While underway the bow of your powerboat tends to ride at an elevated angle, causing your radar to be angled. With Edson's 67550 0-4 degree Wedge for Round Base Vision Mounts the elevated bow will be offset aligning your radar to see better. Edson's 0-4 Degree Wedge requires an Edson Mounting Plate and an Edson Vision Series Mount. Order Base Mount and Mounting Plate separately.
