Will the R2S-VR Regulator fit a 7/16 female DIN Yoke adapter?
Imran Hanafiah –
Thank you for your question, Elijah! We’re happy to help. The Mares R2S-VR Regulator has a Euro-style first stage, which works with both DIN and yoke second stages. The regulator is designed to be very versatile and can accommodate various adapters. However, we recommend using a yoke adapter with a male 7/16 thread to connect it to your yoke valve. Therefore, the regulator should fit the 7/16 female DIN Yoke adapter without any issues.

What’s the lifespan of the seal on the R2S-VR first stage?
Junhao Lo –
Thank you for your question, Amanda Teh. The Mares R2S-VR Regulator’s first stage is designed to last long, but we recommend replacing the seal after every 50 dives or 12 months, whichever comes first. This will ensure the optimal performance and safety of your regulator. For more information on maintenance and care, please refer to our user manual or contact our customer support team.

The Mares R2S-VR Regulator really exceeded my expectations with its seamless and responsive delivery. It’s easy on the lungs and provides consistent flow, even at mid-water depths. I love how it comes with a reliable R2 first stage and a vertical second stage which makes for a perfect combination for both dive staging and shared breathing.
Kevin Lee –
Overall, I’m thoroughly impressed with the performance of the Mares R2S-VR Regulator. It’s an excellent choice for any diver, beginner or advanced. However, I did notice a slight leak in the first stage, but it didn’t compromise its overall reliability. Perhaps Mares can improve on this aspect in future models?
Junhao Lo –
Thank you for taking the time to share your experience with the Mares R2S-VR Regulator, Kevin. We’re glad to hear that you’re impressed with its performance and that it’s met your expectations. We take your feedback about the slight leak in the first stage seriously and will pass it on to our product development team. We’ll look into ways to improve this aspect in future models. In the meantime, we recommend checking the seal on the first stage periodically to ensure a tight fit. Have any further questions or concerns?

Do you have any experience with the R2S-VR Regulator for cave diving?
Junhao Lo –
Thank you for reaching out to us about your interest in using the Mares R2S-VR Regulator for cave diving. While we don’t have specific experience with this regulator in a cave diving environment, we can tell you that it’s designed to be extremely reliable and compact, making it ideal for traveling and decompression stages of dives. It’s also designed for ease of use and comfort, which could be beneficial in a low-light, confined space like a cave. We recommend consulting with a dive professional or expert in cave diving to get a better understanding of how this regulator would perform in that specific context.
Sophia Low –
I was blown away by how easy it was to breathe underwater using the R2S-VR Regulator. The travel stage is so comfortable and the decompression stage is a breeze. Perfect for long dives!
Melissa Wong –
What makes the R2S-VR Regulator unique compared to other regulators on the market? Is there a specific design feature that sets it apart from its competitors?
Junhao Lo –
It’s great that you’re interested in learning more about what sets our R2S-VR Regulator apart. One of the key features that makes it unique is its vertical second stage design. This innovative design allows for a more compact and streamlined regulator that’s both comfortable and easy to handle. The R2S first stage is also extremely reliable, making it a perfect choice for both travel and decompression stages of your dives. Buddy breathing is also made easy with this regulator. Our design team worked hard to create a regulator that’s both functional and user-friendly, and we’re proud to say that it stands out from the competition.
Daniel Ng –
This regulator has undoubtedly improved my diving experience. The vertical second stage is incredibly convenient and I appreciate the durable construction. One minor criticism is that the R2S-VR could benefit from a bit more ergonomics in the design to fit smaller-handed divers like myself.
Lilian Wong –
The R2S-VR Regulator is a beast! I took it on a week-long dive trip to the Great Barrier Reef and it performed flawlessly. The comfort and ease of use were a game-changer.
Eugene Lee –
Does it come with a built-in dive computer? Does it support both air and N2O cylinders? Can you recommend a reliable dive computer that works in sync with this regulator?
Junhao Lo –
Thank you for your review, Eugene Lee. The Mares R2S-VR Regulator does not come with a built-in dive computer. It’s designed to be a reliable first and second stage regulator. For your first question regarding support for both air and N2O cylinders, we’d like to clarify that the R2S-VR Regulator is designed to be used with air cylinders, and we recommend using a separate dive computer. We can recommend the Mares Puck Pro Dive Computer, which has been designed to be user-friendly and compact, making it a great option for diving. It’s also compatible with our reg system for seamless syncing.
Kevin Chan –
The R2S-VR Regulator is a solid regulator, but it didn’t quite live up to my expectations in terms of reliability. The first stage had a minor leak, but it was easy to fix. Still a great value for the price.
Rachel Chan –
What types of diving can I use this regulator for? Is it suitable for technical diving or only recreational diving? Would it hold up to the rigors of a long, deep dive?
Imran Hanafiah –
Thank you for reaching out to us, Rachel! The Mares R2S-VR Regulator is designed for a variety of diving applications, including recreational diving, technical diving, and even commercial diving due to its reliability and performance. The R2S first stage and VR second stage combination is built to handle the rigors of long, deep dives. It is also a popular choice among traveling divers due to its compact size and ease of use. For technical diving, the VR Second Stage offers a high flow rate, which is beneficial when navigating complex dive sites or when performing decompression stops. Additionally, the R2S first stage is designed to be highly resistant to freezing and contamination, providing a safe and reliable breathing experience even in challenging diving conditions. However, as with any regulator, it’s essential to properly maintain and inspect it before each use to ensure optimal performance.
