The Blade 4 Dual Core dartboard reaffirms Winmau’s pioneering role in the field of dartboard innovation taking our values of design, craftsmanship and engineering excellence to another level. The Dual Core technology achieves lower compression at the outer core which reduces surface resistance and increases point penetration for fewer lost darts and higher scores. Higher compression at the inner core increases resistance below the surface, absorbing excess kinetic energy for improved durability. The pure sisal outer core has an uncompromised playing surface for perfect vision, increased scoring potential and easier alignment. The Rota-Lock system featured in this dartboard utilises triple wheel locators to allow the dartboard to be fitted to virtually any surface in a matter of minutes for a secure fit and easy rotation.
