A Review

Catalina 80 Dive Tank Review


As the saying goes, the bigger a thing is, the better it is. That applies to scuba diving tanks too. The bigger the size of the tank per cubic foot, the better the dive experience, especially in deep diving. The Catalina 80 dive tank has that exact quality because it features an 80 cubic foot size cylinder which has the ability to carry more gas (air) giving you a longer time under water. In this Catalina 80 Dive Tank review, we will expose on all the intricacies and qualities that this ideal dive tank delivers while hinting on its merits and demerits too.

In scuba diving, the standard cylinder size is 80 cubic foot. This is chiefly because of the volume of gas it can carry and the longer time span it gives scuba divers to explore the world of aquatic splendor down below. As already hinted above, that is just what the Catalina 80 dive tank gives you.

Given the size of this high-grade scuba diving cylinder – which is placed at some 8.0 inches in diameter (20.37 cm) and weighs 46.9 lbs. (21.27 kg) – it is best suited for advanced level and professional scuba divers who want to perform some deep underwater dives. This does not leave out the recreational and beginner divers as the Catalina 80 dive tank gives them more gas level to play around with underwater. It is made of a perfect combination of chrome-plated brass, high-grade rubber and plastic.

On top of that, it has a convertible valve such that accommodates you whether you dive with the yoke or DIN valves. To further highlight the super functionality and design of the Catalina 80, it has a heavy-duty deign that is crafted with a smooth operating mechanism and a burst disc plug with multiple ports for added safety.

This scuba diving tank is made of aluminum and carries 80 cubic feet of air which is good for a deep dive. This versatile tank can be filled with nitrox or a regular mixture of enhanced oxygen. Designed with an ingenious bottom-weight feature, the tank has more weight on the bottom which allows the diver to maintain a heads-up position as the scuba tank weighs downward on the back of the diver.

Catalina 80 is made from good grade aluminum, so you don’t have to worry about rust or corrosion coming to your precious tank. Also, aluminum is far less weighty when compared to steel, so it means that the Catalina 80 dive tank is much more lightweight for every diver.

Because of its highly regarded buoyancy characteristics, the Catalina 80 aluminum cylinder has been heralded as a popular diving cylinder choice by technical divers who want to engage in deep water diving, or on very long dives. For longer, deeper dives they often use these cylinders to carry a Nitrox mix (e.g. EAN50, 50% oxygen) to accelerate their decompression on accent. The Catalina S80 is a great cylinder for doing this.
