Retro fitting any Gdivers, Raptor, or Space mask from 2006 on, the Extender kit is here to extend your diving possibilities. The Kit includes various accessories that integrate with communication units, but it also is compatible with sport camera mounts and can customized endlessly. The Kit comes in multiple colors, with the new NACS and earphone supports. The Space Extender is ready to extend your scuba activities to whatever you want: not only can you communicate with your buddies during the dive, thanks to the MHA2 support and the new improved NACS (communication unit not included), but it's also equipped to mount up to 3 sport cameras. Frame and components are made from durable impact resistant plastic with corrosion resistant hardware. Kit is easy to install.
