    Apeks is a British dive-gear maker with a long following among technical and cold-water divers, and its regulators, fins and tech accessories are available in Singapore through Dive Singapore at 178 Paya Lebar Road #03-03. If you are building a serious, travel-ready or entry-technical setup, the core Apeks range here runs from the compact XL4+ first-and-second stage at S$755 up to the military-derived MTX-RC at S$1,095, with the popular RK3 spring-strap fins at S$350.

    Why Apeks has such a loyal following

    Apeks built its reputation on regulators that keep breathing smoothly in the conditions most brands struggle with: deep, cold and heavily loaded with gas demand. The company originated its designs in the United Kingdom, and several of its products trace back to military and special-forces briefs. That heritage is why you see Apeks so often on twinsets, sidemount rigs and deco stages rather than only on holiday rental racks.

    For divers in Singapore, the appeal is a little different. Local training dives at Pulau Hantu and Lazarus Island sit in warm tropical water, so the cold-water sealing is not strictly necessary at home. It still matters for two reasons. First, the same sealed first stages that resist ice also keep silt and grit out of the internals, which suits our sediment-heavy Southern Islands. Second, many local divers travel to cooler destinations, and a regulator that is genuinely cold-water rated means one setup covers both trips.

    Apeks regulators available in Singapore

    The regulator line is where Apeks earns its name, and the range stocked locally covers everything from a light travel rig to a full technical setup. The XTX 50 second stage pairs with the DST first stage, which uses an over-balanced diaphragm so medium-pressure gas keeps rising faster than ambient pressure as you descend. In plain terms, that means the regulator holds its breathing performance at depth. The XL4+ is the lighter, more compact option, while the MTX-RC sits at the top for demanding cold and technical work.

    Model Price First stage character Best suited to
    Apeks XL4+ S$755 Compact, cold-water sealed diaphragm Travel and everyday recreational diving
    Apeks XTX 50 S$880 DST over-balanced diaphragm All-round recreational into entry technical
    Apeks XTX 50 with 5th Port Turret S$945 DST with extra fifth port on the turret Twinset and sidemount hose routing
    Apeks XTX Tungsten S$1,165 XTX build with tungsten finish Divers wanting a premium, hard-wearing look
    Apeks MTX-RC S$1,095 Military-derived, extreme-condition design Serious cold-water and technical diving

    If you are building a custom or stage regulator around a known second stage, the Apeks DST First Stage is sold on its own at S$485. That is the same over-balanced first stage under the XTX 50, so it is a sensible building block for a second cylinder or a deco setup where you want matched parts across your rig.

    The MTX-RC deserves a note for the technically minded. Its design brief came from a test where a regulator has to keep flowing freely in near-freezing water at sixty metres under a very high gas demand. The “RC” points to the adjustable second stage, which lets you tune breathing resistance and switch the venturi to suit the phase of your dive. That level of control is overkill for a warm-water fun dive, but it is exactly what a technical diver wants when the workload climbs.

    Apeks fins: RK3, RK3 HD and RK4

    The RK3 is arguably as famous as any Apeks regulator. The blade design goes back roughly half a century to United States Navy special-warfare use and has been recreated in the UK as a modern technical fin. It is a short, wide paddle built from tough thermoplastic rubber, with a vented strip across the blade and oversized foot pockets sized to swallow drysuit boots or rock boots.

    All of these ship set up for stainless-steel spring straps, which are the standard choice for technical and drysuit divers because they never need adjusting and go on quickly with cold or gloved hands. For local warm-water use the RK3 is a firm favourite among divers who want precise trim and clean, silt-friendly kicking around wrecks and reef at the Southern Islands.

    Apeks tech gear beyond regulators

    Apeks is not only regulators and fins. The brand also makes utility pieces aimed at the technical diver. In the local catalogue you will find the Apeks Tech Shorts at S$450, a rugged over-short worn on top of a wetsuit or drysuit to carry and protect the small tools, spools and pouches a technical diver clips on. It is a good example of the purpose-built kit that rounds out an Apeks setup once your regulator and fins are sorted.

    How to choose the right Apeks setup for local diving

    Start from the diving you actually do, not the specification sheet. Most divers based in Singapore are doing warm-water recreational trips with occasional travel, so the decision usually comes down to weight, budget and how far you plan to push into technical diving.

    1. Warm-water recreational and travel: the XL4+ is compact and light, which is easy on baggage allowances and plenty of regulator for reef and wreck diving.
    2. All-round with room to grow: the XTX 50 gives you the proven DST first stage and an adjustable feel, a natural pick if you might take up technical training later.
    3. Twinset or sidemount: the XTX 50 with the fifth-port turret makes hose routing cleaner for redundant setups.
    4. Serious cold and technical work: the MTX-RC is the specialist tool for demanding conditions and heavy gas loads.

    If you are still early in your diving and unsure how far you will go, it is worth completing your core certifications first so you understand your own preferences. Dive Singapore runs PADI Open Water, Advanced and Rescue at a flat S$838 in small classes of four to five students, which is a sensible way to log real dives before committing to a full kit.

    Buying and servicing Apeks in Singapore

    Buying from a local dive shop rather than an overseas site has real advantages with a regulator, because a regulator is a life-support item that needs periodic servicing. A local purchase means you have somewhere to bring it, someone who knows the model, and access to genuine spares. Dive Singapore stocks the Apeks range at 178 Paya Lebar Road #03-03 and can advise on the setup that matches your certification level and travel plans.

    Before you buy, it is worth doing three things:

    Frequently asked questions

    Is Apeks worth it for warm-water diving in Singapore?

    Yes, although you will not use every feature at home. Apeks regulators are built to keep breathing smoothly in cold and demanding conditions, and the same sealing that fights ice also keeps silt out of the internals, which suits our sediment-rich Southern Islands. The bigger payoff comes if you travel to cooler sites or move into technical diving, where one Apeks setup covers both.

    Which Apeks regulator should a new diver buy?

    For most newer divers the XL4+ at S$755 or the XTX 50 at S$880 make the most sense. The XL4+ is lighter and travel-friendly, while the XTX 50 uses the DST first stage and an adjustable second stage that leaves room to grow into technical diving. The MTX-RC is excellent but aimed at serious cold-water and technical use.

    What is the difference between the RK3 and RK3 HD fins?

    Both are the same short, wide paddle design at S$350. The RK3 HD is made from a higher-density material, which makes it stiffer, heavier and more negatively buoyant. That extra weight is welcome for wetsuit diving and helps hold good trim, while the standard RK3 is a touch lighter in feel.

    Do Apeks fins come with spring straps?

    The RK3, RK3 HD and RK4 are all set up for stainless-steel spring straps, which is the standard choice for technical and drysuit divers. Spring straps never need adjusting, they go on quickly with cold or gloved hands, and their oversized foot pockets fit both drysuit boots and rock boots.

    Where can I buy and service Apeks gear in Singapore?

    Dive Singapore stocks the Apeks regulator, fin and tech range at 178 Paya Lebar Road #03-03, Singapore 409030. Buying locally means genuine spares, model-specific advice and somewhere to bring your regulator for periodic servicing, which matters because a regulator is a life-support item.
