The Mares Power Plana (XR Line) is the brand's rubber fin built first and foremost for extended-range and technical diving. Moulded from high-quality natural rubber with reinforced ribbing, it is heavy, solid and effectively indestructible, which is exactly what technical divers want underfoot.

The ribbed blade loads water efficiently while drain channels let trapped water escape. That combination delivers strong propulsion across every kick style and excels at the frog kick that technical and overhead-environment divers rely on for precise, low-silt movement.

The dense rubber gives the fin negative buoyancy, which helps with trim, and a spring strap handles the demands of cold-water and dry-suit diving. For Indian divers moving into technical training, the Power Plana is a serious, long-lasting tool.
