I recently went scuba diving with the Problue RO-17A ADJ and I was thoroughly impressed by its performance. The regulator felt very responsive and easy to breathe with, even at depth. I was able to adjust the gas flow with ease using the diver adjustable control knob.
Samuel Teo –
I’ve been looking for a new scuba regulator and was wondering if the Problue RO-17A ADJ is a good option. Can someone tell me more about the exhalation effort and inhalation effort of this regulator?
Imran Hanafiah –
Hello Samuel, thank you for considering the Problue RO-17A ADJ as your next scuba regulator. The exhalation effort of this regulator is relatively low, at 1.0 CIW (Column inches of water), which means it requires less effort to breathe out while underwater. The inhalation effort, on the other hand, is between 1.0-2.0 CIW, which is still relatively comfortable. This regulator features a venturi control assist, which helps to optimize the work of breathing and reduce the effort required for both inhalation and exhalation. I hope this information helps you make an informed decision.

I’ve been using the Problue RO-17A ADJ for a few months now and I have to say that it’s been a game-changer for my scuba diving trips. The pneumatically balanced design really makes a difference in terms of performance at depth.

Can someone tell me if the Problue RO-17A ADJ is suitable for open circuit diving or rebreather diving? I’m thinking of purchasing this regulator but want to make sure it fits my specific diving needs.

Thank you for reaching out about the Problue RO-17A ADJ Second Stage w/Silicone Cover Regulator. According to our product information, this regulator is designed for open circuit diving. It features a pneumatically balanced design, a diving adjustable control knob, and a venturi control assist for excellent work of breathing. The maximum intermediate pressure of 145 PSI makes it suitable for most recreational and technical open circuit diving applications. However, we recommend consulting the manufacturer’s documentation for specific guidelines on its use in rebreather diving. We appreciate your feedback and hope you find this information helpful in your purchasing decision.

I’m not sure about the durability of the Problue RO-17A ADJ, but I will say that it feels like well-made and relatively heavy. Is there a lockout feature on the regulator, and if so, how does it work?
Imran Hanafiah –
Thank you for sharing your thoughts on the Problue RO-17A ADJ, Lena! We’re glad to hear that you appreciate the appearance and construction of the regulator. Yes, our regulators do come with a lockout feature to prevent accidental air flow. The lockout feature is activated by rotating the adjustment knob to its fully clockwise position, where the diaphragm is isolated from the air source. This ensures that no air can leak through the regulator when not in use. Please let us know if you have any further questions!

I recently purchased the Problue RO-17A ADJ and I’m happy with its performance so far. However, I did experience some minor issues with the large oval exhaust valve – it can get stuck sometimes. Is this a common issue with this regulator?
