The original award-winning Bluefin Tuna Ruler by Release Ruler is designed for anglers targeting giant bluefin. Measuring 2″ x 125″, this durable ruler allows you to quickly measure your tuna boatside for length verification and tournament compliance.

Made from dimensionally stable, flexible PVC vinyl, the ruler is tear-resistant, non-corrosive, and built to withstand offshore conditions. It rolls up easily for storage and provides true-to-scale measurements up to 125 inches.

A unique feature of the Bluefin Ruler is its patented weight estimation scale based on established bluefin growth data. The high-contrast, vivid graphics make measurements easy to read while providing an approximate weight reference for catch documentation and release situations.
