I wonder, how well does it work in cold water?

I’ve been using the Problue FS-850D 1st Stage Regulator – DIN for a few months now and I must say, it’s been a game-changer for my diving expeditions. The over-balanced diaphragm design provides superior breathing performance, even at increased depths. The corrosion-resistant marine brass construction has also withstood the test of time.

What’s the recommended maintenance schedule for this regulator? Would like to ensure that I keep it in top condition.
Imran Hanafiah –
Dear Emily, thank you for your review and question about the maintenance schedule for the Problue FS-850D 1st Stage Regulator – DIN! To ensure the longevity and performance of your regulator, we recommend a bi-annual maintenance check with a certified technician. Regular maintenance tasks include checking the reg’s O-Rings and seals for wear and cracking, cleaning any debris from the intake ports, and inspecting the hose for kinks or damage. These checks help to prevent potential issues and keep your regulator in top condition. Please refer to the user manual for detailed instructions and maintenance schedules. If you have any further questions, feel free to ask!

As a seasoned diver, I was initially skeptical about the Problue FS-850D’s performance. However, after using it for a few dives, I was impressed by its reliability and superior breathing performance, even in cold water. My only minor complaint is that the knob for adjusting the regulator could be more user-friendly.
Sunita Tang –
I would say that the Problue met all of my expectations in terms of performance.
Izham Abdullah –
Is it compatible with my existing dive tanks? Would love to know more about the Yoke type and Din type features.
Junhao Lo –
Thank you for your review, Izham. The Problue FS-850D 1st Stage Regulator is compatible with dive tanks featuring either a Yoke or DIN port. Regarding the Yoke type and Din type features, the Yoke type (FS-850) is designed for use with yoke-mounted tanks, while the Din type (FS-850D) is designed for use with DIN-locked tanks and Yoke on DIN convertors. The regulator’s high-pressure port is (7/16 ?-20 UNF) x 2 and the low-pressure port is (3/8 ?-24 UNF) x 4.

Using it every weekend while snorkelling and it’s solid, the Problue works fine with our dive lights.

I see the product includes a high-pressure port ( 7/16 ?-20 UNF ) x 2, however, what kind of attachments can I get for it?

We recommend checking with your local dive shop or online retailers for compatible attachments. If you need any further assistance, feel free to contact our support team.
Natalie Lee –
I’m not completely satisfied with the ventilation rate, at 135 SCFM for 3000 psi, it might be slower for a bigger group of divers, but overall still worth it.
Ridwan Ghazali –
I recently purchased the Problue FS-850D 1st Stage Regulator – DIN and have been thoroughly impressed by its performance. The regulator is easy to use and the breathing performance is smooth and consistent. The only minor negative aspect is that the low-pressure port could be more secure, but overall, I’m extremely satisfied with this purchase.
Alison Koh –
The Problue is easy to use and maintains excellent reliability.
