The Apeks Tek3 First Stage is specifically designed to be used with twin cylinder configurations.

Apeks Tek 3 1st Stage

The Apeks Tek 3 1st stage has been specifically designed to offer a solution to your twin-set diving needs. The body’s of the 1st stage mirror each other allows for considerably neater and more efficient hose routing.

Apeks have also ensured the Tek 3 meets the demands of technical divers. The overbalanced design provides you with the same level of incredible performance no matter how deep you descend in the water. It’s also environmentally sealed; this prevents ice build up and contaminants getting into the system for superior cold water performance and safety respectively.

Key Benefits

Designed for Twin-Sets - The Apeks Tek 3 design is highly specialised to offer optimal routing for complex technical Twin-Set rigs. The left and right 1st stages ports mirror each other (rather than being the same on both sides), this ensures routing your hoses is less cluttered and more streamlined.

Compact One Piece Body - The rugged one piece body has been chromed, not only does it looks incredible but also ensures the Tek 3 is exceptionally tough and easily shrugs off the abuse of diving.

Superior Deep Water Performance - Explore the deepest and most extreme Scuba environments with the Tek 3. When you descend into deeper water the ambient water pressure surrounding you and your hoses increases. This impedes the flow of air through your hoses making breathing more difficult. The Tek 3’s Overbalanced design counteracts this by increasing the air pressure the deeper you dive ensuring you receive consistent effortless breathing throughout your dive.

Environmentally Sealed - Exploring the deepest seas can be treacherous! The Tek 3’s environmental seal serves two purposes. Firstly it protects the 1st stage from ice buildup allowing it to function in sub 10*C temperatures. Secondly it prevents contaminants such as bacteria or water borne diseases getting affecting your air supply.

Suitable for Cold Water - The Tek 3 has been tested and rated down to 60 meters in cold water.

Who is the Apeks Tek 3 1st Stage For?

The Apeks Tek 3 is the ultimate solution for scuba divers using twin sets. Built to handle the rigours of extreme technical diving there are few environments too extreme for this 1st stage.

Whether you’re exploring around the UK or abroad, the level of performance on offer leaves little to be asked.

Understanding Apex Regulators

Apeks regulators are some of the most popular on the market (and certainly our biggest seller!). Whether you’re a UK diver tackling icey-cold conditions or a tropical undersea explorer, Apeks regs are known for their uncompromising reliability, performance and engineering.

As a UK born brand, Apeks have over 30 years of experience developing regulators for our truly brutal conditions and there’s a good reason why they’re seen so often among experienced divers.

Whether you’re looking for your first reg on a tight budget or an experienced diver looking to enjoy the performance of a top-level regulator it’s worth knowing what you’re getting for your money and the differences between the various models in Apeks’ range.

Technology

What goes into an Apeks Regulator? As a leading brand in diving technology, Apeks use a host of advanced technologies to deliver impressive performance.

Overbalanced Diaphragm Design

If you intend to take on seriously deep water an overbalanced first stage is a blessing. When you descend the ambient pressure around you compresses your gas/air, restricting flow between your first stage and second stage and making breathing more difficult. The deeper you go, the greater this effect.

While all regulators counteract this effect to some degree by gradually increasing the rate of pressure through your hoses, overbalanced regulators increase the rate of inter-stage pressure at a much greater rate than normal first stage designs ensuring breathing is easy no matter the depth you’re diving at.

The over-balanced diaphragm design is found on Apeks Tungsten, XTX200, XTX100, XTX50, XTX40 and XTX50/DS4 first stages.

Environmental Dry Sealing System

Nearly all Apeks regulators are environmentally sealed.

Firstly, this prevents ice buildup on the main spring that can occur in extremely cold water and cause freeflow (when your regulator ‘freezes’ open, wasting air).

Secondly, the seal prevents contaminants like silt or microbes from entering the system and potentially harming you. For the same reason, the internals of the dry sealed regulators require less regular maintenance, though you should always spend a bit of time cleaning your gear properly after every dive.

‘Medium Pressure’ Ports

Apeks use the term ‘Medium Pressure’ to describe intermediate pressure or low pressure ports. This is a historical throwback, but they’re exactly the same.

Reversible Design

Apeks XTX range of regulators are reversible allowing you to route your hoses from either the right or left side of the second stage to suit your preference. Similarly, the venturi switch and exhaust is also reversible.

Diver Changeable Exhaust System.

XTX regulators feature the Diver Changeable Exhaust (DCE) system which offers users the choice of either a compact, light-weight exhaust tee on the second stage or a wider exhaust. The wider exhaust prevents bubble interference which is ideal for underwater photographers!

The Apeks Regulator Line-Up

While you can buy both the Apeks first and second stages individually, most divers will want to purchase a full set as this offers the best value for money.

All of Apeks’ ATX, XTX and MTX regulators are environmentally sealed and overbalanced making them suitable for diving in sub 10*C conditions.

