A complete precision-measuring system for serious bow technicians

The Last Chance Universal Tuning Gauge (UTG) is engineered as an all-in-one tool for diagnosing, measuring, and tuning every critical aspect of a compound bow setup.
Designed for maximum accuracy, it measures string angles, verifies peep, nose, and kisser button positions, sets nock height and D-loops, and checks blade angle, center shot, cam lean, tiller, and static timing.
With laser-etched markings and dual adjustable pointers, the UTG provides consistent reference points whether the bow is at rest or at full draw.
Built for both pro shops and detail-focused archers, it streamlines tuning while delivering repeatable, professional-grade results.
