Florida Spiny Lobster Gauge – 3" Legal Carapace Measuring Tool

Stay compliant on the water and protect your harvest with our premium Florida spiny lobster gauge. Precision CNC-machined in the USA to the exact 3-inch carapace minimum size required by Florida FWC regulations, this heavy-duty gauge is built to withstand years of demanding saltwater abuse without bending, cracking, or corroding.

Crafted from ultra-rigid, UV-stabilized King ColorCore (StarBoard) HDPE, this gauge serves as the ultimate rust-free, floatable alternative to flimsy metal gauges that scratch your boat's gelcoat or sink to the bottom if dropped. Featuring a high-contrast dual-layer design, it allows you to instantly verify a legal catch in seconds—whether you are diving the clear waters of the Keys or sorting your catch on deck.
