Can I use this regulator for both scuba diving and snorkeling? Would appreciate any advice on this.
Junhao Lo –
Dear Emily, Thank you for reaching out about using our Problue FS-900 1st Stage Regulator – Yoke for both scuba diving and snorkeling. This regulator can be used for both purposes.

Evelyn Wong –
Will upgrading to a yoke type first stage drastically increase the water flow?
Imran Hanafiah –
Thank you for your question, Evelyn! The upgrade to a yoke type first stage regulator can indeed improve water flow, but it’s not necessarily drastic. Our Problue FS-900 1st Stage Regulator – Yoke is designed for high flow rates, providing 135 SCFM at a 3000 psi air supply. This makes it suitable for a variety of diving applications. However, the actual water flow will also depend on the rest of your diving system, including your second stage regulator, hoses, and other components. If you’re looking to increase water flow, we’d be happy to help you choose the best configuration for your needs.
