Shearwater Perdix 3 AMOLED Dive Computer

What divers should know before getting in the water

According to DIVE Magazine, Shearwater Research announced the Perdix 3 on May 20, 2026, describing it as the company’s toughest and most capable full-size dive computer to date.¹

The announcement focuses on the screen, construction, durability, air integration and user interface, rather than on an independent in-water review of the product.¹

For scuba divers, this news matters because it shows where dive computers are moving: better visibility, broader support for different dive configurations, and quicker access to information during the dive.¹

The details are worth reading carefully, because the source reports an announcement and manufacturer claims, not practical testing from dives with the model.¹

The Perdix 3 has a 6.1 cm (2.4 inch) AMOLED display with ultra-high brightness

The Perdix 3 has a 6.1 cm display, equal to 2.4 inches, and the source describes it as an ultra-bright AMOLED display.¹

Shearwater says the screen is intended to deliver visibility, reliability and versatility for divers at different levels and in different dive environments.¹

In a dive computer, screen readability is central to the experience, because the information on the display follows the diver in real time underwater.¹

The source says the larger and brighter screen is designed to improve readability in bright surface intervals as well as in deep dives or low-visibility dives.¹

The Perdix 3 screen resolution is 450 x 600 pixels, four times higher than previous models

The Perdix 3 screen resolution is 450 x 600 pixels, a figure the source describes as four times higher than previous models.¹

According to the report, the combination of higher resolution with a larger and brighter display is designed to significantly improve readability in different lighting conditions.¹

For a diver, the practical meaning is the potential for a screen that is easier to read as conditions change, but the source does not present independent measurements or an in-water comparison with other models.¹

It is therefore better to treat this figure as part of the new model presentation, not as a final conclusion about screen performance at every dive site or in every visibility condition.¹

The Perdix 3 is built from titanium with an armoured case to protect the electronics

The Perdix 3 is described as a computer engineered for demanding dive conditions, with precision titanium construction and an armoured casing.¹

According to the source, the armoured casing is designed to protect the computer’s performance-enhanced electronics at depth.¹

The use of titanium and a tough case fits the way Shearwater presents the model: a full-size dive computer aimed at durability, advanced functionality and user-focused design.¹

The source does not include care, opening, repair or maintenance instructions for the model, so any such action should rely on the manufacturer’s instructions for the exact model and on authorised service when needed.¹

The screen is protected by a toughened aluminosilicate glass lens for impact resistance

The Perdix 3 screen is protected by a toughened aluminosilicate glass lens, according to the details published in the report.¹

Shearwater claims the lens provides strong visual clarity and impact resistance.¹

This is an important detail in the model presentation, because a dive computer is a piece of equipment used in an environment where gear can touch boats, cylinders, accessories and hard surfaces.¹

Here too, the detail describes the protective structure of the Perdix 3, but it does not replace personal suitability checks or use according to the manufacturer’s instructions.¹

The Perdix 3 supports air integration with up to four Shearwater transmitters

The Perdix 3 supports air integration with up to four Shearwater transmitters.¹

According to the source, that support allows the model to scale from a recreational diver’s first air-integrated computer to a more advanced system for a technical multi-gas setup.¹

This detail positions the Perdix 3 as a computer intended to cover a wide range of needs, from recreational diving to more advanced configurations.¹

Even so, using multi-gas, transmitters and advanced configurations requires suitable training and familiarity with the equipment, and the source does not provide training instructions for that kind of use.¹

The Perdix 3 has an updated user interface with intuitive menus and programmable quick-change settings

The Perdix 3 introduces an updated user interface with intuitive menu navigation, according to the report on the announcement.¹

The source says the interface is intended to allow divers to access critical information quickly and confidently.¹

The model also adds programmable quick-change settings, designed to make it easier to switch between custom layouts and different dive configurations.¹

That capability is presented as especially relevant for divers who move between different dive types or conditions, but the source does not describe full use scenarios or operating instructions.¹

Safety and responsibility in the water

The Perdix 3 is presented as an advanced dive computer, but the source does not present it as a replacement for training, dive planning or understanding the limits of the diver and the equipment.¹

A bright screen, high resolution and air integration can make information more accessible, but the diver still has to interpret that information within their training and planned dive.¹

When settings, configurations, transmitters or advanced uses are involved, it is right to follow the manufacturer’s instructions for the model and the relevant training framework.¹

An announcement of new equipment is a good opportunity to understand the direction of the technology, but a decision to use or buy it should also rest on personal fit, service, instruction and experience in the water.¹
