Shellfish Measuring Gauge – Dual Crab (150mm) & Lobster (88mm) Gauge

Fast, Accurate, & Field-Tested Size Compliance for Coastal Fishing

Using flimsy or inaccurate measuring tools on the water risks compliance fines and wasted time. Standard plastic tools can warp or snap under marine conditions, while metal gauges rust and add unnecessary weight to your kit.

Designed and manufactured in the UK by an engineer with over 30 years of precision CAD and tooling experience, this heavy-duty dual shellfish measuring gauge gives recreational anglers and commercial fishers an instant, accurate size check. Precision-engineered with standard 150mm crab and 88mm lobster gauge openings, this tool delivers fast, legal compliance checks right at the water's edge or on deck.

Key Performance & Marine Engineering Features

• Dual Precision Openings: Features exact 150mm (Carapace width for crabs) and 88mm (Carapace length for lobsters) slots for quick, mistake-free measurements.

• 100% Saltwater & Weatherproof PETG: 3D-printed using high-density marine-grade PETG polymer. Unlike PLA or cheap plastics, PETG will not absorb water, warp in hot sun, or degrade in saltwater environments.

• High-Contrast Lettering: Molded with high-visibility red numerals against a bright yellow background, making sizes easy to read in low light, spray, or harsh glare.

• Ultra-Durable & Lightweight: Designed with structural wall density to survive being dropped on rocks, tossed into tackle boxes, or stored in marine environments without cracking.

• Custom Sizing Available: Need custom regional minimum legal sizes (e.g., 140mm, 87mm, 110mm) or specific combinations for local fishery bylaws? Custom gauge configurations can be produced to order at no extra charge!
