Technical sets from Tecline and Apeks: SemiTec, sidemount and DIR regulator sets on the R2, R4, R5 and V1 Ice first stages, the Apeks VX mask and RK3 fin sets, and the Apeks backmount twin BC system. Each set is built around one configuration, so check hose lengths and port layout against the cylinder setup it will run on before ordering. Single regulators are in regulators.
