🤿 Dive Avenue's expert opinion on the Octopus 1Dive

What I like about this Octopus is its 'all-terrain' aspect. It's rare to find a second stage that's so easy to maintain. Its mechanical simplicity is its greatest strength: fewer moving parts means less risk of breakage. It's the ideal octopus for those who want reliable, lightweight backup equipment that is, above all, very intuitive to purge in an emergency.

❓ Frequently asked questions (FAQ)

Is it compatible with my regulator from another brand ? Yes, the Octopus 1Dive uses a standard connection and can be mounted on most first stages on the market. However, intermediate pressure adjustment may be necessary for optimal comfort.

Why should it only be used in water above 10°C ? Its non-compensated design is optimised for simplicity and robustness in temperate waters. For ice diving or diving in very cold waters, specific models with heat exchangers are recommended.

Is the hose included ? Generally, this octopus comes with a high-visibility yellow hose of standard length for easy identification and switching to a buddy.
