🤿 The diveavenue expert's opinion

This is where we enter the heavyweight category. The 20-litre tank is a great solution for divers who consume a lot or who want to dive for more than an hour without switching to a twin tank. It is a reliable tank. Underwater, its inertia is a real plus: you feel grounded, stable, and you enjoy what seems like almost infinite autonomy.

❓ Frequently asked questions (FAQ)

Is this tank easy to transport ? Given its volume, it is heavier (around 24-26 kg when empty). We recommend using it with a BCD or a sturdy backplate to distribute the weight evenly. On the boat, a suitable base is essential for stability.

Is it a good alternative to a twin tank ? For those who want air without the complexity of a manifold and two tanks, it is an excellent alternative. It is easier to inflate, transport and maintain, while offering an impressive volume of air.
