The Perdix 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 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 features a large, high resolution LCD screen is both easy to read, and power efficient. The Perdix 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 may be used for open-circuit and closed circuit-diving, as well as gauge mode if desired - no pin upgrades are needed.

Stand-Alone:

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

In closed-circuit mode, the Perdix 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 â€Ã¢€Å“ 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 computerâ€Ã¢â€žÂ¢s settings. An optional VPM-B algorithm may be purchased if desired, and installed in the field.

A unique 'tissues' display gives a wonderful graphical representation of your tissue loading while diving. Display 

Display:

The 2.4" 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 Petrel on their opposite arm. Several layouts may be selected from, and fonts may be customized for size and color.

 

 

User Interface:

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 navigation is done with plain-language. Divers have a choice of metric, or imperial units.

 

Battery:

The Perdix 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.

Connectivity:

The Shearwater Petrel 2 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. Shearwater Research desktop program.
