Air Integration with the Shearwater Swift Transmitter

The 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.

Optional VPM Upgrade

The Perdix 2 Ti 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.

How to install VPM-B and VPM-B/GFS

Once you purchase a VPM-B upgrade pin for your Shearwater Perdix, you will receive an email with the unlock code for your unit's serial number within 72 hours.

Firmware

First and foremost, please ensure you have downloaded and installed the latest firmware before doing anything else. The easiest way to update your firmware is to download the new Shearwater Cloud and select Dive Computer-> Update Dive computer. Follow the instructions on the screen, and Shearwater Cloud will handle the rest.

System Settings

Once the unit runs the latest firmware, scroll to System Setup using the left-hand button. Using the same button skip Mode, Deco, AI, Row, Gases, Alerts, Display and Compass screens and reach the System Setup screen with Date, Clock and Unlock rows underneath.

Press Edit (right button), then Next > Next, and Edit the Unlock row, which will have zeros (0's throughout). Using the Change option and Next as you complete each entry, enter the unlock code you received and press Save when completed.

The unit will reset and restart if you have entered the correct unlock code. If there is a mistake, you will receive an "Invalid" notification to repeat the above.

Mode Setup

From the main screen now return to System Setup and using the Next (left-hand button) go to Mode Setup. Edit the Mode to show OC Tec or CC/BO - if not already selected. VPM-B and the safer VPM-B/GFS will only be available if open circuit technical or rebreather mode is selected. Otherwise, the unit will default to Bhulmann with GF options. Once in OC Tec or CC/BO mode, the VPM options can be selected.

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 the warranty does not cover unauthorised repairs, modifications, accidental damage or negligence.

To benefit from this manufacturer warranty, you need to contact the Shearwater support team directly at info@shearwater.com or fill out the RMA form at https://www.shearwater.com/rma-request-form/ . 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 https://www.shearwater.com/support/ to process local warranty issues.

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

This and other questions are answered directly by Shearwater Research in the online FAQ. Please click on Shearwater Online FAQ and select the Perdix from the top menu. You can also download the current Perdix Manual. Feel free to contact us any day, we are open every day.

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.

Alkaline
Shearwater recommends the AA 1.5V alkaline battery (e.g. the Duracell Coppertop) because it is:

• Inexpensive
• Available anywhere
• Reliable
• 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.

Saft
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:

• Expensive
• 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.

Zinc-Carbon 1.5V
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.
