Why Suunto dive computers stand out
Suunto has been building dive computers for decades, and their reputation for reliability, precision, and bold display design is well earned. Every model in this sale is manufactured in Finland using 100% renewable, carbon-free energy — so choosing a Suunto is a choice that's good for your diving and the planet. All three models on sale share a few brilliant traits:
- Rechargeable lithium-ion batteries via USB — no more hunting for CR2 cells on a liveaboard
- Bluetooth connectivity for wireless dive log transfer and firmware updates via the Suunto app
- Wireless tank pressure monitoring with Suunto Tank PODs
- Suunto's trusted Fused RGBM or Fused RGBM 2 decompression model for accurate, conservative dive planning
Now, let's break down each model so you can make the best call for your diving.
Suunto dive computers in this sale
Suunto EON Core
Best for: Recreational divers heading towards technical diving who want a lighter wrist computer with a brilliant display and room to grow.
The EON Core is the smart middle ground in Suunto's range — smaller and lighter than the EON Steel but with a feature list that punches well above its compact composite housing. Rated to 80m and weighing just 154g, it's comfortable on the wrist for divers in thin wetsuits or rash guards, with three side-mounted push buttons that feel natural underwater.
The full-colour LED-backlit TFT display is a real highlight — 320 x 240px with auto-rotate and a 3D tilt-compensating compass built in. You get four customisable screen modes with large, easy-to-read digits, and the screen colour-codes your dive data so priority alerts are never missed at depth. Charging is simple from any USB port, and a full battery gives 10–20 hours of dive time.
Dive modes supported:
- Air, Nitrox, Gauge, Trimix, and CCR (fixed point, activated via DM5)
- Up to 10 Suunto Tank PODs paired simultaneously
- Wireless Bluetooth sync via Suunto Movescount app
Suunto EON Steel Black
Best for: Technical divers, advanced recreational divers, and anyone who wants a future-proof computer that can handle any dive they'll ever do.
If you want the best Suunto dive computers have to offer in a single wrist-mounted unit, the EON Steel Black is it. The headline upgrade over the original EON Steel is the addition of a second algorithm — you now get both Suunto Fused RGBM 2 and Bühlmann ZHL-16 with Gradient Factors, letting you dial in your decompression profile to suit your team, your dive plan, and your personal conservatism setting.
The brushed stainless steel bezel looks as serious as it performs, and the high-contrast display is readable in the murkiest visibility. A 40-hour battery life means the EON Steel Black will outlast even the most ambitious liveaboard schedule. It's pressure-rated to 150m and tested in real diving conditions by Suunto's in-house dive team.
Full customisation is handled via the Suunto app — build and save your own dive modes, set gas preferences, configure alarm thresholds, and choose your algorithm per dive. Up to 20 Tank PODs can be paired, making it ideal for technical diving with multiple cylinders. The computer ships with a hard case for safe storage between dives.
Suunto D5
Best for: Divers who want a dive computer they can wear every day, travel divers who need a compact and stylish option, and anyone upgrading from a basic console computer.
The D5 is Suunto's watch-style dive computer — the slimmest and most wearable of the three, weighing just 90g with quick-release exchangeable straps that let you match it to your kit or wear it as an everyday watch. It's depth-rated to 100m and features a bright full-colour MIP display with LED backlight, vibration and sound alarms for important alerts, and mineral crystal glass for durability.
Connectivity is via Bluetooth for dive profile download and firmware updates, and up to three wireless Tank PODs can be paired for on-screen pressure display and air time remaining. The D5 uses Suunto Fused RGBM 2 — the same trusted algorithm as the EON Steel — and supports Air, Nitrox, Freedive, and Gauge modes with up to three gas mixes.
The rechargeable battery is a real travel advantage, and the DM5 USB interface is included in the box for computer connection.

FAQs
Do all three Suunto dive computers support wireless air integration?
Yes — all three models support wireless tank pressure monitoring via Suunto Tank PODs. The D5 supports up to 3 pods, the EON Core up to 10, and the EON Steel Black up to 20.
Can I use these computers for freediving?
The Suunto D5 includes a dedicated Freedive mode. The EON Core and EON Steel Black are focused on scuba diving modes including Gauge, which can be used as a depth/time instrument during freediving, but neither has a dedicated apnoea algorithm.
Are Suunto dive computers good for beginners?
Absolutely. The D5 and EON Core in particular are very intuitive with large colour-coded displays and simple button navigation. Both are excellent first dive computers that grow with you as your diving develops.
How do I update the software on my Suunto dive computer?
All three models support user-updatable firmware. Updates can be applied via the Suunto app over Bluetooth, or via Suunto DM5 software on PC or Mac using the included USB cable. Keeping firmware current is always recommended for the latest features and safety improvements.
Is Bühlmann ZHL-16 safer than Suunto Fused RGBM?
Neither is universally "safer" — they're different approaches. Bühlmann with Gradient Factors offers more customisable conservatism and is preferred by many technical divers. Fused RGBM 2 uses a probabilistic approach that accounts for repetitive dives and fatigue. The EON Steel Black gives you both, which is a genuine advantage for teams using mixed computers.
These price drops won't last forever — and with three genuinely excellent Suunto dive computers on offer, now is the perfect moment to upgrade your wrist game. Whether you're heading to the Red Sea next month, planning your technical diving progression, or just want to replace that ageing console, there's a Suunto in this sale for you.
