Aluminum mold milled with CNC machine, complete with a recess for a long tail 2mm in diameter. This shape with long tail has been used by our champion Lorenzo Secchiaroli in the World Championship of Port D'Albret, combined with a 018 coil was the winning with the ocean waves.
The long tail favorice sediment exclusion in soft or muddy bottoms and being able to use a thinner wire coil around the suction system is less influenced by the currents.Staying in horizontal is easy to decide the length of the long tail, putting it more or menno the mold. Solution also useful for the construction of mini beams.
