The Perdix 2 Ti Silver is Shearwater’s toughest and most reliable full-size computer yet. The armoured casing with precision titanium surround bezel and dependable titanium piezo touch buttons protect performance-enhanced electronics. This air integrated multi gas dive computer is capable of connecting up to 4 transmitters.
An aluminosilicate glass lens guards a fantastic 2.2” bright screen and offers improved clarity, impact, and damage resistance. A strong vibration customisable alert system draws attention at critical moments of the dive.
Air integration with up to 4 optional Shearwater transmitters allows room to grow from a first computer to a powerful, proven advanced technical diving solution. This is delivered using the trusted and easy to find user-changeable single AA battery and familiar ergonomic compact form factor.
Available in two colour finishes: Shearwater Perdix 2 Ti and Perdix Ti Black colour finishes.

Optional Air Intergation
With smart AI technology, the Swift creates a highly reliable connection, listens for other transmitters, and only communicates when the channel is clear by avoiding collision with other signals. Now, divers can use multiple transmitters near each other without worrying about potential interference.
This advanced technology is leveraged by Shearwater's new firmware which includes support for up to 4 transmitters on compatible Shearwater models.
The no-tools design makes it easy to remove and replace the Swift from the 1st stage (gone is the need to find a particular size tool to tighten or loosen the transmitter, making it perfect for travel!)
A double o-ring seal protects a user-replaceable 3v CR2 lithium battery offering up to 300 hours of time. The LED status indicator lets the diver know things are functioning as they should at a glance during setup.
High Resolution, easy-to-read display
2.2" display with vivid, enhanced colour range and saturation. Impact resistant toughened aluminosilicate glass screen with superior clarity.
Thin, Low-profile Design
30% smaller in volume than the Petrel 2.

Download and display dive logs quickly with Bluetooth® wireless technology. You can display as much or as little information as you need. The Shearwater cloud is available in 13 languages.
The Perdix AI comes with Bühlmann ZHL-16C algorithm with Gradient Factors installed but you can upgrade it to VPM-B with a special PIN, giving you the option of using the standard GF deco or switching to VPM-B. Once you select this option we will organised to the unlock code for your specific model and serial number. You will then need to update your firmware to the latest firmware before using the PIN code.
VPM or the Varying Permeability Model is a decompression algorithm that attempts to model the behavior of bubbles within the human body during decompression. The algorithm was initially developed by David Yount in laboratory testing and coded into Fortran by Erik Baker.
Shearwater Research has implemented VPM-B according to the original Erik Baker Fortran specification. In addition to implementing the Baker model, Shearwater Research has added a new option. VPM-B dive profiles often have deep stops to control bubble formation with reduced time at shallow depths. The reduced shallow depth time can be quite aggressive with VPM-B so Shearwater Research has included a VPM-B Gradient Factor Surfacing (GFS) option. VPM-B/GFS allows VPM-B dives to be executed while ensuring that a gradient factor of 90% is never violated.
