There are a lot of tools out there designed for use on a boat when you're having a bad day on the water. But what about a good day? Headhunter Spearfishing created the perfect multi-tool for a great day on the water. It features a 3” lobster gauge and a 2.75” stone crab claw gauge. And after you have your legal limit you can use the most important tool a boat can ever have, a bottle opener. Made of stainless steel, this tool is built to survive a life in or above the water.
