The Airfly aluminum crab and lobster gauge has two laser-etched slots - 5" for Blue crab carapace width and 3-1/4" for American lobster and California Spiny Lobster. Both measurements are etched directly into corrosion-resistant aluminum, not printed or painted, so they stay readable after full seasons of saltwater, UV exposure, and gear impact. The 5" slot covers hard male Blue crab across Maryland, Virginia, Louisiana, North Carolina, South Carolina, Georgia, Florida, Texas and Alabama. The 3-1/4" slot covers American lobster in Maine, New Hampshire, Rhode Island, Connecticut and Canadian Maritime Provinces, and California Spiny Lobster from San Diego to Point Conception. Same slot, both coasts, no switching tools. Slim enough for a wader pocket, bib apron, life vest, or dive bag. The lanyard hole keeps it clipped to a trap harness, dive kit, or gear bag for one-handed access mid-haul or underwater. Works for recreational pier crabbers on the Chesapeake, lobstermen running pots in the Gulf of Maine, and California Spiny Lobster divers who need a fast carapace check before surfacing. Pairs with Airfly crab traps, 4-arm stainless harness, and throw line kits. Designed in San Francisco - patent pending with USPTO.
