Ermes Avatar three 3 band speargun muzzle with optional shark deterrent spike. For speargun barrels with 26mm or 26.5mm inner diameter. Quickly elevates bands onto the plane of travel of the spear with the built in band channels. Manufactured in extremely durable impact resistant plastic. Shooting line can be routed to the right or left side. Bungee anchoring point/reel line guide/ 2nd wrap line guide are built in. Accepts three 14mm, 16mm or 19mm bands. Includes two incorporated O-rings to prevent water intrusion into the tube. Peg insert diameter is 26mm with sacrificial stripes that increase the diameter to 26.5mm. These stripes can be easily cut or sanded off, allowing compatibility with 26mm and 26.5mm inner diameter aluminum and carbon speargun tubes. Muzzle material can be filed or sanded reducing the peg diameter and/or track height, making it possible to fit many tube configurations. Stainless steel screw for installation is included.

The front end of the Ermes 3 hole muzzle has a built in threaded hole. This hole accepts the optional threaded shark spike. The shark spike can be quickly and easily added or removed from the muzzle, partially by hand or all the way in for a tight fit with a wrench or pliers. After shooting a fish a diver is normally left vulnerable, with a spent speargun amounting to nothing more than a stick between them and an aggressive shark. With a sharp shark spike the shaft-less speargun becomes an effective self defense tool.
