Shearwater Perdix 3 Dive Computer + Swift GPS Transmitter
The Shearwater Perdix 3 Dive Computer + Swift GPS Transmitter combines Shearwater’s flagship full-size dive computer with wireless air integration and automatic dive-site location logging.
Built for recreational, technical and CCR diving, the Perdix 3 features a brilliant 2.4-inch full-colour AMOLED display, an intuitive interface and a rugged design engineered for demanding dive environments. Pair it with the Swift GPS transmitter to see your cylinder pressure and gas information directly on the computer while also capturing your dive entry and exit coordinates for your Dive Shearwater log.
Whether you are exploring reefs, travelling to remote dive sites or progressing into advanced technical diving, this combination delivers visibility, powerful dive planning tools and detailed post-dive information in one system.
Why Choose the Perdix 3 + Swift GPS?
Brilliant 2.4″ AMOLED Display
The Perdix 3 uses a high-resolution 450 x 600 full-colour AMOLED screen designed for visibility underwater. Three display layouts – Standard, Big and Tec – allow you to configure the information to suit your diving style, while extensive colour customisation lets you optimise readability in different conditions.
Wireless Air Integration
The included Shearwater Swift GPS transmitter sends your cylinder pressure directly to the Perdix 3, giving you convenient access to gas-pressure information throughout your dive.
The Perdix 3 can simultaneously support up to four wireless Shearwater transmitters, making it suitable for everything from a straightforward single-cylinder setup to advanced multi-gas diving.
Automatically Record Your Dive Location
The Swift GPS adds multi-constellation GNSS technology to Shearwater’s proven wireless air integration.
Before descent and after surfacing, it can capture your entry and exit coordinates. Transfer the dive to the Dive Shearwater app and your dive location can be displayed on a map alongside your dive log. This is particularly useful for boat diving, drift diving, remote dive sites and divers who want a more complete record of their underwater adventures.
GPS positioning operates at the surface and does not function underwater.
Built for Recreational & Technical Diving
The Perdix 3 is a genuinely versatile dive computer with modes covering:
- Air
- Nitrox
- 3 Gas Nitrox
- OC Tec – multi-gas and trimix decompression diving
- CC/BO – closed-circuit fixed PPO2 with bailout
- Gauge
- Freediving
- Avelo – unlock code required
Its Bühlmann Gradient Factors algorithm, full decompression support, integrated NDL and decompression planners and trimix and CCR capabilities give divers plenty of room to progress without needing to replace their computer as their diving becomes more advanced.
Designed for Clear, Confident Diving
A three-axis tilt-compensated digital compass provides intuitive underwater navigation, while strong vibration alerts help draw your attention to important dive information.
The redesigned interface is simple to navigate, and programmable setting sets make it easier to move between different configurations. High-speed Bluetooth allows dive logs and firmware updates to be transferred through the Shearwater ecosystem.
Rugged Shearwater Construction
The Perdix 3 is built around a tough armoured casing with a precision-engineered titanium bezel, titanium piezo-electric buttons and toughened aluminosilicate glass protecting the AMOLED display.
With a depth rating of 260 metres / 850 feet, it is built for divers who expect their equipment to perform in demanding conditions.
User-Replaceable AA Battery
One of the Perdix series’ most practical features remains its user-replaceable AA battery.
There is no proprietary charging cable to rely on, making replacement batteries easy to source when travelling or diving in remote locations. Battery life varies depending on battery chemistry, with the recommended 1.5V lithium AA providing up to approximately 60 hours of operation.

- Wireless cylinder pressure monitoring

Air Integration, GPS Logging & Technical Diving Capability
For divers looking for a computer they can continue using as their experience and diving develops, the Shearwater Perdix 3 with Swift GPS is an combination. The large AMOLED screen makes important information exceptionally easy to read, while wireless gas monitoring, advanced technical diving modes and automatic entry and exit location logging give you a remarkably complete picture of every dive.
From recreational reef diving to multi-gas technical and CCR diving, the Perdix 3 + Swift GPS delivers the visibility, flexibility and reliability that have made Shearwater one of the most respected names in dive computers.
How the Features Help
- Reading the display: Colour presentation separates key data such as depth, dive time and gas information. Set brightness and the available screen layout before entering the water so the information you use is easy to find.
- Controls: The listed button layout provides access to settings and alternative views. Practise navigation with your normal gloves and exposure equipment before diving.
- Navigation: A digital compass brings heading information to the same instrument as your dive data. Calibrate it as instructed and practise the available bearing and reciprocal-heading functions on the surface.
- Cylinder-pressure information: With the specified compatible transmitter, the computer shows cylinder-pressure data at your wrist. Pair each transmitter to its correct gas and check the surface reading; gas-time estimates support your existing gas plan.
- Keeping your dive record: The supported connection transfers dive logs for post-dive review and, where supported, software updates. Optional external interfaces remain separate accessories unless included in this package.
- Replaceable battery: The stated user-replaceable battery can be changed using the model’s prescribed procedure. Battery type, seals, tools and data-retention steps are specific to that computer.
- Freediving records: The applicable freediving mode records breath-hold dive and surface information separately from scuba operation. Configure prompts for your training plan and follow the manual’s restrictions on changing between modes.
Choosing and Setting Up This Model
Compare the modes, gas capability, display and mounting arrangement with the diving you are trained to do. Check exactly what this listing includes, particularly transmitters, interfaces and charging accessories. Configure the computer using its own manual and confirm gases, alerts, units and battery status before diving. A depth rating describes an instrument limit and does not establish a suitable dive depth.
Gear Care and Maintenance
After every dive, rinse gently in fresh water to remove salt, chlorine and grit. Let residue soften by soaking only as the model’s manual permits, and operate buttons during rinsing only where instructed. Do not direct a high-pressure hose or compressed air at sensor openings, and never probe them with a tool.
Follow the care section of the exact Shearwater model manual for any cleaner; fresh water is the baseline cleaning method. Keep pressure-sensor openings clear by gentle rinsing, without scraping or high-pressure jets. Air dry fully in the shade before storage or charging.
Inspect the strap, attachment points, display and seals before use. Store in a cool, dry place away from direct sunlight, heaters and hot cars, with the screen protected from loose equipment. Follow the manufacturer’s battery-storage and servicing instructions.
Change batteries only using the specified cell, correct replacement seals and the manual’s procedure. Work on a clean, dry instrument, inspect sealing surfaces and follow any required pressure or leak test before diving. A compatible battery kit does not authorise opening a model that is not user-serviceable.
