This essential piece of lobstering gear can easily be attached to your tickle stick and is used to measure the carapace of your Florida spiny lobsters in the water. The Scuba Choice mission is to provide beginners and experienced divers worldwide with an informative, convenient, and reliable one-stop shopping environment where they can buy extensive water sports equipment ranging from personal snorkeling gears to advanced scuba gear at unbeatable prices. Spiny Lobster must have a minimum carapace length of greater than 3-inches and the measurement must take place in the water. The carapace is measured beginning at the forward edge between the rostral horns, excluding any soft tissue, and proceeding along the middle to the rear edge of the carapace.
