Under the Arrow BUBBLE

Developed by Pat Norris for BareBow and String Walking Archers.  Pat's new under the arrow Level bubble fits directly on the PNA X-Factor compound bow.  The bottom hole is round and the top hole is slotted so that you can adjust the bubble to dead center.

This bubble can be added to both recurve and compound bows new and older models by just drilling and taping two holes.  It comes with two mounting screws and the level installed in the aluminum bracket.  Level is 1 1/4 inches long.
