LOL! I know the quieter I try to be, the noiser I end up being. Usually it's a good loud clank, like my metal harness carabiner hitting my climber as I bend over to set it up. Or the top of the climber will fall down and hit the bottom as I mess with the one or the other.
I've kind of given up trying to be quiet. Where I hunt we can't use bright eyes or other markers and my GPS is only good to about 60 ft so I spend a lot of time stomping around in the brush and briars looking for a tree to climb... then I set up and climb. Loudly.
When I feel like being extra noisy, I'll set up my camera arm. There's just no quiet way to crank on a ratchet strap as far as I can tell.
(I try... but it's sort of an effort in futility)
