The Amero Speargun was designed by our own Jerry Guerra using 100% Teak and 100% Neptonic components for a lifetime of use. This rearhandle speargun features an enclosed track, AR-15 handle, auto-resetting mech, and an oiled finish for easy maintenance. Fully ballasted and balanced. I visited Jerry a few years ago and he took me out diving in Florida. I borrowed his Amero for the day and I absolutely stoned every amberjack. It was the first time that I didn't have to "learn how to aim" a new speargun. It shot so perfectly with such little recoil that I bought Jerry's 60" Amero from him on the boat ride home.
