OMS submersible pressure gauges (SPG) comes with the “O” ring swivel that is needed.
These gauges are light, small and perfect for stage bottles or people that are just looking for a smaller gauge.
They seem to be great bootie’s 👍
Nice top Grandson loved it
Honestly I’ve never had a mask so well fitting and so comfortable. The low profile single lens really makes you feel more immersed in the diving scenes😍
Just perfect
Great product
