Constructed of rugged stainless steel, JBL's fixed Spearpoints are a perfect blend of durability and performance. Each point is designed for low maintenance, dependability and most important...results. Paralyzers stop reef fish dead in their tracks, and the trident is exceptional for bottom fish whether on a speargun or a polespear. Whatever point you choos if it's from JBL you know you're getting your money's worth.
