Apeks XTX50 Plus XTX40 Set Regulator


£582.25 £649.00
Manufacturers Description


The Apeks XTX 50 and XTX 40 Octopus regulator package is an excellent set for divers who need ultra-reliability and performance in even the coldest of conditions.

The DST first stage uses a high-performance diaphragm design with the additional benefits of an environmental seal for cold water protection. The DST is fitted with a swivelling low-pressure turret that houses four low-pressure ports. Two high-pressure ports can also be found on the main body of the first stage.

The XTX 50 is supplied with a flexible braided hose for improved safety and prolonged hose life. The second stage features diver adjustable inhalation and venturi controls to modify the performance and safety characteristics of the valve. An interchangeable exhaust cover gives the diver the choice between a wide cover designed to deflect the exhaled gas away from the face or a much more compact cover for reduced drag and weight. The housing is also reversible which allows a technician to swap the hose handing from right to left if required.

The XTX 40 is supplied with a longer yellow braided hose and high visibility trim and cover. The octopus uses the same internal mechanism and provides the same level of performance as the XTX 50 but lacks the external inhalation adjustment and the additional interchangeable exhaust cover (compact cover fitted as standard). The housing is reversible as per the XTX 50.

Outstanding set of regs, very pleased with them! Mouth piece is very comfortable, overall build quality at a very high standard.

In my opinion, probably the best in the world. Ex- forces with 40 years of diving under my old belt I have used variants of this product at work and for recreation. You cant ask for better. Why am I buying now? My son stole my original set which w

I think these are an amazing set of regulators compared to some of the more expensive brands that are about the same price for just the first and second stage alone without the Octo! The mouthpiece is really comfortable compared to other regulators I have used, and having the interchangeable exhausts was really handy because I don't like the bubbles getting in my face. I love that the first stage swivels as this, alongside the flexible braided hose, stops my head movement being restricted. I like to have as much freedom to move as possible when diving. The breathing is very easy and all in all, these are just some very sturdy regs! The only reason I rate 4 stars instead of 5 is that after only 11 dives, the O-ring blew on my first stage, I wasn't sure if this was a fault with the regs or how they were put together, but a simple replacement and good tightening has solved this problem easily. These things happen! Cannot flaw the regs otherwise :-D

As a new diver this was my first own set. Bought with intention to last so the 2HP ports are essential. Felt extremely comfortable in my mouth, easy to set up. The hosing is well made and I got the impression the regs were bullet proof. Used for the first time at the weekend with no issues and I felt completely at ease. Obviously I only have experience with club regs, but as a starting out piece of kit I was very happy.

Easy breathing and durable.

Upgraded my first ever regs (pretty pink travel set) to this setup. I love em! Easy to breath, super durable, look the business and suitable for all-sorts of environments. Worth the investment, hopefully these will see me into my retirement diving (many years from now haha!)
