
Most often I never make a noise. If I'm rifle hunting and a shooter is walking at a far away distance or is having their head down too long, I'll just whistle to get them to stop or prop their head up. Make the whistle just loud enough that they should hear it, but not be alarmed that they think it came from 20 yards away!
I also grunt with my mouth when bowhunting or deer is close enough to hear it. Whatever I do, I try not to make the noise something that will alarm them to the point where they start to tense up. I want them to stop so they can investigate what they heard, not to get ready to run to the next county!
If I'm bowhunting on a trail that I suspect walking deer to come by that won't be stopping, the BEST thing I've done is to make a mock scrape. Make it very visible and applying lure or urine to it will help too. Matter of fact, having nothing in it will work as well because it's the visual part of them that works wonders. Whether they stop for the odor of the lure/urine or fresh dirt, they stop regardless. When using lure to stop them for a shot, don't add too much or it will alarm them. I've seen deer hit a scent stream, stop and run off a few yards!
As for the video Bass Pro hunter(LOL!), he's right(partially), but that depends on the scenario. You have to use common sense on when, how and how loud to make the sound. Experience will show you how. I use to mess with deer many many times while I was in my treestand. I use to make all sorts of noises to see their reaction. I experimented with metal sounds, mouth whistling, branch breaking, grunt calls and MOVEMENT! Yeah, movement. You'd be surprised to experiment by making a movement to get their attention, then as they stop to stare harder, you freeze like a statue. It'll teach you quick about camouflaging yourself, proper backdrop & covering along with the quantity and speed of your movements.
