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.

Hazwani Hussin –
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.

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.

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.
