When I bought my Darton bow I got hop when I shot, in other words the bow comes up after the arrow clears the bow. I put on a stableizer that I could add weight too if I needed it. The stableizer was a 3/8ths shaft 12″ long and the weight on the front had a hole drilled and tapped to receive more weight if the shooter wanted more. After shooting with the weight that came with it I was still getting hop and put on another 3 oz.s and that cured it. The bow I had was a top of the line darton and it was a nice, fast bow and when I added the stableizer and extra weight it solved the problem. On the 20 yrd course I was shooting on it pulled my arrows together more consistantly. Once in awhile when your shooting targets you’ll occasionally (drop and arrow) slightly and the stableizer helped alot solveing this problem. Dropping an arrow was when you shoot 5 arrows and 4 hit well, the other one dropped out of the center ring around the bullseye.
When your shooting more then 75 arrows in a 3 hour shoot and really trying to hone where you want an arrow to hit your arm gets fatigued and your shooting falls off, useing a stableizer really helps this and you can also decide which way to reset your sights if you have too. It calmed my patterns down and I then was able to decide what my arrows were doing. If I dropped an arrow I knew why and what I was doing wrong then I could adjust my grip, stop torqueing the riser or just plain telling myself to concentrate more, calm down and let my breath out. Shooting targets with a bow is a science just like shooting targets with a rifle. With a stableizer you can really pull your groups together, without one and its just shooting into the wind, thats why archers that shoot targets in competition always use a stableizer. When you finially get your bow tuned in too your way of shooting you can drive nails with them.
