The pneumatically-balanced ZEO is an engineering marvel of precision, durability and comfort. Its durable chrome-plated marine brass metal valve delivers a phenomenal breathing experience, improves cold-water performance and helps recirculate moisture from exhalation to prevent dry mouth. The breathing adjustment gives the diver a wide range of control to precisely set airflow throughout the dive. The ZEO comes standard with an in-line hose swivel, inhalation effort control, dynamic adjustment technology dive/ pre-dive switch and a super comfortable orthodontic mouth piece featuring an inline ball swivel on the hose connection to eliminate the binding that can cause jaw fatigue. DESIGNED FOR DEPTH Try telling an engineer that a design, any design, can't be made‚Ķ better. In our case that challenge led directly to the ZEO. We started with the EOS, a legendary regulator known for its comfort and breathing profile and ended up with the ZEO. Like its predecessor the EOS, the ZEO is also a phenomenal breather allowing the diver extensive control over the air flow profile at any depth. It takes this design one step further however by incorporating a tough and corrosion resistant chrome plated marine brass valve that has better cold water performance and even a better breathing experience. The all metal valve encourages the condensation of water vapour from your exhalation on the valve housing. When you inhale that condensed water vapour circulates with the airflow and helps to reduce "dry mouth" and increase the overall level of comfort. The ZEO also comes with our patented Dynamic Adjustment technology, diver inhalation effort adjustment controls, dive/pre-dive switch, swivel and a super comfortable orthodontic mouth piece.
