Carbon Express Pro Bow Square Bow Tuning Tool

The Carbon Express Pro Bow Square is an essential bow tuning tool for archers who want consistent, repeatable arrow flight from their setup. A bow square is what lets you set your nocking point, dial in the tiller, and verify brace height, three of the most critical variables for accurate shooting and a clean tune.

Built to work on both recurve and compound bows, the Pro Bow Square features metal clips that hold it firmly against the bowstring during setup so your measurements do not drift mid-tune. The integrated ruler carries both metric and standard markings and reads out to a full 12 inches, so you can set nocking point height, brace height, and tiller directly off the same reference without converting units.

Finished in Carbon Express' signature red, the square is ambidextrous and compact enough to live in your range bag or bow case. Whether you are building a new bow from the riser up or fine-tuning a long-trusted rig, the Pro Bow Square gives you the consistent reference points every tuning session depends on.
