The body of the Speedhook is made of cutlery grade stainless steel that is stress relieved and heat treated. This type of metal has memory to it so that it can bend into the set position every time it set. The tension on the Speedhook can be adjusted. So, whether you are fishing in rushing waters or ice fishing, the Speedhook can adapt to any water condition. Features: SETS FISH HOOK AUTOMATICALLY: The Speedhook is designed with spring loaded pressure, when set, to catch a fish. The slightest bit of pressure will trigger the device, causing the hook to set, automatically, within a fraction of a second. PERFECT FOR CATCH AND RELEASE FISHING: The Speedhook sets the hook so quickly that there is no time for the fish to swallow the hook. Therefore, the Speedhook will always hook the fish?s mouth, creating the perfect device for catch and release fishing. NO FISHING POLE REQUIRED: The Speedhook can be used with or without a fishing pole when a throw line is attached. It can even be cast when the tension is adjusted accordingly. EXPONENTIALLY INCREASES CATCH SUCCESS RATES: The Speedhook triggers with such velocity that it will produce a higher catch success rate and yield. It will turn nibbles into hits. ADJUSTABLE TENSION: The Speedhook comes with a tool to adjust the tension. Move the latch inward on the days when you?re fishing in rushing waters or casting short to moderate distances, and outward when fishing for small fish or ice fishing. ESSENTIAL FOR SURVIVAL KITS AND BUG OUT BAGS: With a Speedhook, you can set it and forget it with a throw line or a pole. This device can do the fishing for you while you spend your time and resources on other priorities. STAINLESS STEEL CONSTRUCTION (WIRE FORM): The body, or wire form, is made with stress relieved and heat-treated stainless steel, making it extremely durable. The Speedhook can be set over and over again while always returning back to its original shape. 100% MADE IN THE U.S.A.: All of the components of the Speedhook are acquired from U.S. based companies and the Speedhook is fully and proudly assembled in the United States.
