String aid works best on EXCALIBER. If your is compound, a bow press; or, the mecahnical cocking device can be made to work. Just make a couple of loops from strong thin rope, attach then to the limb ends then connect the hooks of the mechanical cocker to the loops. Take up enough slack to remove the bowstring, etc. You could do the same with a string cocker but would need someone to remove the bowstring while you hold the string cocker tight.
