Designed for Consistent Performance

The Sigma is engineered for archers who want more control over how their release feels and performs. Its ergonomic handle helps establish a repeatable hand position, while adjustable trigger and travel settings let you tailor the release to your shooting preferences. The result is a refined thumb-button release designed around comfort, control, and consistency.

Care and Use

Use the release according to Scott Archery's instructions and inspect it regularly before shooting. Scott Archery recommends blowing the release out with dry air after use in damp conditions and lightly lubricating it with a light machine oil once dry. The release may be used with a bowstring loop or directly from the bowstring when used with an appropriate eliminator button or synthetic nocking point. Scott Archery specifically cautions against using its releases with metal loop devices or allowing the release jaws to contact a metal nock set, as this can damage the release.

Always use safe archery practices, including never drawing a bow without an arrow and never pointing a drawn bow in an unsafe direction.

Warranty

Scott Archery backs its releases with a limited lifetime warranty. Warranty service is subject to Scott Archery's inspection and approval. An RMA must be obtained before sending a product in for warranty service.
