The iOptron CEM40/GEM45 LiteRoc tripod has a die-cast aluminum top with heavy duty stainless steel tripod legs. The new LiteRoc tripod features a 1.75” upper leg section with a 1.5” diameter lower section (same as the old 2” tripod), resulting in a lighter tripod with stability similar to the old 2”. It also has improved leg cuffs and sockets for further rigidity and redesigned leg lock levers securing the extensions position.
