Channel Islands Ormer & Lobster Gauge – Dual 87mm Marine Measuring Tool

Dual 87mm Compliance Checks for Guernsey & Channel Islands Waters

Measuring marine catches accurately at sea or along the rocky coastline requires robust, saltwater-proof tools. Traditional metal gauges can corrode or add weight to your dive kit, while cheap molded plastics easily crack on rocks or warp in direct sunlight.

Designed and manufactured in the UK by an engineer with over 30 years of precision CAD and tooling experience, this dual 87mm marine gauge is specifically configured for recreational divers, commercial fishers, and shore gatherers across Guernsey and the Channel Islands. Precision-engineered with two standard 87mm slots (for Ormers and legal-size Lobsters), this tool delivers fast, legal compliance checks right at the water's edge.

Key Marine Engineering Features & Field Benefits

• Dual 87mm Precision Openings: Features two identical 87mm precision slots for fast, dual-check measurements of Ormers (Haliotis tuberculata) and minimum legal size lobsters without adjusting your grip.

• Dual Lanyard Mounting Holes: Molded with two heavy-duty attachment points so you can easily secure the gauge to a wrist lanyard, dive harness, belt clip, or catch bag—ensuring it won't drift away in coastal currents.

• 100% Saltwater & Weatherproof PETG: 3D-printed using high-density marine-grade PETG polymer. Unlike PLA or low-grade plastics, PETG will not absorb water, degrade in UV light, or snap when subjected to impact.

• High-Visibility Engraved Digits: High-contrast red lettering set against a bright yellow background makes measurements easily readable underwater, in low light, or through sea spray.

• Custom Gauge Sizes Available: Need specific regional combinations (e.g., 87mm Ormer / 140mm Crab, or custom UK mainland dimensions)? Gauges can be custom-modeled and printed to your exact millimeter specifications.
