Do you, or should you, use one?
Ask two different archers and you will get two different answers. The reality is that everyone should be using a bow sling, whether it be a thumb/finger type or the standard wrist type.
A properly installed and adjusted bow sling gives the shooter the confidence to relax the bow-hand during the shot sequence. Using a bow sling should (and will) eliminate the fear of the bow jumping right out of the hand at the shot.
The bow sling will also greatly reduce bow hand torque by allowing the shooter to totally relax the bow hand while executing the shot sequence.
I can speak from personal experience.. ......my bow (at that time) had no sling on it because it had worn out and I hadn't replaced it. I didn't think I really needed one, if truth be told.
I was at the practice range one sloppy, wet December day. It had been raining for most of the week and had just tapered off that morning, so off I went to get in some fine tuning.
I was standing in about 2" of mud, water and grass - no big deal really as I had my "Wellies" on - and it wasn't too cold. Well after a half hour or so
shooting and minor adjustments I was working on my 20 yard groups when I drew back, settled in to my anchor, and was concentrating on the spot when the release did its thing - totally unexpected.
Since I shoot with a very soft grip - almost no grip at all - the release of the arrow caught me off guard and the bow jumped right out of my hand. It went about three feet forward and straight down into the muck, water, grass, dirt and crappy-poopa that I was standing in.
The sight, string, cable, cam, idler wheel, and just about r=everything else was covered on the said crappy-poopa. I did te only thing that I could think of at the time by getting my water bottle out and dousing the affected parts to try to get the majority of the mud off before it dried.
Nothing worse than having dirt granules in the grooves of the cam and idler wheel.
Anyway, the point is that had i put on another bow sling the above accident would not have taken place. At all.
I had always thought that it would never happen to me. Quite an eye opener. So.....moral of the story? Get, and use, a bow sling - it'll do nothing but good for you.
