The Mares Cyrano Evo HF Pneumatic Spearguns use a 11mm. diameter internal barrel with sliding piston, making it easy to load and allowing the shaft to propel at high speed with superior power and accuracy. These spearguns are designed with an ergonomic handle with high-function grip and concave thumb surface. They have an adjustable distance between trigger and handle to accommodate personal ergonomics. The outer barrel has a circular section 40mm. in diameter, a light single-piece head, small cone with steel cord sheath and side line sheath pin. The lubrication and decreased friction in the piston increases speed and ease of loading. A 7mm. threaded shaft tip is included.Key Features:Color: Black with orange accentInternal barrel off axis to ensure naturally instinctive aimOuter barrel 40mm. dia. with light single-piece head, small cone with steel cord sheath and side line sheath pin11mm. internal barrel with sliding piston allowing high speed shaft release and superior power and accuracyLubrication and decreased friction in piston for increase speed and ease of loadingIncludes 7mm. threaded shaft tipTwo year limited warranty
