FAQ – Shearwater Perdix 3

Q: Is the Perdix 3 suitable for recreational diving?

Yes. While built with technical capabilities, many recreational divers choose the Perdix 3 for its unparalleled readability, rugged durability, and long-term flexibility. It features a simplified "OC Rec" mode that strips away technical clutter, expanding only when your training does.

Q: Do I need air integration?

Air integration is completely optional. Some divers prefer a classic, non-integrated setup, while others value seeing live tank pressure and gas-time-remaining (GTR) metrics directly on their wrist. The choice is yours, and our team can help configure the Perdix 3 to match your specific rig.

Q: Can the Perdix 3 be used for Trimix and advanced decompression?

Yes. The computer fully supports multi-gas Trimix and advanced decompression planning out of the box. Simply switch the device to "OC Tec" or "CC/BO" mode to unlock its advanced technical features under appropriate training and safety procedures.
