Vent-Rite is a handy little tool that allows for the easy and efficient ‘venting’ of over inflated swim bladders when releasing fish caught from deeper water.Venting the swim bladder, when done properly, allows the fish to swim back down and return to its bottom habitat.This venting tool is lightweight and has an easy-to-use pushbutton unlock and an automatic locking feature for safety of the spring loaded retraction and extension of the protective needle sheath. The needle and inner spring are made of high quality stainless steel.
