Spearfishing is the most eco-friendly way to catch and consume fish. With zero bycatch and ghost gear left behind spearfishing has a minimal impact on an ecosystem as hunters will only take what they want and need.
Spearfishing takes skill and specialist equipment to do it properly and mirrors the similar freediving range of gear. Low profile masks and long fins paired with open cell neoprene wetsuits mean you can stay in the water longer. Spearguns come in a range of designs and lengths for different needs.
