Before I place an arrow on the string I let my arm go slack an let the bow hang loosely off the sling for a second.
My sling is a small dog collar that is not connected to the bow,it just wraps around the riser.
All I do then is bounce the bow into my hand an lightly close it.
That puts the bow in exactly the same place every time.
If I then come to full draw and I haven't got it right, I instantly know by how the bow sits in my now open hand.
Get it wrong,,,,,,let down and reset.
Funny thing is that people that see me do this every time think I'm checking my feet as I look down, because I can't feel them properly due to nerve damage in my back and I've told people I'm checking my foot position every time, which I do at the same time.
