Bow Master press has a 6in jackscrew which has two benefits.

The second benefit is that it allows for the complete tear down of bows with high pre- loaded limbs. The Bow Master Portable Bow Press puts all the capabilities of a full size bow press in the palm of your hand. The Bow Medic is small enough to fit easily into your pack or even your pocket, making it a truly portable bow press. The Bow Maser portable bow press allows the pro shop or archer to easily replace the string or cables, install peep sights, adjust draw length, replace wheels or cams or replace the limbs.
