Dual Shellfish Gauge – 140mm Crab & 88mm Lobster Measuring Tool (Pack of 2)

Fast, Accurate Field Compliance Checks with Multi-Buy Pack Value

Checking legal minimum landing sizes at sea or along rocky coastlines requires a fast, reliable tool. Metal gauges easily corrode, weigh down gear bags, or scratch equipment, while cheap molded plastics crack underfoot 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 140mm and 88mm marine measuring gauge is engineered for rapid size verification. Featuring precision openings for 140mm crab and 88mm lobster legal limits, this tool gives recreational and commercial fishers an instant compliance check right at the water's edge. Supplied in a discounted 2-pack, you can keep one on the boat or shore bag and a spare in your tackle box.

Key Marine Engineering Features & Field Benefits

• Dual 140mm & 88mm Precision Slots: Features a 140mm slot for crab width checks and an 88mm slot for lobster carapace checks—covering two essential compliance measurements on a single compact tool.

• Discounted 2-Pack Value: Standard production is optimized to print two units simultaneously, allowing us to pass significant manufacturing savings directly to you.

• 100% Weatherproof Marine PETG: 3D-printed using high-density, marine-grade PETG polymer. It will not absorb saltwater, degrade in direct UV light, or snap when dropped on wet rocks or boat decks.

• High-Visibility Contrast Markings: Printed in high-visibility yellow with bold red digits, making size dimensions clear and readable in direct sunlight, low light, or through heavy sea spray.

• Fully Custom Sizes & Combinations: Need specific regional slot sizes (e.g., 150mm, 160mm, or custom Ormer/Abalone dimensions)? Gauges can be custom-modeled and printed to your exact millimeter specifications.
