Gabriel "Gaby" Ferdocampo is a member of Pena tiro Gomero Castrillón. The broad finger-supported slingshots are used by several shooters of the club. Note the well thought-out attachment method: The rubber is attached to the lower part of the metal hook and then runs over the upper section, thus resulting in a shoot-over-designs with relatively unobstructed field of view. The upbent part of the right hook is used to aim.
Thanks, Gaby!