The Apeks Regulator Line-Up

All of Apeks’ ATX, XTX and MTX regulators are environmentally sealed and overbalanced making them suitable for diving in sub 10*C conditions.

Apeks ATX

  • First Stage: DS4

  • Second Stage: ATX40

Apeks entry level, sealed, cold-water regulator, the ATX offers straightforward, reliable performance that’s ready for UK diving. The ATX is sold with the ever reliable DS4 first stage. While it’s nothing flashy, it features 1 low pressure port and 4 high pressure ports which should offer enough flexibility for beginner and experienced divers alike.

The only real downside is the slightly bulky nature of the second stage and lack of adjustability that Apeks’ more expensive offerings offer.

Apeks XTX40

  • First Stage: DST

  • Second Stage  XTX40

The XTX40 steps up from where the ATX leaves off. Paired with the DST first Stage the combo delivers a tangible step-up in performance at an affordable price. The more up to date XTX40 second stage provides noticeably improved breathing over the ATX40, as well as being lighter. The DST second stage provides 2 low pressure and 4 high pressure ports with a swivel turret which provides a whole lot more flexibility. Lastly, the second stage is rated more highly for use at extreme depths than their entry level models, though in reality first stages like the DS4 are going to function equally well for most dives!


Apeks XTX50

  • First Stage: DST

  • Second Stage XTX50

The XTX50 is our recommendation for most divers as it offers the best between cost and features. The second stage is the same as the XTX40 with addition of a diver adjustable breathing resistance control which we think is worth the extra small outlay. The XTX50 + DST combo is probably Apeks’ best seller for good reason. Its dependable, high performing and feature rich, it’s everything you could ask for in a regulator without spending big bucks.

Apeks XTX100

  • First Stage: FST

  • Second Stage: XTX100

Internally, the XTX50, XTX100 and XTX200 second stages are exactly the same. However the  XTX100 + XTX200 second stages are constructed using lighter, higher quality ,materials which should make them more hard wearing in the long run. It’s not necessary, but when considering your purchase as a long term investment it might be worth thinking about.

The Apeks FST first stage is a serious bit of a kit. Not just a beautiful piece of engineering, it offers typically flawless Apeks’ performance. Angled ports provide improved routing for your hoses which can be extra handy for keeping them tamed.

Apeks XTX200

  • First Stage: FSR

  • Second Stage XTX200

The XTX second stage features the same spec as the XTX100 model, with a slightly upgraded body.

The FSR Second stage offers similar features to the FST first stage but with a removable ARCAP Valve seat which should allow you to keep using the FSR for forever and a day, if you’re looking for a no holds-barred reg the XTX200 might be the way to go.

Apeks Tungsten XTX

  • First Stage: Tungsten FSR

  • Second Stage: Tungsten XTX200

Exactly the same as the XTX200, but with a nuclear bomb-proof PVD coating made from Titanium, Zirconium and Chromium that makes the Tungsten XTX nearly indestructible. It might be a touch over the top - but if you’re looking for a beautiful piece of dive engineering that will perform flawlessly anywhere and double as an art piece when you’re out of the water...get the Tungsten XTX.

Apeks MTX-R

  • First Stage: MTX-R

  • Second Stage: MTX-R

Based on the Apeks’ military grade MTX regulator, the MTX R is an incredible piece of engineering. We’ll be honest, for most of you this level of tech simply isn’t necessary. However, if you’re looking for the toughest regulator on the market that shrugs off near zero degrees condition there simply aren’t any options that even get near the MTX-R.

Apeks XL4

  • First Stage: XL4

  • Second Stage: DB4

The XL4 is the bridge between Apeks super-light ‘Flight’ travel reg and their best-selling XTX series regs. Tough as a tank, cold-water ready and comfortably light, the XL4 is remarkably good and has been cutting a fine figure, receiving top marks across the board from a host of reviewers and we think if you can afford it, it should be the go-to regulator if you dive a variety of environments and like to travel!

Warm Water & Travel Regulators Regulators

Unlike the rest of Apeks’ range which are designed to laugh off the harshest conditions, their warm water regulators are designed for more pleasant climes - while this might make them less than ideal for diving off the coast of Scotland, these regulators offer their own advantages - we’ve separated them from Apeks’ mainstream options for this reason.

Apeks Flight

  • First Stage: Flight

  • Second Stage: Flight

When the Flight was released to the world it was the lightest regulator on the market by a serious margin and it’s still up there. The hint is in the name really: Flight. If you’re a regular jetsetter who dives in warmer climates (anything above 10*c) the Flight is a great option.

Apeks AT

  • First Stage: US4

  • Second Stage: AT

Apeks entry level offering displays the brands usual bulletproof build-quality and impressive breathing despite the asking price. While it’s neither feature rich nor suitable for cold water diving, but if you’re on a budget and dive in pleasant conditions, it's still a great place to start for a beginner.
