Features
Frenzel Flange Left Free Submersible Diving Ear Pressure Balance Artifact
Premium surgical-grade stainless steel flange ensures corrosion resistance and durability in harsh underwater conditions. Precision-engineered left-free design allows effortless single-hand operation during deep dives. Ergonomic contours and laser-polished edges prevent ear canal irritation while maintaining hydrodynamic efficiency. Anodized aluminum pivot joint guarantees smooth 30°-90° adjustable pressure release for equalization at varying depths. Ideal for technical divers, freedivers, and underwater photographers requiring rapid middle ear equalization below 40m. Compatible with all standard drysuit valves and full-face masks. Bulk purchase advantage: wholesale pricing available for dive centers and professional maritime training academies. Ships globally with OEM certification.
