Shellfish Gauge – Ormer & Abalone Ergonomic Sizing Tool (Double-Sided 90mm / 9cm)

Fast, Accurate Field Compliance Checks for Channel Islands & Coastal Gathering

Gathering ormers (Haliotis tuberculata) and abalone along rocky intertidal zones or while diving requires a tool that is easy to grip with cold, wet hands or thick neoprene gloves. Standard flat measuring plates are awkward to handle in shallow surf, while metal gauges can corrode or scratch delicate equipment.

Designed and manufactured in the UK by an engineer with over 30 years of precision CAD and tooling experience, this double-sided 90mm ormer and abalone gauge features an integrated ergonomic handle for fast, secure handling. Precision-engineered with an exact 90mm (9cm) measuring aperture and dual-sided high-contrast markings, it allows shore gatherers, free divers, and commercial fishers to verify legal landing sizes instantly in any orientation.

Key Marine Engineering Features & Field Benefits

• Precision 90mm (9cm) Measuring Aperture: Engineered specifically for 90mm minimum conservation reference sizes (MCRS) across Jersey, Guernsey, and regional coastal bylaws.

• Ergonomic Hand Grip: Built with an extended, contour-molded handle that provides a firm, slip-resistant hold even when wearing thick dive gloves or handling catch in cold sea spray.

• Flush Markings: Size dimensions are molded into one side of the gauge body, allowing instant size verification.

• 100% Weatherproof Marine PETG: 3D-printed using high-density marine-grade PETG polymer. It will not absorb saltwater, degrade under direct UV exposure, or fracture when dropped on wet granite rocks.

• Bespoke Regional Sizing: Need a custom aperture for alternative regional bylaws (e.g., Guernsey 80mm ormer, custom UK mainland, or international abalone sizes)? As the original designer, master CAD models can be modified swiftly prior to dispatch.
