An alternate way for a sport diver to configure their regulator instead of using a yellow octopus at the end of a long, yellow hose. The streamlined set prevents hoses from dangling and optimizes comfort.In the streamlined configuration, the hose on the primary regulator routes under the diver’s arm and attaches to the second stage with a 90° swivel adapter, optimizing comfort because the hose is no longer tugging on your mouth. The backup regulator, inserted into a regulator necklace, is tucked safely under the chin, allowing immediate access. In an emergency, the primary is donated while the backup is instantly available. The SPG is clipped to the waist D-ring using the snap.FEATURES Vortex DIN First Stage Two Vortex Second Stages 40 in (102 cm) Miflex LP Hose - Black 22 in (56 cm) Miflex LP Hose – Black Vortex Spin-On Yoke – Black Large Highland Black Silicone Regulator Necklace 90º Right Angle Adapter Highland 2 in (5 cm) Brass and Glass SPG w/ PVD finish - Dual Scale 24 in (61 cm) Miflex HP Carbon Hose) Highland 4 in Swivel Bolt Snap 22 in (56 cm) Miflex QD Hose
