Torelli Trimax muzzle has four different heads easily created by removing a simple stainless steel and installing one of three options. There is no need to remove the muzzle or power band from the barrel. Please select option required. Wing - Most common and preferred option in Australia, the rubbers are aligned with the spear. Open High - Special designed side pillars solves the annoying problem of the spear falling sideways before securing with the shooting line yet still allows perfect sighting and because the spear is held down by the shooting line there is no spear rattle (especially important for Snapper Snooping). Open Low - Low ridges to suit spearguns with tabbed spears. Closed - A simple bridge to secure and guide spear this option is a favourite of experienced spear fishers.
