Double-Sided Ormer & Abalone Shellfish Gauge (80mm & 90mm)

Fast, Ergonomic Dual-Size Compliance Checks for Shellfish Harvesting

Having to carry multiple single-size measuring tools while wading, shore gathering, or diving creates unnecessary clutter in your kit. Fumbling with separate rulers in cold coastal waters or while wearing heavy gloves slows down your catch checks and risks dropping gear into deep rock pools.

Designed and manufactured in the UK by an engineer with over 30 years of precision CAD and tooling experience, this double-sided dual 80mm and 90mm shellfish gauge provides two essential size checks in a single, lightweight tool. Built with a contoured central handle and high-visibility permanent size markings, it allows you to test both 80mm and 90mm legal limits instantly.

Key Marine Engineering Features & Field Benefits

• Dual-Size Combination (80mm & 90mm): Features an 80mm opening on one end and a 90mm opening on the opposite end—allowing you to quickly check different species or regional landing limits without swapping tools.

• Ergonomic Center Handle: Designed with a contoured paddle grip that provides maximum control and leverage, even when working with wet hands or thick neoprene dive gloves.

• Clear Molded-In Size Markings: Millimeter dimensions are permanently 3D-molded directly into the body of the gauge, ensuring the text will never rub off, fade, or peel in marine environments.

• 100% Weatherproof Marine PETG: Precision 3D-printed using heavy-duty marine-grade PETG polymer. It will not absorb saltwater, degrade under UV exposure, or fracture if dropped on wet rocks or boat decks.

• Custom Regional Sizing Available: Need a different combination of sizes to match your local district bylaws (e.g., 80mm / 87mm, or 85mm / 90mm)? The CAD file can be altered to your exact millimeter specifications prior to dispatch.
