Northern Ireland-Spec Shellfish Gauge – Lobster, Velvet Crab, Brown Crab, Spider Crab & Scallop Tool

Heavy-Duty Ergonomic Field Tool Engineered for NI Coastal Bylaws & Boat Decks

Navigating Northern Ireland (NI) fishery regulations without a rugged, accurate measuring tool puts sea anglers, potters, and commercial crews at risk of severe regulatory fines. Standard thin gauges flex under pressure, while prints with raised lettering catch on nets, scratch cold hands, and collect dirt.

Designed and manufactured in the UK by the original CAD designer, this Northern Ireland-spec multi-species shellfish gauge is engineered for brutal marine conditions. Built with a heavy-duty 90% ultra-dense infill and completely smooth, flush-integrated lettering, it provides instant legal size verification across five target species without flexing, cracking, or snagging gear.

Key Marine Engineering Features & Field Benefits
