    Description

    • Seahorse SE331 Protective Case – Built for Adventure, Designed for Life

      Protect your gear wherever life takes you with the Seahorse SE331. Designed as a rugged upgrade to the popular SE300 series, the SE331 features Seahorse’s innovative TwistLock latches for secure, reliable closure. Constructed from tough polypropylene and engineered for precision, this compact case offers unbeatable protection for electronics, tools, firearms, first aid kits, and more.

      Waterproof, Crushproof, and Dustproof Reliability
      The SE331 stands up to the toughest conditions. Certified IP67 waterproof, dustproof, and impact-resistant, it’s built to protect your valuables during boating, yachting, travel, field work, or emergency situations. A Seahorse case ensures your equipment stays dry, clean, and fully protected against the elements.

      Flip Latch Pressure Equalization System
      Integrated into the TwistLock latches, Seahorse’s Flip Latch Pressure Equalization System automatically balances internal pressure for effortless opening, even after air travel or high-altitude exposure. A molded comfort-grip handle makes carrying easy, whether you’re heading to the marina, the mountains, or beyond.

      Travel-Ready and TSA-Friendly
      Meeting TSA requirements and rated ATA-300 for rugged transport, the SE331 offers secure travel protection. Three built-in padlock eyelets allow you to add TSA-approved locks, and metal keyed lock upgrades are available for enhanced security.

      Interior Options for Maximum Protection
      Choose the SE331 with either a standard empty interior or upgrade to AccuformFoam—a customizable, low-density foam insert that safely cradles electronics, cameras, pistols, tools, and specialty equipment. Create a snug, custom fit to match your gear’s exact shape.

      Versatile Protection for Every Mission
      From smartphones and GoPros to compact drones, test meters, pistols, ammo, or emergency supplies, the SE331 is a favorite for outdoor enthusiasts, tactical operators, medical teams, and recreational boaters. It's also perfect as a dry box, first aid kit case, or general utility storage solution.

      Made in the USA – Lifetime Guarantee
      Every Seahorse case is proudly manufactured in the United States and backed by a lifetime warranty against manufacturing defects. Built for performance. Built for life.
