OCEANREEF Neptune III

• Second Stage Regulator: Vertical, body balanced - Neptune III regulator delivers amazingly smooth “silk-like” breathing at any depth. Cold-water CE certified for full-face use.
• The Neptune III air circulation system: designed to minimize fogging and reduce the amount of CO and CO2 build-up.
• The silicone oral-nasal pocket: built with two one-way valves through which air is inhaled.
• 3D Equalization System: The Neptune III is equipped with a patented internal device to close the nostrils and allow underwater equalization. Patented design 3-way directional adjustment system (up/down, wide/narrow, close/far) to push the mask towards the face when needed causes the plugs to create a nasal seal.
• Dive/pre dive lever (Venturi): it gives additional control over free-flow tendencies at the surface or in current.
• Purge Button: it manually releases a strong flow of air through the regulator to quickly expel any water that has entered the mask.
• Surface air valve: it allows IDM divers to breath ambient air when at the surface.
• Face Seal: patented bellows double “S”, “spring profile”, skirt. Super comfort thanks to the “floating effect” on the face.
• Visor: Transparent polycarbonate with both sides coated in siloxane resin for improved scratch, chemical resistance and a better light transfer. Impact resistance tested by STANAG 4296 standards: impact of a steel ball traveling at 540 kph (335 mph).
• Field of vision: Larger field of vision than competitors (italcert Certification PPE-05 Rif 1332/05).
• Extender Kit: an add-on frame and accessories system. It adds protection, mounting options for cameras/lights/comms, and customization.
• Head Harness: six straps meaning no risk of losing reg if unconscious or violently hit.
• Fast rotating buckle system: for comfortable and quick doffing and donning on the surface and secure, fast operations during underwater bail out or wearing.
• Doffing Handle: one-hand quick-release handle that attaches to the Neptune III’s quick release system to make removing the mask easier.
• Neptune III Backpack: Purpose-built for scuba divers with mask compartment for smart and quick access to your Neptune III and high-capacity lower compartment with draining mesh for first stage, hoses, octopus.
