Hydrolastic is the award winning revolutionary concept in pole elastic. It offers a multi phase performance delivering a wide scale of ratings within one set up which is perfect for mixed fisheries and high catch rate venues. Hook a big fish and Hydrolastic will increase to a higher rating as it is loaded with more `give` than standard heavy elastics. Unlike other types Hydrolastic has a hollow construction, which is filled with a secret high performance fluid and is a fully patented design. The elastic stretches first, then, when compressed, the internal walls close in and are held apart by the fluid. All colours are supplied in 3m lengths. Now in 3 – 5 Yellow, specially for Silvers! Now in 4 – 8 Orange, specially for F1’s!
