PRO PACK HELIX PRO DIN + OCTO SPG BAG

The Aqua Lung Helix Pro Pro Pack is a complete gas-delivery set built on the Helix Pro regulator, with the matching octopus, a pressure gauge and a padded regulator bag in the same box. At 2880 g it is the lighter of the two Aqua Lung pro packs.

The first stage is over-balanced with an Auto Closure Device and a sealed environmental chamber, weighs 525 g in DIN, and is rated to 300 bar. Two high-pressure ports in 7/16 inch UNF and four medium-pressure ports in 3/8 inch UNF carry the primary, the octopus, an inflator hose and the gauge. Work of breathing on the primary is 0.95 j/L. A heat exchanger and a lip shield on the second stages slow ice formation, and the gauge assembly adds 205 g. The regulator is supplied ready for nitrox up to 40 percent oxygen.

The result is a cold-water set with everything routed and matched from new, at a weight that survives an airline allowance.

Supplied with first stage, primary second stage, octopus, pressure gauge and bag. A transmitter and the DIN to yoke adaptor are sold separately. The bag is a padded regulator bag and not a full gear bag, so it travels inside a larger case. The Leg3nd Elite Pro Pack is the colder-water alternative, at a higher price and 470 g more weight.
