Shearwater Perdix AI - At a glance
Bluetooth Ready - Connect your Perdix AI to your Desktop Computer
Sometimes it's the little things that make all the difference.
This dive computer is one of the few equipped with Bluetooth. This allows you to download your dive logs from the dive computer and view them on your desktop (both Windows and Mac) with lower power consumption. Bluetooth Smart Ready will also download to iOS devices such as an iPad and iPhone.
Being Bluetooth capable also makes regular firmware updates and upgrades very easy to install. The computer does all the work.
I bought a Shearwater Perdix once I realized I could read the screen of a Petrel on a student's arm 6 feet away, better than I could read the screen of my own dive computer.
What's the Price of the Shearwater Perdix vs Perdix AI Dive Computer?
You can buy the Shearwater Research Perdix AI for under $1200 including the Air Transmitter. If you go with the Perdix AI without the transmitter, these are currently selling for less than $950.
The price of the Perdix pre-air integration has dropped to below $850. If you don't want to go down the path of air integration, then this is the time to really pick up a bargain.
What’s the difference between the Perdix and the Perdix AI?
Shearwater released the Perdix AI in November 2016. There are only a few small differences between the Perdix and the Perdix AI.
The Perdix AI has wireless AI connection capability. This can connect with up to 2 transmitters making it ideal for sidemount diving.
There are also additional reporting features in ‘Shearwater Desktop’ specifically for the Perdix AI. This includes displaying the tank pressure throughout the dive, your SAC rate, as well as Gas Time Remaining (GTR) information.
The Perdix is still available to buy. The Perdix does not have the firmware for air integration and it's not something that can be retro-fitted later on. If you'd like a Perdix without AI, then there are savings to be had as there are plenty of these still available for sale.
Why are Shearwater Research Dive Computers held in such high regard?
Shearwater as a company, stand behind their products like very few others ever do.
Shearwater dive computers are designed and built for divers, by a group of enthusiast divers who also happen to be engineers and technologists. They are committed to providing the best sales and customer service experience they can.
Their Customer Service is excellent. Their service is backed up with video tutorials to help you get comfortable quickly with your dive computer. Having said that, there's no steep learning curve with the Perdix. They are easy to use and customize.
Shearwater Perdix - Optional Wireless Air Integration (AI)
At DEMA last year, Shearwater surprised many in the diving community by releasing the Perdix AI (with Air Integration).
If you're not a fan of air integration, then this is still the dive computer for you. The transmitter is an optional accessory. If you don't want wireless air integration, then there's no need to invest in the transmitter.
Each Shearwater transmitter has a unique serial number. This needs to be entered into the Perdix AI the first time you use it. The transmitter is screwed into the first stage of your regulator.
The Perdix AI is able to connect to either one or two transmitters giving you the option for monitoring two tanks and allowing for side mount diving. It's capable of displaying tank pressure in all modes.
The video below shows how easy it is to set up the Shearwater Perdix AI for wireless air integration.
Perdix AI Dive Computer - All the Bells and Whistles
The focus for Shearwater is on innovative and simple displays that keep the most important information easy to read at a glance. The Perdix only has two menu buttons so there's no excessive scrolling and guessing.
The display is 2.2 inches across with vivid color range and saturation. This big display can easily be read in any depth. The display automatically adjusts its intensity based on the light available. It will be easy to read whether on the surface in sunlight, in open water or in a cave.
The Perdix will automatically turn itself on once submerged. It doesn't have wet contacts so this is based on the increase in pressure, and not in the presence of water. Although you should always turn on the computer before each dive to check the battery level and its setup, this feature is a backup in case you forget to turn it on.
The Perdix comes with a 3 axis, tilt compensated digital compass.
Its case is rated to a depth of 260 meters / 850 feet, however, the guaranteed depth accurate range is to 130 meters / 435 feet. The depth sensor does continue to function to this depth, but with reduced accuracy.
This is the easiest dive computer to use and customize to show what's important to you. The dive number can be changed - It doesn't have to start at Dive #1. It can be changed to match the actual number of dives you have done.
