New releases & most recent dive computers (2026)

Comment nous évaluons le matériel et notre doctrine

Cadre d évaluation technique : Grid O1-O8 (Dive Computers). Chaque critère est noté de 0 à 5, et le score global est calculé selon une moyenne pondérée rigoureuse.

O1 : Algorithm & decompression20%

We evaluate the mathematical decompression model (such as the widely used Bühlmann ZH-L16C). A good algorithm must be transparent, allow fine gradient factor customization, and suggest safety stops adapted to real diving conditions.

O2 : Air & multi-gas20%

This criterion measures the computer's capacity to manage multiple gas mixes (Nitrox and Trimix) underwater. For advanced technical profiles or rebreather (CCR) divers, smooth gas switching in immersion is crucial to prevent errors.

O3 : Screen & ergonomics15%

Under water, every second counts. We test screen readability in dark or turbid waters, as well as button or touchscreen ergonomics, which must remain fully usable with thick diving gloves.

O4 : Autonomy & power supply15%

Nothing is more frustrating than a battery dying before a dive. We compare the durability of rechargeable batteries versus traditional ones (like AA), highly practical to replace quickly on remote trips.

O5 : Connectivity & logbook10%

We analyze the ease of transferring dive logs to the brand's mobile app. A reliable Bluetooth connection and a clear interface make it simple to monitor dive stats over the seasons.

O6 : Compass & instruments5%

This checks the accuracy of the integrated 3D digital compass. Tilt compensation is essential underwater to navigate precisely without having to hold the computer perfectly level in front of you.

O7 : Durability & max depth10%

Diving gear undergoes heavy constraints. We evaluate the assembly quality of the casing (steel, titanium, or dense polymers) and shock resistance on the boat, as well as the maximum operating depth.

O8 : Price & customer support5%

A good investment should last. We judge the overall value for money and the manufacturer's after-sales service reputation for replacement parts or periodic maintenance.

Questions fréquentes

Are newer dive computers inherently safer than older generations?▼

Decompression principles remain constant, but modern releases dramatically improve situational awareness through color-coded alerts and customizable conservatism factors.

Is magnetic induction charging practical on a liveaboard dive boat?▼

Yes, simply place the unit on its magnetic charging cradle connected via USB to a boat outlet or standard powerbank.

Is it better to buy a brand-new release or a proven clearance model?▼

Clearance models deliver outstanding value. New releases make sense when prioritizing AMOLED readability or daily smartwatch functionality.

How have wireless tank transmitters evolved recently?▼

Modern transmitters (such as Shearwater Swift or Garmin SubWave) employ collision-avoidance protocols to prevent signal crosstalk in crowded dive groups.

Does the rechargeable lithium battery degrade over time?▼

Modern lithium cells retain over 80% of their initial capacity after 500 complete charge cycles, translating to roughly a decade of regular diving.

Do touchscreen displays work reliably underwater?▼

No, capacitive touchscreens deactivate in water. All modern dive computers automatically switch to physical pushbuttons upon immersion.
