Shearwater Perdix 3: what was announced
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 divers comparing the announced features, the central questions are practical: how the display presents information, which transmitter configurations it supports, and how settings can be changed. The report addresses those design intentions, but it does not document how a diver found the controls or screen underwater.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
A 6.1 cm AMOLED display
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
The reason to care about the display is straightforward: it is where the diver reads information during the dive. Size, brightness and resolution are separate parts of that presentation, and the announcement highlights all of them.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
Resolution of 450 x 600 pixels
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
The stated pixel count is a concrete specification. Whether that display is easier for an individual diver to read in a particular environment is a different question, one the announcement does not answer with comparative test results.1
Titanium construction and an armored case
The Perdix 3 is described as a computer engineered for demanding dive conditions, with precision titanium construction and an armored casing.1
According to the source, the armored 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 authorized service when needed.1
Glass protection for the display
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
The lens claim addresses a familiar equipment concern: contact with boats, cylinders, accessories and hard surfaces. The announcement pairs protection with visual clarity, presenting the screen cover as part of the computer’s construction rather than only a display feature.1
The report gives the lens material and its intended benefits. It provides no impact-test results, so the wording should remain a claim about the design, with use and care governed by the manufacturer’s instructions.1
Air integration with four 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
The Perdix 3 is presented for both recreational divers and more advanced configurations. Four-transmitter support describes what the announcement says it can accommodate; it does not determine the training a particular dive requires.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
Updated menus and 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
What the announcement means for divers
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
