Merging state of the art manufacturing techniques, innovative engineered materials, and consumer feedback, SHEARWATER has successfully developed a low-profile, sleekly contoured design without sacrificing features vital to technical divers. It’s everything you love about the Petrel dive computer, just smaller.

The PERDIX has 4 different dive modes:

OPEN CIRCUIT RECREATIONAL: in this mode the PERDIX works like a full-featured nitrox computer and is able to handle 3 different gases. The perfect mode for the serious recreational diving enthusiast. Includes adaptive safety stop and NDL bar graph.

OPEN CIRCUIT TECHNICAL: in this mode the PERDIX can handle 5 gases and is Trimix enabled by default.

CLOSED CIRCUIT/BAILOUT: handles 5 OC/5 CC gases, Trimix enabled, constant PO2 for closed circuit.

GAUGE: depth, time, resettable stop watch function, full dive logging.

A 2.2" big display let's you customise which information you want to see on the display. Find your way with the integrated 3 axis, tilt compensated digital compass. The PERDIX can be set to different languages including French, Spanish and many more. Download dive details and log using Bluetooth technology.

Our personal note: we all love it! You don't need to be a rebreather diver or super serious tech-diver to appreciate this computer. If you want just a bit more or plan to do technical diving in the future the PERDIX is a great investment. It is a bit smaller due to its contoured shaped, lighter and more economic on the battery use than the PETREL.

We recommend to use all dive computers conservatively and follow DIVERS ALERT NETWORK’s tips for a safer use of dive computers!

    • Intuitive Interface: The Perdix 2's display is user-friendly and easy to read, even in low visibility underwater conditions. Divers can quickly access essential information such as depth, remaining dive time, water temperature, and more.
    • Multiple Gas Capabilities: The Shearwater Perdix 2 supports diving with various gas mixes, making it an ideal choice for divers who use nitrox, trimix, or other gas blends for more complex and advanced dives.
    • Advanced Decompression Algorithms: The dive computer's decompression algorithms are based on sophisticated calculation models that help divers plan and execute dives safely. These algorithms aid in preventing the formation of nitrogen bubbles in the body, reducing the risk of decompression sickness.
    • Comprehensive Dive Logging: The Perdix 2 automatically records data from each dive, including maximum depth reached, dive duration, water temperature, and gas blends used. Divers can transfer this data to their computer or compatible device for detailed analysis of their diving experiences.
    • Customization: The Shearwater Perdix 2 allows divers to personalize the display screens and settings according to their preferences. They can choose the information they want to see during the dive and adjust settings to match their diving needs and style.
    • Wireless Connectivity: Some versions of the Perdix 2 come equipped with wireless connectivity features, enabling divers to transfer dive data to mobile devices or compatible apps. This facilitates data sharing with other divers, data backup, and more in-depth analysis of their diving performance.
