I use the Nikon Retractable Rangefinder Tether and it works excellent. I clip the tether to the shoulder strap on my pack, to the very top of my shoulder. (If there isn't a loop to clip to on my shoulder strap I put one there) That way the rangefinder settles between the ball of my shoulder and where my pectoral muscle starts. I'm right handed so i have it on my right shoulder. The amount of movement to bring the rangefinder from the right clavicle to my eye is very minimal, which I find extremely important when bowhunting. This is where the retractable part is nice too. If you let go to clip on, it sucks right back in out of the way instead of dropping or swinging on a cord.
The binocular harnesses with a pouch probably do a fantastic job of carrying a rangefinder. My setup is more geared for those moment of truth times when there is a bull at 40 yards and I don't want to have to find a pocket to get the rangefinder out of, or back into.
Also, the rangefinder rides well too. It doesn't swing around or get in the way if positioned properly.
