If you're into crabbing or lobster fishing along the East Coast, this measuring gauge is an absolute must-have to stay legal and avoid those expensive citations. This thing has all the common measurements you need pre-cut right into the thick plastic - from 4.5 inches all the way up to 6.5 inches for various crab species, plus updated Florida Stone Crab and Spiny Lobster gauges at 2-7/8 inches and 3 inches. There's even an 8-inch ruler on top for quick measurements. It's built tough to handle the harsh marine environment season after season without warping or breaking down. The design makes it easy to carry around - you can hang it from your gear or toss it in your bucket without worrying about damage. It covers blue crabs, stone crabs, peeler crabs, lobsters, and more, making it the only measuring tool you'll need for your fishing adventures. Made in Taiwan with that quality craftsmanship, it's one of those simple tools that just works perfectly every time you need it.
