Originally a DIY solution in the early days of technical diving, the regulator necklace was a must-have for keeping a backup second stage secure and instantly accessible. Back then, divers made their own using bungee cord or surgical tubing—but now, Highland offers a premade, professional-grade version that’s ready to go out of the box.

Made from durable, no-memory silicone, this regulator necklace keeps your backup second stage positioned just under your chin, allowing for quick deployment in an out-of-air emergency or when diving in overhead or team environments. It’s ideal for tech, sidemount, rescue, and instructor use—plus recreational divers who want to dive smarter.

Key Features:

Originated in tech diving—now professionally made

Attaches easily to any standard second stage mouthpiece

Keeps your alternate air source close and always ready

No-memory silicone resists twisting and stretching

Durable and compact—perfect for any dive configuration
