  - A great new design that protects your investment! Inside padded with denim outer, they keep the control box from getting beat up every time you set your detector down to dig a target.  A great fit with velcro straps to keep it snug. Four colors available including Black.
NOTE:  The cover straps have been changed from 2" inch wide to 1" wide to clear the controls and switches better.
