Conventions Used in this Manual
These conventions are used to highlight important DANGER information: This computer is capable of calculating decompression stop INFORMATION requirements. These calculations are at best a guess of real physiological Information boxes contain useful tips for decompression requirements. Dives requiring staged decompression getting the most out of your dive computer. are substantially riskier than dives that stay well within no-stop limits. Diving with rebreathers and/or diving mixed gases and/or performing staged decompression dives and/or diving in overhead environments CAUTION greatly increases the risk associated with scuba diving. Caution boxes contain important instructions YOU REALLY ARE RISKING YOUR LIFE for operating your dive computer. WITH THIS ACTIVITY.
WARNING Warning boxes contain critical information that may affect your personal safety. WARNING This computer has bugs. Although we haven’t found them all yet, they are there. It is certain that there are things that this computer does that either we didn’t think about or planned for it to do something different. Never risk your life on only one source of information. Use a second computer or tables. If you choose to make riskier dives, obtain the proper training and work up to them slowly to gain experience.
This computer will fail. It is not whether it will fail but when it will fail. Do not depend on it. Always have a plan for how to handle failures. Automatic systems are no substitute for knowledge and training.
No technology will keep you alive. Knowledge, skill, and practiced procedures are your best defense (except for not doing the dive, of course).

1. Introduction
The Shearwater Peregrine is a dive computer for beginner to expert divers.
Please take the time to read this manual. Your safety may depend on your ability to read and understand the Peregrine displays.
Diving involves risk and education is your best tool for managing this risk.
Do not use this manual as a substitute for proper dive training and never dive beyond your training. What you don’t know can hurt you.

Auto-on Details 2. Basic Operation The Peregrine turns on automatically when the absolute pressure is greater than 1100 millibar (mbar).
2.1. Turning On For reference, normal sea level pressure is 1013 mbar and 1 mbar of pressure corresponds to approximately To turn the Peregrine on, press both buttons together. 1 cm (0.4”) of water. So, when at sea level, the Peregrine will automatically turn on and enter dive mode when about 0.9 m (3 ft) underwater.
If at higher altitude, then the Peregrine auto-on will occur at a deeper depth. For example, when at 2000 m (6500 ft) altitude the atmospheric pressure is only about 800 mbar. Therefore, at this altitude the Peregrine must be submerged underwater by 300 mbar to reach an absolute pressure of 1100 mbar. This means the auto-on occurs at about 3 m (10 ft) underwater when at an altitude of 2000 m.
Customizable Splash Screen After turning on, the Peregrine Splash Screen is displayed for 2 seconds.
Auto-on Customizable start up text can be added using the The Peregrine will automatically turn on when Shearwater Cloud Desktop app. submerged underwater. This is based on pressure increase and not on the presence of water. When The image itself can also be customized using the auto-on is activated, the Peregrine will enter the last Shearwater Cloud Desktop App. configured dive mode. See the section on Connect to Shearwater Cloud Desktop on page 44 for details. Do Not Rely On The Auto-On Feature This feature is supplied as a backup for when you forget to turn on your Peregrine.
Shearwater recommends turning your computer on manually before each dive to confirm proper operation and to double check battery status and setup.

3. Mounting Options 3.2. Shock Cord
The Peregrine is shipped with both a silicone strap and Shock cord or bungee can be installed in many ways on shock cord. Before first use, you will need to install the Peregrine. The Peregrine’s holes are sized for 4mm your preferred mounting option. cord.
The simplest option is to secure the shock cord is with four simple overhand knots. However, this method 3.1. Silicone strap is not adjustable and a knot might pull through its mounting hole at very high load. The included Peregrine strap is made of a durable, stretchy silicone, designed to grip a wet suit or dry suit Another method is to use slip knots. This provides without sliding around. Several strap colour options are adjust ability when changing exposure protection. available (black is included).
The strap is fastened to the Peregrine via stainless steel lugs which can be easily removed and replaced with two standard Phillips screwdrivers (included). The lug threads come with a pre-applied locking element that performs best when tightened fewer than 5 times.
DO NOT OVER TORQUE LUG SCREWS Once it feels tight, stop screwing. Over torquing can damage screw threads.

Vibration Alerts In addition to visual notifications, the Peregrine has vibration alerts to help quickly notify the diver of warnings, errors and dive events.
If turned on, attention vibration alerts occur when a safety stop starts, pauses, or is completed. Vibration alerts will also occur any time a primary notification is triggered and every 10 seconds until it is acknowledged.
The vibration alert settings can be changed in the Limitations of Alarms System Setup menu as described in Alerts Setup on page 40, or in the Dive Setup menu described on All alarm systems share common weaknesses. page 36.

The mounted on the included dock and on some third Peregrine has internal protection which disconnects party wireless Qi compliant chargers. the battery before complete discharge occurs. However, a small amount of self-discharge still occurs, which can lead to complete discharge and subsequent battery damage if stored for long periods without recharging.
To prevent damage to the battery please do the following:
1) Charge the Peregrine to 100% prior to storage 2) Top up the Peregrine battery every 3 months
Charging time The Peregrine can be charged with any USB wall power adapter or with a computer. Charging time is approximately 2 hours. The screen will dim after 20 seconds, but pressing any button will wake up the Peregrine.
Charger Positioning Wireless chargers quickly lose efficiency when the transmission and receiver coils are not aligned properly or there is too large an air gap.
Ensure the Peregrine is flat against the charging dock for the fastest, most efficient charge.
If the Peregrine stops charging and the charger light begins to flash red, remove and replace the Peregrine and charging should resume.

14. Glossary
CNS - Central Nervous System oxygen toxicity. Adverse physiological affects from prolonged exposure to an elevated partial pressure of oxygen. Deco - Decompression. The state of requiring mandatory decompression stops or the act of performing those stops. NDL - No-Decompression Limit. The time, in minutes, that can be spent at the current depth until mandatory decompression stops will be required.
O2 - Oxygen gas. OC - Open circuit. Scuba diving where gas is exhaled into the water (i.e. most diving).
PPO2 - Partial Pressure of Oxygen, sometimes PPO2. TTS - Time To Surface. The amount of time required to surface given an ascent rate of 10m/min, including all required mandatory decompression stops.
