🦀 5-in-1 Precision Gauge: The first durable aluminum tool to support 5 distinct measurements (3", 3-1/4", 4", 5", 5-3/4"). Accurately measures Dungeness, Blue, & Rock Crab plus Lobster to ensure legal compliance every time. 

💎 Heavy-Duty Aluminum: Crafted from premium, corrosion-resistant aluminum. Unlike plastic competitors that crack or fade, this rust-proof gauge withstands harsh saltwater environments season after season.

🌎 Universal Regional Support: One tool for all waters. Covers regulations for California, Canada, New England (ME, MA, RI, CT), and the Atlantic/Gulf Coast (FL, MD, VA, TX, LA, NC, SC, GA, AL).

🎣 Compact & Portable: Slim, lightweight profile fits perfectly in any tackle box, pocket, or gear bag. The essential "carry-anywhere" accessory for recreational and commercial harvesters.

✅ Patent Pending Design: Uniquely engineered in the USA to replace multiple gauges. Features clear, permanent markings for quick carapace checks, preventing fines and protecting marine life.
