The innovative Roisub Shark System provides a stand-off block for reel mounting, for mounting line guides and also provides double loading hook fins for dual rubber set-ups.

It is the ideal solution for multi-elastic spearguns, like the Roisub Generation III (Fusion & Demo), because it allows a fast and accurate coupling / uncoupling of the pairs of rubber on the sides of the speargun, freeing up the bottom of the speargun

This set-up allows the action of loading, without having to even look.

Designed to fit round barrels up to a maximum outside diameter of 31mm.
