A legacy of quality in dive equipment
When you think of British dive equipment that has earned its reputation through decades of real-world performance, Apeks is a name that invariably rises to the top. Established in the early 1970s in the UK, Apeks began as a specialist manufacturer focused on creating rugged, reliable, and effective equipment for serious divers. From their early regulator designs, which quickly became favourites among cave and technical divers, through their robust buoyancy systems and accessories, Apeks products have stood the test of time in some of the most demanding underwater conditions on the planet.
What set Apeks apart in its formative years—and what still defines the brand today—was an obsessive focus on quality engineering, thoughtful design, and an unyielding commitment to reliability. While the diving industry has expanded and changed dramatically over the decades, Apeks has remained true to those core values.
Today, Apeks gear is standard issue for many technical diving operations, training agencies, and professional instructors worldwide. In Aotearoa/New Zealand—in waters ranging from subtropical to cold, nutrient-rich environments—dive instructors consistently turn to Apeks because they know the equipment will perform when it matters most.
In this review, we take a deep dive into one of Apeks’ more recent offerings in the accessories category: the Lifeline Ascend 30 metre SMB reel. Whether you’re a recreational diver looking to advance into deeper or drift diving, a technical diver needing dependable DSMB deployment, or a professional instructor teaching buoyancy control and line skills, this reel deserves your attention.

What Is the Apeks Lifeline Ascend Reel?
The Apeks Lifeline Ascend is a reel designed specifically for deploying delayed surface marker buoys (DSMBs) safely and effectively. It comes pre-spooled with 30 metres of durable line—long enough for most open water and many tech applications—and features a host of ergonomic and functional design elements that make it intuitive to use in real-world situations.
Unlike inexpensive throwaway reels that can snag, twist, or jam when you least expect it, the Ascend is built with professional-grade construction, smooth line management, and the durability you need if you’re relying on it dive after dive.

Design & Build Quality
Materials and Construction
From the moment you pick up the Apeks Ascend, the quality is evident. The body is robust yet lightweight, engineered to withstand the knocks, salt, and abrasion associated with frequent use. Apeks has chosen materials that balance strength with longevity, and every finish, nut, and attachment point feels purposeful.
Highlights include:
Robust Frame Construction – Resistant to impact and designed to endure repeated dives in both warm and cold water.
Smooth Spool Mechanism – Allows effortless pay-out and retrieval without binding, reducing frustration and risk during DSMB deployment.
High-Grip Handle – Comfortable even with thick gloves on, which is a big plus in colder climates like around Aotearoa.
Stainless-Steel Attachment Point – A secure, corrosion-resistant clip-on point for your SMB or other gear.
Every aspect of the Ascend shows Apeks’ experience in engineering functional, reliable tools. This is not a reel that looks good in a showroom—it’s built for the rigours of real diving.

Ergonomics and Ease of Use
One of the biggest frustrations with many SMB reels on the market is poor ergonomics. Small handles, clumsy thumb brakes, and awkward winding mechanisms can all make deploying your DSMB more stressful than it needs to be.
The Ascend addresses these issues head-on.
Ambidextrous Design
Whether you’re left- or right-handed, the Lifeline Ascend feels natural in your grip. This might seem like a small detail, but under real conditions—with surge, current, or cold hands—it makes a tangible difference in both comfort and confidence.
Easy-Grip Handle
The handle is intentionally large and sculpted, giving you plenty of surface area to hold onto. Dive instructors at Aotearoa Dive routinely put this to the test in cooler winter water temperatures where gloves are thick and dexterity is reduced. The feedback they give consistently highlights how the handle design reduces fumbling and lets students focus on their buoyancy and situational awareness, rather than fighting the reel.
Smooth Line Control
The spool rotates evenly, and the line feeds off without catching or snaring. When deploying a DSMB at depth, this smoothness means you can concentrate on maintaining depth and controlling your ascent rate—as you should—rather than wrestling with line.

