Nautilus 23mm Button Gauge Details
The Nautilus 23mm Button Gauge is designed for divers who want a minimalist and reliable way to monitor cylinder pressure. By threading directly into the regulator’s HP port, it removes the need for bulky hoses and reduces potential snag points — making it especially popular with pony bottle, stage, and sidemount setups.
Its compact design makes it ideal for backup use or for divers who want to quickly check tank pressure without adding unnecessary bulk to their system. The clear pressure scale provides an easy-to-read indication of available gas, while the robust UK-made construction ensures durability in demanding dive environments.
Whether used as a permanent pony bottle gauge or kept as part of your save-a-dive kit, the Nautilus Button Gauge offers simple, effective pressure monitoring in a small package.
