Automatic Aqua Lung HELIX PRO DIN | For technical diving

Product details Regulator Aqua Lung HELIX PRO DIN

Technical diving with the Aqua Lung HELIX PRO DIN automatic will be a joy. This is one of the best automatics on the market in terms of price/performance ratio, with ACD patented automatic closing of the first degree.

Thanks to this, the ingress of dirt into the automatic is eliminated. The closure occurs after removing the diving automatic from the valve of the pressure cylinder. Stage I thus remains lubricated and clean, which guarantees greater safety for Nitrox use.

The automatic is suitable for cold waters, which indicates the PRO flag. This certification indicates that the automatic is for temperatures below 10°C. It also includes a patented heat exchanger surrounding the valve to dissipate the cold that is created when the gas expands. This subsequently heats the valve mechanism to the ambient water temperature.

I. stage is membrane balanced guaranteeing stable performance. For optimal placement of 4 LP and 2 HP ports, it is made in the shape of the letter T.

II. the stage is pneumatically balanced for fluidity and comfortable breathing.

For comfortable use, the automatic has a patented Aqua Lung Comfo-bite™ mouthpiece with a repeatable tightening strap.

Service of this automatic is easy thanks to the common spare parts of Aqua Lung automatics.

The use of a venturi lever prevents freeflow at the surface or improves performance at depth.
