Product Information
The Hollis Regulator Necklace is an adjustable bungee cord accessory that holds a backup second stage securely under the chin, keeping it in a known position for fast recovery during a dive. It is built from butadiene rubber bungee cord and is a staple accessory in technical and sidemount regulator configurations.
Who it is for
This necklace is for divers who want their backup second stage held in a consistent, predictable spot rather than dangling or tucked into a BCD pocket. Technical divers and sidemount divers commonly use this style of necklace because it frees the hands and keeps the alternate air source ready for an immediate, no-look grab in an out-of-air or share-air situation.

Frequently Asked Questions
What is the Hollis Regulator Necklace made of?
It is made from a butadiene rubber bungee cord. This stretchy construction lets the necklace hold a backup second stage securely under the chin while flexing with head and body movement during a dive.
Can the Hollis Regulator Necklace be adjusted for different exposure suits?
Yes. The necklace length is adjustable, so divers can fit it to their body size and exposure suit thickness.
Why do technical and sidemount divers use a regulator necklace?
A regulator necklace keeps the backup second stage in a known, consistent position below the chin instead of floating free. This makes it a standard practice in technical and sidemount configurations, where quick, no-look recovery of the alternate air source matters.
Does the Hollis Regulator Necklace fit any second stage?
The necklace is designed as a regulator-specific accessory to hold a backup second stage under the chin. For fit with your specific second stage model, contact DiveCatalog.com so we can confirm compatibility before you buy.
