Take your bow tuning to a new level of precision. Fine-tune on 2 axes at the same time without moving your bow.
Use with either vise style. 
Includes 1 microadjuster, extension plate and all hardware. 
 
NOTE: this kit is an expansion for use with your existing microadjuster.  If you have a Ball Mount Vise with NO microadjuster, you will need to order a second microadjuster.
