This is a Florida Lobster measuring device. According to the Law (FWC, Florida Wildlife Commision): possession and use of a measuring device is required at all times when catching spiny lobster. The Carapace (head of the lobster) must be larger than 3", and measured in the water. This device is made of aluminum and is laser cut, so it has an ultra precise measurement!
The rope fits perfectly in our Lobster Net and Tickle Stick handles!
