Lynette Wong –
What if I need to use it in colder water temperatures?
Junhao Lo –
Thank you for your question, Lynette! The Mares Loop 15X Regulator is indeed designed for diving in various water temperatures. This regulator features a unique internal heat exchanger that helps to reduce the cold water effect, making breathing more comfortable. In colder water temperatures, the Loop 15X provides a more reliable and efficient performance. We’ve had numerous customers report great experiences using this regulator in temperatures as low as 40°F (4°C). However, it’s always a good idea to consult your local dive center for specific recommendations and guidelines for diving in colder waters.

Can I use the 15X with my existing BCD?
Imran Hanafiah –
Thank you for your excellent review of our Mares Loop 15x Regulator! You can use the 15X regulator with your existing BCD, but it’s essential to ensure compatibility. Our regulator is designed to work with a wide range of BCDs, but we recommend checking the manual or contacting our support team for specific guidance. We’d be happy to help you determine if your BCD is compatible with the Loop 15X.

Natalie Ong –
How does the 15X compare to the Mares Prestige?
Junhao Lo –
Thank you for reaching out, Natalie! The Mares Loop 15X and Prestige are both high-end regulators, but they have some key differences. The Loop 15X features a more compact design and is designed for technical diving, with a higher intermediate pressure and a more efficient purge valve. In comparison, the Mares Prestige is designed for more recreational diving and has a more intuitive user interface. Both regulators have excellent performance and are built to last, but the Loop 15X is a better choice for divers who prioritize a more streamlined design and advanced features. I hope that helps!

Unfortunately, the Loop 15X did not live up to its hype. The high price was not justified by the slight improvement in performance. It’s reliable, but I’d expect more for over $1,400.
