Heavy-Duty Shellfish Gauge – Dual 150mm Crab & 87mm Lobster Tool

Fast, Accurate Field Compliance Checks for Coastal Anglers & Commercial Crews

Taking the guesswork out of minimum landing sizes on a wet deck or along rocky shorelines requires a reliable, highly visible tool. Metal gauges can corrode or add unnecessary weight to gear bags, while low-grade plastic gauges easily crack under foot or warp in direct sun.

Designed and manufactured in the UK by an engineer with over 30 years of precision CAD and tooling experience, this heavy-duty 150mm crab and 87mm lobster gauge delivers rapid, accurate size verification. Featuring dual precision cutouts tailored to standard 150mm crab and 87mm lobster legal limits, it gives both recreational anglers and commercial fishers an essential compliance tool right at the water's edge.

Key Marine Engineering Features & Field Benefits

• Dual Precision Cutouts: Features an 87mm slot for lobster carapace checks and a 150mm slot for crab width checks—giving you two vital compliance checks on a single compact frame.

• 100% Weatherproof Marine PETG: 3D-printed using high-density, marine-grade PETG polymer. Extremely tough, flexible, and completely weather-resistant, it won't absorb saltwater, degrade under UV rays, or snap on boat decks.

• High-Visibility Contrast Finishing: Supplied as standard in high-vis yellow with bold red digits, making size dimensions instantly clear in direct sunlight, low light, or through heavy sea spray so you won't lose it on shore or onboard.

• Lightweight & Field-Portable: Compact design fits easily into a tackle box, pocket, fishing vest, or gear bag without adding unnecessary weight.

• Bespoke CAD Sizes & Custom Colors: Need specific regional slot sizes (e.g., 140mm, 160mm, or custom Scallop/Ormer dimensions)? Gauges can be custom-modeled and printed to your exact local regulation specs or preferred color schemes.
