Its highly efficient heat exchanger guarantees excellent performance in frigid environments, all packed in a lightweight, compact design trusted by serious divers. ## Description The XTX50 Octopus is our top-of-the-line Octopus in terms of features and performance. It provides the same features and performance as the XTX50 second stage and includes left / right hand reversibility. It comes with a high visibility yellow front cover and a 36" yellow hose. Suitable for cold water use (below 10 C / 50 F). Feature and Benefits The XTX50 Octopus has a breathing effort control knob. This allows the diver to desensitize the unit when it not being used. The XTX purge buttons are large and easy to operate. A 2-stage progressive purge is used - press the purge on the side for a lower flow rate, useful where more control is required such as filling lift bags etc, then press in the centre for the full effect of the purge, i.e. when regulator clearing etc. Can be converted from a right-handed hose configuration to a left handed one. The process of changing the regulator to a left-handed configuration is both quick and simple. However, this procedure must ONLY be performed by an APEKS Authorised Service Technician. Braided flexi-hoses are now standard on all models. These hoses are lighter weight, more flexible and more durable. Suitable for coldwater use. Compatible with EAN40 out of the box. Pneumatically-balanced second stage results in smooth, easy breathing. The large venturi lever has a soft touch rubber grip, which makes it easier to locate and use. The lever reduces the amount of grit ingress and therefore resists any possible friction giving a smooth operation.

A silicone exhaust valve improves 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: It's Apeks...It's Great - 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". ## Features - Includes left/right reversibility - Cold water capability - Diver-adjustable controls for opening effort and venturi control - Excellent cold-water performance due to the highly efficient heat exchanger ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E5X01CK | | Best Sellers Rank | #244,647 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #3 in Diving Octopuses | | Brand Name | Apeks | | Customer Reviews | 4.5 4.5 out of 5 stars (17) | | Date First Available | October 20, 2013 | | Item Dimensions LxWxH | 1 x 1 x 1 inches | | Item Package Dimensions L x W x H | 9.1 x 7.4 x 5.7 inches | | Manufacturer | Apeks | | Package Weight | 1.45 Pounds | | Part Number | AA0342F | | Warranty Description | This product comes with a full manufacturer warranty. | ## Images ![Apeks by Aqua Lung XTX50 Octo Regulator - Image 1](https://m.media-amazon.com/images/I/61fS0VAyCvL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Better than any primary I’ve used *by B***R on February 19, 2023* This is an awesome regulator and requires almost no effort to breathe.