Performance in Real-World Diving
DSMB Deployment
If there’s one core function this reel must perform, it’s DSMB deployment—and here, the Apeks Ascend excels.
Whether you’re:
Doing a standard open water dive and signalling to the surface,
Executing drift dives in strong current,
Conducting decompression stops at depth,
Or laying a shot line on a wreck or reef,
the Ascend performs predictably and confidently. The line feeds without hesitation, so you can control your buoyancy and ascent without unexpected resistance or snap-backs.
This consistent performance is one of the reasons Aotearoa dive instructors trust Apeks gear. Local waters can vary from calm to surge-ridden swells, and beginners or advanced students alike benefit from gear that behaves the same way every single time. In training scenarios, where divers are learning critical skills, reliability isn’t just convenient—it’s essential.
⸻
Durability and Longevity
If you’re buying a reel that you expect to use every weekend or as part of professional instructing, durability is crucial.
The Ascend is clearly designed with longevity in mind:
Saltwater Resistant Components – Stainless steel and corrosion-resistant finishes help prevent the wear that can plague lesser reels.
Solid Construction – No flimsy plastics or parts that feel like they’ll fail under strain.
Replaceable Line – Should you ever need to re-spool, the design makes it straightforward without specialised tools.
Divers in colder regions like the South Island’s Fiordland or the Chatham Rise regularly expose their gear to harsher conditions—low temperatures, strong winds, and nutrient-rich water. The fact that many dive shops and instructors in these regions choose Apeks gear for daily use speaks to the trusted durability of their products.
Benefits and Why Divers Love It
Here’s a breakdown of the key benefits that make the Apeks Lifeline Ascend a standout choice:
1. Professional Quality Without Over-Engineering
Some reels are too simple and fail in crucial moments. Others are over-complex with features no diver ever uses. The Ascend strikes a balance: professional performance that’s intuitive and dependable.
2. Smooth Operation
The spool spins with minimal resistance, making both deployment and retrieval feel effortless.
3. Ergonomic Design
Comfortable grip, thoughtful layout, and ambidextrous usability ensure it’s comfortable for a wide range of divers.
4. Built to Last
From materials to mechanical design, this reel is made to endure years of regular use.
5. Trusted by Instructors
Apeks gear is trusted by dive leaders and instructors—especially in training environments—because it behaves predictably and helps students focus on learning skills rather than managing gear.
6. Great Line Capacity
30 metres is enough for most open water, drift, and many technical diving needs without excess bulk.

Comparisons with Other Reels
While this review isn’t about specific competitors, it’s worth noting where the Ascend stands in comparison to common alternatives:
• Budget Reels – These are fine for occasional use, but often suffer from snagging, poor handles, or unreliable spool action. The Ascend is noticeably smoother and more robust.
• High-End Tech Reels – Some advanced tech reels offer modular accessories or very high line capacities. The Ascend isn’t about flashy extras—it’s about practical performance at a price point that most divers will find reasonable.
For most recreational divers—especially those progressing toward advanced certifications involving DSMB use—the Ascend offers a professional-grade experience without the complexity or cost of specialised tech reels.

Best Use Cases
The Apeks Lifeline Ascend reel is ideally suited for:
Recreational Diving – DSMB deployments, drift dives, and signalling.
Advanced Courses – Perfect for students learning ascent control, depth management, and line skills.
Professional Instruction – Reliable daily use for teaching and guiding.
Cold Water Diving – Works well even with thick gloves.
Travel Divers – Compact and rugged for frequent pack/unpack cycles.
⸻
Potential Limitations
No product is perfect, and the Apeks Ascend is no exception. Some things to consider:
No Built-In Line Cutter – A small blade attachment would be useful but isn’t included.
Lacks Modular Add-Ons – Some reels allow accessory attachments (lights, markers). The Ascend keeps it simple, which most divers will like, but tech-centric users may miss expansion options.
30 m is Standard – While ample for most, very deep tech dives may require additional line or a larger reel.
None of these are deal-breakers, but they’re worth noting if you expect specialised applications.
Final Verdict
After reviewing the design, performance, ergonomics, and everyday practicality of the Apeks Lifeline Ascend 30 metre reel, it’s easy to see why this reel is quickly becoming a favourite among divers of all levels—and especially among dive professionals.
Apeks has taken decades of experience building high-end regulators, buoyancy systems, and accessories and translated that same thoughtful engineering into a reel that feels dependable in every way that counts.
The Ascend isn’t flashy—it doesn’t need to be. What matters is that it:
Performs consistently
Feels good in your hands
Handles under real conditions
Lasts dive after dive
And perhaps most importantly, it earns the trust of the divers who depend on it—whether you’re teaching a novice their first DSMB deployment in the Hauraki Gulf or guiding advanced students through a drift dive off the coast of the Coromandel.
For anyone serious about diving safety, skill progression, and gear they can rely on, the Apeks Lifeline Ascend 30m reel is a top-tier choice with a proven pedigree.
