Instructions for connecting your Perdix 3 to your mobile device via Bluetooth for the first time.
Pair the Perdix 3 to Dive Shearwater
Open Dive Shearwater app on your mobile device, select "Connect" from bottom menu, then select "Add Device". On Perdix 3, toggle to Bluetooth menu, ensure Bluetooth is enabled (shows "On"), then select "New Pairing".
Connect in the app
Once the countdown starts on the Perdix 3, you should see it appear in the app, select "Connect".
Confirm Codes Match
You will see codes appear in both the app and dive computer, confirm they match, then press "Pair" in the app, and "Connect" in the dive computer.
You are now Connected
A pop-up will appear in the app asking if you want to enable auto-download dive logs. On the dive computer, the status will show as connected, and the Bluetooth logo on the home screen will be blue. Once paired, it will connect automatically whenever in range.
FAQ
Still have questions? We have the answers.
The Perdix 3 has three different screen layouts available in every dive mode: Big, Standard and Tec. The Big screen layout provides the largest font size for the easiest viewing experience. Learn more.
The standard decompression model is Bühlmann ZHL-16C with Gradient Factors. Other algorithms such as DCIEM may become available in the future.
No. The Perdix 3 comes with a powerful customizable vibration alert system which is more effective than sound.
No. There is only an Air Integrated version of the Perdix 3.
Yes. The Perdix 3 will work with legacy transmitters.
No, the Perdix 3 is a stand alone only product. The Perdix 3 does have a rebreather (CC/BO) mode that uses internal fixed PPO2 setpoints. This is useful for calculating backup decompression schedules when diving a closed circuit rebreather. The Petrel 3 is sold in the Fischer and DiveCAN models for connecting to a rebreather.
We strongly recommend that if you are not diving your Shearwater computer for an extended period of time, that you remove the battery to avoid the leaks and damage that can happen in any electronic device. Your dives and data are securely stored on the computer, even when the battery is removed.
If only storing for a short period of time, we recommend to leave 1.5V Lithium batteries in the device, to keep a better estimate of remaining capacity. 1.5V Alkaline batteries should always be removed due to high risk of leakage.
Shearwater recommends service of your dive computer every 2 years by an authorized service centre.
While almost any kind of AA battery will work with your Shearwater Perdix 3, 1.5V lithium batteries like the Energizer Ultimate Lithium work best. This battery type performs well in a wide temperature range and is much less likely to leak and cause damage to your dive computer.

Shearwater does not offer VPM-B unlock codes on newer computers such as Perdix 3 because these products are standardized around Bühlmann ZHL-16C with Gradient Factors. Bühlmann GF is the modern, transparent, widely supported decompression framework used across current Shearwater products, and it gives divers controllable settings for first-stop behavior and shallow-stop conservatism.
VPM-B remains a legacy model associated with older deep-stop bubble-model practice; recent decompression research and expert guidance have increasingly questioned the benefit of deep-stop profiles, and commercial-algorithm validation work found that Bühlmann GF can be tuned to pass proposed validation tests whereas VPM-B could not be tuned to address its too-deep first-stop behavior. For those reasons, adding VPM-B to newer products would create additional testing, support, and documentation burden without a clear evidence-based benefit for most customers.
