I bought this Mares Single Tank to go diving in the beautiful Blue Lagoon in Thailand. It’s my first time ever doing a scuba dive and I must say this tank exceeded my expectations! The material feels sturdy and robust, and the build quality is top-notch. However, I do wish there was a built-in pressure gauge, that would have made things a lot easier for me. But overall, I would definitely recommend this tank to fellow divers!

What is the recommended storage capacity for this tank?
Junhao Lo –
The Mares Single Tank AL 7L/50cft has a stated volume capacity of 9L. However, it’s generally recommended to fill your scuba tank up to 90% of its capacity to account for expansion, which for this tank would be approximately 8.1L. This is a safety precaution and can help prevent damage to the tank.
Julie Lim –
Would this tank be suitable for a beginner scuba diver? I’m planning to start diving soon and I want to make sure I get the right equipment.
Imran Hanafiah –
Hello Julie, thank you for reaching out to us about the Mares Single Tank AL 7L/50cft. This tank is a great option for scuba diving, but we would recommend it for experienced divers due to its higher capacity. For a beginner, a smaller tank with a lower capacity would be more suitable to ensure safety and easier handling. We suggest exploring our selection of beginner-friendly tanks that are specifically designed for new divers. Our customer service team would be happy to assist you in choosing the right equipment for your needs. Please feel free to ask us any further questions.

Does the tank come with any built-in safety features?
Junhao Lo –
Yes, our Mares Single Tank AL 7L/50cft features a built-in overpressure valve that automatically opens if the pressure inside the tank exceeds a safe level. Additionally, the tank is also designed with a non-return valve to prevent backflow. Both of these safety features are in place to ensure your safety while diving. If you have any further questions or concerns, please feel free to ask. We’d be happy to help! Some of our other customers have also asked questions about safety features, so we’ve created a knowledge base article to help answer some of the most common questions. You can find it by going to ‘Product Support’ tab on the product page.
