The Shearwater Perdix 2 Ti Dive Computer is Shearwater’s toughest and most reliable full-size computer supporting multiple gases, Open Circuit and CCR mode and is the best dive computer in 2023 in our view.

It supersedes the original and very popular (discontinued) Shearwater Perdix computer and comes in two colour finishes: The Shearwater Perdix 2 Ti (a.k.a Silver) and the Shearwater Perdix 2 Ti Black dive computers.

Shearwater Perdix 2 Ti Dive Computer 

Shearwater research has brought a number of enhanced features to the discontinued Perdix computer with the Perdix 2: Tough, Titanium, strong vibration and ability to monitor up to 4 transmitters being the highlights of this new unit.

These improvements make it our best dive computer for 2023 as was the popular previous version Shearwater Perdix in recent years.

The armoured casing with precision titanium surround bezel and dependable titanium piezo touch buttons protect performance-enhanced electronics while 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 (you'll not miss it!) draws attention at critical moments of the dive.

Integration with up to 4 optional Shearwater Swift transmitters allows room to grow from a first computer to a powerful, proven advanced technical diving solution with multiple cylinders.

All of this is delivered using the trusted and easy to find user-changeable single AA battery and familiar ergonomic compact form factor.

As stated above, the Shearwater Perdix 2 Ti dive computer is available in two colour finishes: Shearwater Perdix 2 Ti and Perdix 2 Ti Black, the only difference between them is the colour scheme.

Optional Air Intergation of the Shearwater Perdix 2 Ti Dive Computer

Shearwater Swift TransmittersThe Perdix 2 is capable of displaying tank pressure in all modes.

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.

Shearwater Perdix 2 Ti Dive Computer Warranty

Shearwater offers a worldwide 2-year warranty on all computers. The warranty lives with the unit, not with the original purchaser. This means that whether you buy your unit from us or second-hand, the warranty will still be effective. As the warranty is linked to the computer’s unique serial number you do not need to register your computer.

Shearwater will, at its sole discretion, repair or replace defective products covered under warranty but do note, unauthorised repairs, modifications, accidental damage or negligence are not covered by the warranty.

To benefit from this manufacturer warranty you need to contact the Shearwater support team directly at or fill out the RMA form at . Should you suspect a warranty issue, do not return the unit without first obtaining an RMA - which authorises the return. You can find a list of authorised service centres at to process local warranty issues.

Upgrade your Shearwater Perdix 2 Ti Dive Computer

Optional VPM-upgrade

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 organise 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 behaviour 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.
