The unique line biter is designed to be attached to your main line between the rod tip and the water and will exaggerate any tiny indication, ensuring that you don’t miss a thing.
They attach to the line via a clip, the same as a back lead does, they’re hi-viz with glow-in-the-dark tape around the neck so you can keep an eye on what’s occurring even at night.
They are also invaluable for giving you a visual indication of where your lines are when returning to your swim in a boat, allowing you to easily see and avoid your main lines and avoid any potential disasters.
