Exactly, it does give them a false sense of security. One more tip though. The deer only feel safe with you coming in on a loud machine. You still have to stalk in unseen to get a shot.

One very cold and long winter when the deer were starving, I used to stop on my way out with a hitch of logs and try to feed deer with apples from an orchard. If I turned the machine off and walked towards the apple trees, they would run even though they were hungry. But if I left it running they would allow me to approach and shake apples off the trees for them.

You still have to stalk in. I used to sometimes walk in with a chainsaw to cut at daybreak and the deer would run, they are only used to the loggers coming in with machinery, and any alteration will spook them.
