Shearwater Perdix AI Dive Computer

Shearwater Perdix AI comes standard with no transmitter. During checkout please select no transmitter or Add Transmitter for $350.

Shearwater is proud to introduce the newest member of the Shearwater family: The Perdix AI. Offering all of the same great features of the Perdix, the Perdix AI uses its large, easy-to-read screen to clearly display the tank pressure as well as your gas time remaining (GTR). The Perdix AI is capable of connecting to either one or two transmitters giving the diver the option to monitor both tanks or dive sidemount.

The Perdix AI dive computer from Shearwater search, is a robust dive computer for technical divers of all levels, and ready out of the box for air, nitrox, and trimix gasses. The Perdix AI is the newest offering from Shearwater, similar in design an operation to the Petrel line of dive computers, but in a smaller form factor.

Its simple 2-button interface and easy to navigate menu structure allows for intuitive and quick operation underwater. The Perdix AI features a large, high resolution LCD screen is both easy to read, and power efficient. The Perdix AI operates on any AA sized battery, and is user-replaceable in the field with minimal effort. The included digital compass is both accurate and smooth, and Bluetooth integration offers download and upload capability from Mac, PC, and iOS devices.

The Perdix AI may be used for open-circuit and closed circuit-diving, as well as gauge mode if desired


The small form factor of the Perdix AI does not allow for an external connection for rebreather oxygen cell monitoring. Despite this, closed-circuit rebreather divers find the Perdix AI more than adequate for CCR decompression calculations using a manually entered PO2 setpoint.

In closed-circuit mode, the Perdix AI stores banks of 5 closed-circuit diluent gasses, as well as 5 open-circuit bailout gasses. In open circuit mode, 5 bottom mixes, and 5 decompression gasses may be stored. Gas switching is performed quickly and easily with minimal button pushes. Gasses may be added or edited while underwater – useful for lost gas scenarios.

Decompression Algorithm

The Shearwater Perdix dive computer features the following modes of operation:

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

All Shearwater dive computers use Buhlmann ZHL-16C as the decompression algorithm. User adjustable conservatism may be achieved by manipulation of gradient factors settings in the computer’s settings. An optional VPM-B algorithm may be purchased if desired, and installed in the field.

The 2.2" Color LCD display is easy to read, with high contrast, and automatic screen brightness. The display may be customized with user-defined font colors, and may be inverted for those who wish to wear the Perdix AI on their opposite arm. Several layouts may be selected from, and fonts may be customized for size and color.


The user interface is simple to use with adaptive menus. Commands are entered with piezoelectric buttons. Warnings are clear and concise using color-coded fonts. A simple 2-button bailout allows for quick and easy changes to open-circuit. No confusing icons are used; rather the Perdix AI navigation is done with plain-language. Divers have a choice of metric, or imperial units.


The Perdix AI operates with any AA-sized battery. Shearwater Research recommends the use of Duracell Coppertop alkaline batteries for their widespread availability, and reliability. Shearwater dive computers will operate about 30 hours on a quality alkaline battery, or up to 95 hours using Saft LS14500 batteries. Li-Ion, NiMH, Photo Lithium 1.5 and Zinc-Carbon 1.5 batteries may also be used.

The Shearwater dive computers also features a super-capacitor to keep track of your tissue loading in the event a battery change is required between dives. This capacitor holds enough energy to maintain tissue status for 15 minutes. This means that if your battery change takes less than 15 minutes you can continue with repetitive dives, and don’t have to reset the date and time.

The Shearwater Perdix AI features a 1000-hour dive log, which may be downloaded via Bluetooth to a Mac, PC or iOS device using free Shearwater Desktop. The Bluetooth feature may also be used to upload firmware updates, when available.

What makes a Halcyon backplate so unique?

Every Halcyon backplate features a host of subtle finishing details that enhance in-water performance, reliability, and diving comfort. These factors, together with the industry’s highest quality finish, set Halcyon backplates apart from the ordinary. Available in carefully finished Stainless Steel or mil.spec. hard-coated aluminum, the Halcyon backplate resists the oxidation and marring common in other less finished, yet similarly priced, plates. Individually milled edges combine with the high quality materials to provide the industry’s most sought-after backplate. In addition to our unparalleled quality and unique ergonomic shaping, each Halcyon backplate features attachment points for Halcyon’s Single-tank Adapter, Storage Pak, ACB Weight Pockets and the low profile (6 ft3) dry suit inflation bottle mounting straps.

Halcyon’s webbing slot angles have been designed to provide optimal comfort for the diver. During a dive, webbing slip is mitigated by the inherent grip of the slot on the webbing, enhancing diver performance and comfort. Halcyon webbing is manufactured exclusively to Halcyon specifications; our webbing is stiff enough to provide support but soft enough to allow a complete range of motion. The crotch strap features 2” soft webbing carefully selected to minimize wear points and prevent uncomfortable pressure points.

Description

OxyCheq Expedition O2 Analyzer

We heard they wanted a durable, compact oxygen analyzer with a user replaceable sensor, readily available batteries, a splash-proof case and and at a reasonable price. The OxyCheq Expedition Oxygen Analyzer meets this criteria and more. We designed an electronic circuit that is easy to calibrate and uses a long life sensor. We used most reliable parts made and enclosed the electronics and sensor in a compact, sturdy, custom molded ABS case. The case, digital panel meter, potentiometer, on/off switch, and sensor, are sealed to protect the electronics inside the enclosure from harsh elements. It is splash-proof. The "Expedition" comes with a compact carrying case with foam to protect your investment. It also has room for other items such as the optional remote flow restrictor, batteries, or a sensor. Both enriched air divers and technical divers will truly appreciate the compact size, durability, performance, ease of operation, reliability and sensor life. The Expedition set the standard in performance, price and quality for oxygen analyzers for the diving community. The OxyCheq Expedition Oxygen Analyzer uses a removable cap with a built-in flow restrictor. Although not necessary, you can also attach a 2-3 lpm flow restrictor to the sensor cap/flow restrictor if desired. Calibration can be made in air or pure oxygen and takes seconds. Once the sensor is calibrated, analyzing gas is easy. The user simply opens the cylinder valve until a slow, constant hiss is heard, places the sensor cap restrictor over the gas, and waits for a constant reading. The case and cap are extremely durable and there are no pliable rings to wear out or parts to break off. The sensor cap/restrictor also has the ability to sense gas remotely with an optional flow restrictor that can connect to a low pressure bc hose.

Changing the sensor or batteries is very easy. When you remove the back of our case, all of the electronics are located on the front half of the case. There are no wires attaching the back to the front that can result in strains on the leads when replacing the sensor or batteries.

In limited light conditions and if desired, the user can flip on the backlight.

The OxyCheq Expedition Oxygen Analyzer was designed with simplicity in mind. Once out of the box, the average user will be able to sample gas in minutes.

The "Expedition" was built to last and perform ... and it does. We did not take short cuts or use inferior parts to lower the quality of this unit, we simply took less profit. OxyCheq is known for our personal service and attention, we built the "Expedition" for you and have no doubt you will be extremely pleased with your purchase of this oxygen analyzer.
