The Ocean Hunter Phantom Purge Snorkel featuring an advanced lower purge system that significantly enhances water clearing efficiency. Its hydrodynamic tube design—streamlined, contoured, and flexible—provides optimal performance during technical cave diving and crayfish hunting expeditions. The premium silicone mouthpiece ensures extended durability while maximizing comfort during prolonged use. The innovative purge mechanism operates on a simple yet effective principle: water naturally collects at the lowest point where a specialized one-way valve allows for effortless clearing with minimal exhalation pressure, eliminating the traditional forceful clearing method and maintaining respiratory efficiency throughout your dive.
