The TSS Coral Sport was designed with both freedivers and scuba divers in mind. Due to its straight forward design the Coral Sport provides perfect flexibility during use, without creating air flow interruptions. The Coral Sport’s anatomical profile is hydrodynamic and reduces vibrations and noises during underwater motion. The mouthpiece is made from high-grade silicone and makes it ideal for prolonged use during breath-hold based diving excursions.
