The Perdix 2 Ti Black is Shearwater’s toughest and most reliable full-size dive computer yet. The armoured casing with precision titanium surround bezel and dependable titanium piezo touch buttons protect performance-enhanced electronics.
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.
Multiple Diving Modes
Air / Nitrox / 3 GasNx
- 3 gas nitrox computer for the serious recreational diver
- User customisable display layout
- Optionally air integrated using Swift transmitters
- Trimix enabled by default
- Optionally air integrated
- Closed Circuit/Bailout
- Trimix enabled
- Constant PO2 for closed circuit
- Optionally air integrated for diluent, oxygen and bailout gases
- Depth, time, resettable stop watch function
- Full dive logging
- Tank pressure information accessible in the information screens
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.
Two Button Interface
Simple to navigate, state-aware menu structure.
User Replaceable Batteries for both Perdix 2 and Transmitter
The Perdix 2 works with any standard AA battery and the transmitter uses a 3V CR2 Lithium.
Bluetooth® Wireless Technology
This enables communication with PC, Mac, iPod, and iPad with lower power consumption.
User Customizable Display
Customize your display with information important to you.
Languages include: English, French, Simplified Chinese, Traditional Chinese, German, Portuguese, Korean, Japanese, Italian, and Spanish.
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.

What type of batteries can I use and what maintenance does it need?

While almost any kind of AA sized battery works with your Shearwater Perdix AI, the standard 1.5V alkaline battery (the type found in stores around the world) works best.
There are numerous types of AA sized batteries that will work in your Shearwater Perdix, read below for more details:
Shearwater recommends the AA 1.5V alkaline battery (e.g. the Duracell Coppertop) because it is:
- Available anywhere
- DGives about 45 hours of diving
- As an added bonus your Perdix provides a useful “Fuel Gauge” display for these batteries.
LEAKAGE WARNING: Alkaline batteries are prone to leaking, especially when completely discharged. Do not store with a discharged alkaline battery installed.
The Saft 3.6V LS14500 battery (used by the Shearwater Predator) is also a good choice, primarily because it has the longest usable life (130 hours on medium brightness). However they are:
- Hard to find
- Sensitive to temperature and storage conditions
In addition they are incompatible with the new “Fuel Gauge” feature so only three levels are given: Full, Low (Yellow) and Critical (Red).
Li-Ion - Rechargeable
The 3.7V Li-Ion 14500 battery is a good choice that can be purchased online. The AW brand is recommended and typically high quality. The brands Trustfire and Ultrafire can be good, but seem to come from a wider variety of sources and many users report getting duds. The Li-Ion batteries give about 40 hours per charge and are compatible with the new “Fuel Gauge” feature. Note that these batteries are actually about 4.2V when fully charged.
NiMH - Rechargeable
The 1.2V NiMH battery can also be used. These are commonly used in photo flashes and digital cameras, and can be purchased in most electronics stores. About 35 hours per charge can be expected. We recommend using the low self-discharge models typically labeled as “pre-charged”, “ready charged”, “stay charged” etc. and have capacities around 2000mAh. The older style high self-discharge batteries have higher capacities (around 2800mAh) but are not recommended. They will work, but will go dead in a few weeks just sitting on the shelf. Also, all NiMH batteries are incompatible with the new “Fuel Gauge” feature so only three levels are given: Full, Low (Yellow) and Critical (Red). If you have these batteries already from your photo flash, feel free to use them. However we do not recommend buying them for the Perdix as better choices are available.
Photo Lithium 1.5V
These are the best choice for cold water divers. Sold as the Energizer brand Advanced Lithium and Ultimate Lithium batteries. The 1.5V Photo Lithium batteries offer almost double the run time in a Perdix when compared to an alkaline battery. However they can cost about 4X as much as an Alkaline. They are a good choice if you want longer run time than alkaline batteries provide or if diving in waters colder than 8 degrees Celsius (46 degrees Fahrenheit) . They can be found in most department stores or electronics stores and also in many drug stores.
1.5V Zinc-Carbon batteries are el-cheapo batteries commonly found in dollar stores. Although they work, they only provide about 10 to 15 hours and so are not recommended. However if they are all you can get on a tropical island somewhere, feel free to use them. Set the Perdix battery type to “1.5V Alkaline” when using zinc-carbon batteries.
