I kill the majority of my deer from the ground with a bow while still hunting or stalking. I always hear guys say "when you think you're going too slow, slow down". I kind of disagree with this. I tend to move as fast as I think I can get away with. This is obviously easier said than done and takes a TON of trial and error to figure out. Its taken me bumping literally thousands of deer and attempting stalks on hundreds just to get kinda good at it. You have to learn when to move slow, when to be still, and when to move FAST. This is a critical part that I don't hear talked about much. The buck in my avatar is a good example. I spotted him moving through a bedding area about 75 yards away. He dropped into a small ravine and as soon as he was out of sight I sprinted 50 yards to cut him off. Not 10 seconds after I got in position he popped back up out of the ravine 30 yards from me... Night night. This is just one example. I find myself fast walking, running, speed crawling etc. during stalks all the time. I would venture to say I spend a lot more time sitting still, or moving fairly quickly from cover to cover once I know the coast is clear than I do actually moving slowly. Like
@Recurveaholic said, it's absolutely critical to see the deer before they see you. Binoculars are mandatory for this kind of hunting. When attempting a stalk, if you lose sight of the deer, DO NOT lose confidence and let your gaurd down. He likely didn't go far. I can't tell you how many times I've lost sight of one on a stalk, got impatient and let my guard down only to bump the buck from right where I KNEW he was. Also when you do bump the buck you're stalking (and you will) don't give up. Most guys think if you bump him it's game over. When I bump one it's game on. I've had good luck catching back up with them the same day after a light bump. Again they usually don't go far. That seems to be a common theme with a lot of the older bucks on the pressured public I hunt. They don't go far.
