## Overview

Featuring left/right hose reversibility, adjustable breathing effort, and a highly efficient heat exchanger, it ensures smooth, reliable performance even in temperatures below 10°C.

## Description

The XTX50 Octopus is a high-performance alternate air source designed for reliability and ease of use in demanding diving conditions. Built to deliver smooth, consistent breathing, it features a pneumatically balanced second stage and is suitable for cold water diving environments. Designed with visibility and versatility in mind, it includes a high-visibility yellow front cover and a 36-inch yellow hose for easy identification in emergency situations. The regulator can also be configured for left- or right-hand hose routing to suit individual diver preferences (adjustment must be performed by an authorized technician). With user-friendly controls and durable braided hoses, the XTX50 Octopus offers dependable performance and comfort for both recreational and advanced divers.

Review: Better than any primary I’ve used - This is an awesome regulator and requires almost no effort to breathe. Sits perfectly in the mouth and has the same air flow adjustability as the primary. If I didn’t also have the XTX50 primary, I’d be jealous.
Review: Very low quality product. Not reliable. - Four dives!!! It’s all that this supposed premium gear lasted. On mi fifth dive the hose broke and started loosing air, forcing me to abort the dive. Fortunately the dive boat had a spare hose and I was able of changing it. Total crap.

### ⭐ Very low quality product. Not reliable.

Four dives!!! It’s all that this supposed premium gear lasted. On mi fifth dive the hose broke and started loosing air, forcing me to abort the dive. Fortunately the dive boat had a spare hose and I was able of changing it. Total crap.

### ⭐⭐⭐⭐⭐ It's Apeks...It's Great
*by A***E on September 26, 2018*

With my tech set-up, I use this as my primary second stage. Absolutely the same as the standard all black XTX 50! I have had my original XTX 50 for a year now and it is just flawless. I added the Octo XTX 50 to complete the revamping of my older equipment and literally "Breathe Easier".
