Apeks Dive Computers — Built for Divers Who Demand More
Apeks entered the dive computer market with a clear brief: build an instrument worthy of the same reputation as their regulators. The result is the DSX — a full-featured technical dive computer developed in partnership with Pelagic, specialists in dive computer technology and the same team behind the Aqualung i770R. The DSX is designed from the ground up for technical divers, but its versatility and straightforward interface make it a genuinely useful tool for any diver who wants a serious, long-lasting instrument.
At DiveCatalog.com, we carry the Apeks DSX dive computer and the Apeks wireless transmitter, which pairs with the DSX for real-time tank pressure monitoring. Together they form one of the most capable wrist-based dive computer systems available at this price point.
The Apeks DSX — Feature Breakdown
Algorithm and Gas Support
The DSX runs the Bühlmann ZHL-16C decompression algorithm with user-configurable gradient factors — the same algorithm trusted by technical divers worldwide, with the flexibility to adjust conservatism to suit your diving style and training. It supports air, nitrox (up to 100% O2), and trimix, and can manage up to six different gas mixes simultaneously. This makes it fully capable of multi-gas technical dives, sidemount configurations with separate cylinders, and stage decompression profiles.
Dive Modes
The DSX supports open-circuit sport and technical modes, closed-circuit rebreather (CCR) mode with constant setpoint, sidemount mode with gas-switch notification, and gauge mode. This range covers recreational through to advanced technical diving in a single instrument.
Air Integration
Wireless air integration via up to six simultaneous transmitters means sidemount divers and multi-cylinder technical divers can monitor tank pressure across all their cylinders from one screen. The Apeks Transmitter (sold separately) is O2-cleaned and compatible with the DSX.
Display and Navigation
The DSX features a 2.4-inch colour TFT LCD display — bold characters and customisable graphics make critical data readable in low visibility and at depth. An ambient light sensor adjusts brightness automatically. Three stainless steel buttons navigate the menus, and the display can be flipped for either orientation. Divers can save up to 10 images directly to the computer — useful for dive slates, maps, and decompression schedules.
GPS and Navigation
Surface GPS logs entry and exit points for each dive, and a waypoint function allows you to set a target and navigate back to it using return heading and distance — practical for boat diving, drift diving, and expedition work.
Connectivity and Charging
Bluetooth 5.0 connects the DSX to the DiverLog+ app for wireless dive log syncing, settings management, and firmware updates. The computer supports both induction (wireless) charging via the included charging mat and traditional cable charging. Operating time reaches approximately 80 hours on a full charge.
Build Quality
The outer bezel is titanium — lightweight and extremely durable. The case is impact-resistant engineered polymer with a high-impact PU trim and integrated screen protector. Two mounting options are included: dual elastic straps with slide-release buckles, and a bungee attachment. The DSX also ships with an oxygen analyser module (an R-22 sensor, sold separately, is required to use the analyser function).
Depth Rating
The DSX is rated to 150m — well beyond the limits of recreational and most technical diving applications.

How to Choose: DSX vs. Other Computers
The DSX competes at the high end of the technical dive computer market. Its key differentiators are the integrated oxygen analyser, GPS functionality, six-transmitter air integration, and CCR/sidemount modes — features that most recreational dive computers simply don't offer. If you dive with a single cylinder in warm water and don't need gas switching or technical modes, a simpler computer may suit you better and save money. But if you're already diving nitrox, planning to move to technical diving, or diving sidemount or CCR, the DSX is a future-proof investment that won't need replacing as your diving advances.
The key difference between the DSX and recreational computers is the gradient factor control on the decompression algorithm — this lets you tune how the computer handles decompression stops, which matters significantly for technical and deep diving. Most consumer dive computers don't offer this level of control.

Frequently Asked Questions — Apeks Dive Computers
Is the Apeks DSX suitable for recreational diving?
Yes, though it's engineered primarily for technical divers. The intuitive 3-button interface and colour display make it easy to use for recreational diving, and nitrox support is standard. Many recreational divers choose the DSX because it won't limit them if they progress to technical training.
Does the DSX support trimix?
Yes. The DSX fully supports trimix diving and can manage up to six gas mixes simultaneously — making it suitable for deep technical decompression dives.
How does the air integration work?
The DSX pairs wirelessly with up to six Apeks transmitters simultaneously. Each transmitter attaches to a first stage high-pressure port and sends real-time tank pressure data to the computer. This is particularly useful for sidemount divers monitoring two separate cylinders, or technical divers managing stage and back-gas bottles.
What is the Bühlmann ZHL-16C algorithm?
The Bühlmann ZHL-16C is a widely used mathematical model for calculating decompression obligations during a dive. The "gradient factors" adjustment on the DSX lets experienced divers modify how conservatively the algorithm schedules decompression stops — a feature valued by technical divers who understand decompression theory and want more control over their dive profiles.
Does the DSX have a compass?
Yes. The DSX includes a 3D digital compass for underwater navigation, in addition to the surface GPS functionality for logging dive sites and waypoints.
How is the DSX charged?
The DSX supports both wireless induction charging via the included Qi-compatible charging mat, and traditional USB cable charging. Wireless charging is convenient for travel; cable charging is faster. Battery life reaches approximately 80 hours of operating time.
Is the oxygen analyser included?
The DSX ships with the analyser module accessory, but requires a separate R-22 type sensor to function. The sensor is not included in the base package — contact us for details on compatible sensors.
Can I update the firmware on the DSX?
Yes. Firmware updates are delivered wirelessly via the DiverLog+ app using Bluetooth 5.0. Apeks actively supports the DSX with firmware updates.
The Apeks DSX is one of the most capable wrist-mounted dive computers on the market, and the Apeks transmitter makes air integration clean and straightforward. Browse the collection above or contact our team if you'd like help deciding whether the DSX is the right instrument for your diving.
