i got my drawloc unit to add to my Hoyt bow after a elbow operation a few years back in the fall of 06 at the end of the season i got what they call scar tissue to the point where i cannot hold my reg bow back more than few seconds . then i started watching hickory creek on the mens chann after calling and talking to them and i was given the local dealer who installed and laser tune it in the summer of 07 and i was ready.
