Explore the underwater world with the uncompromising performance and reliability of HOLLIS. Engineered for the demanding diver who ventures beyond the ordinary, HOLLIS represents the pinnacle of technical and recreational dive equipment. Every piece of gear is designed with a purpose: to provide absolute confidence, control, and comfort, allowing you to focus solely on the adventure that lies beneath the surface. From deep wrecks to intricate cave systems, HOLLIS is the trusted choice for explorers pushing the limits.

At the very heart of your life support system is the scuba cylinder, and HOLLIS dive tanks are the benchmark for safety, durability, and performance. Understanding that every diver has unique needs, the HOLLIS collection of tanks offers a comprehensive range of options to build the perfect foundation for your dive configuration. Whether you are a technical diver fine-tuning your buoyancy or a recreational diver seeking a dependable air source, there is a HOLLIS cylinder built for you.

Discover our selection of robust HOLLIS steel tanks, a favorite among technical and cold-water divers. Prized for their buoyancy characteristics—starting negatively buoyant and remaining so throughout the dive—these steel cylinders help reduce the amount of weight needed on your belt or harness. Manufactured to the highest standards and often featuring a hot-dip galvanized finish, they offer exceptional durability and superior resistance to corrosion and impact, ensuring a long service life even in the most challenging conditions. Available in various capacities and pressure ratings, including high-pressure (HP) models, these tanks are ideal for single-tank, backmount doubles, or sidemount configurations.

For those who prioritize ease of handling on land and in transit, HOLLIS high-grade aluminum tanks are an excellent choice. Perfect for recreational diving and warm-water destinations, these cylinders offer a fantastic balance of weight and capacity. While they become more positively buoyant as they are emptied, their lighter weight makes them easier to manage on the boat or during shore entries. Each aluminum tank is crafted with precision, ensuring consistent wall thickness and a flawless finish for maximum safety and reliability.

Every HOLLIS dive tank is equipped with a high-quality, reliable valve, often a convertible pro-style valve that can easily be switched between DIN and Yoke, providing ultimate versatility for any regulator setup. This attention to detail ensures a secure connection and smooth gas flow when you need it most.

Build your entire integrated system with HOLLIS. Pair your chosen cylinder with a world-renowned HOLLIS regulator, a streamlined BCD like the Katana 2 or HD200, and powerful fins to create a cohesive, high-performance dive package.

Choose HOLLIS at diveinn and equip yourself not just with gear, but with the confidence to explore deeper, stay longer, and discover the incredible possibilities of the underwater realm
