Dive Gear That Keeps What You Catch

Keystone Dive Products Inc.™  is the patent holder and manufacturer of the Original Lobster Inn™ — a unique catch bag trusted by divers nationwide. Our patented one-way flap lets you store your catch with confidence. Once it’s in the bag, it’s not coming out until you want it to. Bottom zipper allows the extraction of your catch.


We serve novice and expert divers across the U.S. with heavy-duty, easy-to-use catch bags for lobster, crab, lionfish, and more. Designed and manufactured in Palm City, Florida, and built for the realities of underwater hunting, our products are relied on by warm oceanic water divers.


Our mission is simple: to make your catch more secure, your gear more reliable, and your dive experience more successful.

What Makes Our Products Unique

Not all catch bags are built the same. Here's what sets Keystone Dive Products apart:

  • Patented Flap

    The Original Lobster Inn features a no-fail flap that lets catch in, but not out. No struggling with zippers or worrying about a lost catch.

  • Rugged Build Quality

    Made for reefs, wrecks, and repeated dives. Our mesh is tear-resistant and reinforced to withstand tough environments.

  • Purpose-Built Bags

    We don't sell generic gear. Each product is designed for specific underwater catch—whether it’s a spiny lobster, soft-shell crab, or sharp-spined lionfish.

  • Field-Tested Performance

    Every product is designed and tested in the waters of Florida, ensuring it performs under real diving conditions.

  • Direct-to-Diver Sales

    Buy straight from us. Get better prices and better service.