The Shearwater Perdix AI will NOT lock you out when things don't go as perfectly as the computer thinks they should. If you foul up and realize you have the wrong gas mix selected you can change to the correct one (or even add a mix) as soon as you realize.
Perdix AI Diving Modes - Open Circuit and Closed Circuit
The Perdix AI is a technical dive computer will take you from your first open water dives (in recreational OC mode) all the way to trimix diving with the option of 5 CC gasses (in CC INT mode).
- Air / Nitrox / Trimix capable
- 5 open-circuit gas switch presets
The Perdix AI will not "lockout" after a missed stop or ascent rate violation.
|OC Rec||3 gas nitrox recreational computer|
|OC Tec||Multi-gas, trimix decompression computer|
|CC INT||Closed circuit fixed PPO2|
|Gauge||Bottom timer with stopwatch and dive logging|
Which Decompression Model does Shearwater Research use?
The VPM-B decompression model is available by purchasing an unlock code. These are the most common decompression models used by Technical divers.
What about battery changes and rechargeable batteries?
The Perdix AI uses AA batteries or long life lithium batteries. The battery compartment has a double o-ring to ensure a great seal.
The Perdix AI also takes rechargeable batteries but you can’t use rechargeable alkaline batteries which are your standard AA type batteries.
It takes rechargeable Li-ion 3.7V batteries although these are sometimes hard to source. These cost around $12 per 2x pack and will provide around 34 hours of charge.
The other rechargeable batteries it works with are NiMH 1.2V batteries. These are much easier to source and cost around $9 for a 8x pack. These will give around 30 hours of charge.
All dive logs and settings are saved in permanent memory so these are restored after a battery change.
What about Water Salinity adjustments and Language Choices?
The Perdix doesn't measure water depth directly. It measures the water pressure then converts this to depth based on the assumed density of water.
The Salinity setting on the Perdix can be set to Fresh, EN13319, or Salt. EN13319 is the European CE standard for dive computers. The density value used for each setting is:
- Freshwater = 1000 kg/m³
- EN13319 = 1020 kg/m³
- Salt Water = 1030 kg/m³
The Shearwater Perdix AI can be displayed in a range of languages. These are English, French, German, Spanish, Italian, simplified Chinese, traditional Chinese, Korean or Japanese.
What Maintenance is required for the Perdix AI?
Wash your dive computer with fresh water at the end of each dive in salt water to remove salt and other contaminants. Never allow salt deposits to build up. Detergents or other cleaning agents will damage the Perdix, so only use fresh water when rising.
Never wash with high-pressure water as it may damage the depth sensor. Allow the dive computer to dry naturally before storing. Keep the Perdix upright when storing, and out of direct sunlight in a cool, clean, dry and dust-free environment.
Avoid over exposure to direct ultraviolet radiation (the sun). It also doesn't like radiant heat.
As batteries can and do leak, always remove batteries from the dive computer when storing for long periods (several months). Dead batteries pose a higher risk of leaking and damaging the dive computer.
Warranty and Servicing for Shearwater Dive Computers
Shearwater Research provides after-sales customer service that is unparalleled.
Shearwater has a 2 year warranty on all of their products. Each dive computer is tracked with a unique serial number so it doesn't need to be registered after purchasing. This is transferable to the next owner if sold. Once the warranty period has passed, the computer should be serviced on an annual basis at your nearest service center.
Don't be swayed against buying the Shearwater because it would be 'too much computer' for you.
These are reliable and are easy to read in all diving conditions. Owners of the Shearwater dive computers claim these are the best dive computers they've ever owned. Comments such as this are repeated time and again across Scuba forums such as Scubaboard.
This dive computer also has 5 out of 5 Stars and 100% positive feedback on Amazon.
In regards to long term return-on-investment, Shearwater dive computers retain a very good resale value. If you had to sell one (although it's unlikely that you'd want to), it holds its value very well compared to its competitors.
This dive computer does exactly what it's supposed to do. As far as dive computers go, it provides the best bang for buck, and will simply last and last.
