We are proud to offer and manufacture the Neptonics Full-Length Spearfishing Bungee. It's made with the same quality craftsmanship and detailed construction that our floatlines are known for. It features a 1,600-lb countinuous Spectra core running throughout the line with 200% stretch. The bungee rubber is synthetic, non-decaying rubber and is the perfect setup for those bigger fish.Bungees are different from floatlines, as they keep a constant pull and pressure on the fish and resist the fish as they run, tiring out the fish while not allowing the fish to tear out the shaft. We have used our bungees on large pelagics around the world fighting marlin and yellowfin tuna, and most recently in California on bluefin tuna.
