All You Need To Know About The Shearwater Peregrine Dive Computer

The Shearwater Peregrine is the latest addition to the Shearwater Research line of dive computers. Shearwater is known in the scuba diving community for making high-tech and robust dive computer gear for professional and technical divers, like the Petrel and the Perdix.

The Peregrine is their first dive computer designed specifically for recreational divers, but don’t let that fool you – it’s still packed with features and technology usually only found in higher-end models.

Color Display

One of the first things you’ll notice about the Shearwater Peregrine is its colorful and easy-to-read display. Just like the Perdix, the high-resolution 2.2-inch screen boasts a bright backlight, making it easy to read even in low-light conditions. The display also offers some customization and allows you to display important dive information in a way that best suits your preference.

Two-Button User Interface

One of the things the Perdix was also known for was its simple two-button user interface, and we were glad to see that this feature also carried over to the Peregrine. This user-friendly design makes it easy to navigate through the menus and customize settings without having to constantly refer back to the manual.

Four Diving Modes

The Shearwater Peregrine shines when it comes to diving modes. It offers four different modes to cater to a broad spectrum of diving activities. Here they are:

  • Air Mode: This mode is for those who prefer to dive with regular air. It’s straightforward and perfect for beginner divers.
  • Nitrox Mode: Nitrox mode is for divers using enriched air nitrox. The Peregrine allows you to adjust the oxygen concentration up to 40%, giving you more bottom time and reducing decompression sickness risks.
  • 3 Gas Nitrox Mode: This mode is designed for light technical diving. It adds more versatility by enabling you to program up to three different nitrox mixes (up to 100% oxygen) and allowing you to switch between them underwater or between dives. 
  • Gauge Mode: Gauge mode turns the Peregrine into a simple depth gauge and timer, making it great for tech divers or as a backup for a more advanced computer.

Bühlmann ZHL-16C Algorithm With Customizable Conservatism

The Shearwater Peregrine uses the trusted Bühlmann ZHL-16C algorithm. You can adjust the conservatism level to three different settings – low, medium, and high. There is also a ‘custom’ option for you to manually change the gradient factor, making it suitable for different diving profiles and individual preferences.

Battery Life

One of the things we love about the Shearwater Peregrine is its rechargeable battery and excellent battery life. On medium brightness, it can last up to 30 hours – perfect for a full day of diving. It also comes with a USB wireless charging pad, or you can use any Qi-compatible wireless charger. 

Vibration Alerts

The computer comes with vibration alerts that you can customize to notify you when you reach certain depths, dive time, or a specific ascent rate. This feature is perfect for those who don’t want to be distracted by audible alarms and prefer a more subtle alert system.

Internal Dive Log and Connectivity

The internal logbook of the Shearwater Peregrine stores up to 200 hours of dive data, including dive profiles and surface intervals. You can also connect the Peregrine to your computer or smartphone via Bluetooth to download and analyze your dives using the Shearwater Cloud app.

What We Like 

There are so many this we like about this dive computer. Below are some of the features we like most about the Peregrine.

  • User-friendly interface – Navigating the menus is very simple and makes it easy when you need to change your nitrox % or any other setting.
  • Bright color display with customization options – Being able to read diving information is crucial, and Peregrine’s color display with customizable options ensures that you can see what you need without any difficulty.
  • Wireless charging – With wireless charging, you no longer have to worry about changing batteries or cables. Simply place the Peregrine on its charging station and let it power up for your next dive. This also reduces the chances of you flooding the dive computers, since there are no batteries to change.
  • Bluetooth – With Bluetooth connectivity, you can easily transfer your dive data to your electronic devices without any hassle. This also allows for easier firmware updates and language changes through the Shearwater Cloud app.
  • It Won’t Lock You Out – The Peregrine will never lock you out for deco violations like other recreational dive computers.
  • Vibration Alerts – Perfect if you prefer a more subtle alert system and don’t want to disturb other divers or be distracted by audible alarms. We all know that one diver with his computer beeping the entire dive.

What We Don’t Like

  • Lack of Air Integration – Although not essential, some divers may miss having air integration with their dive computers. If this feature is important to you, we would recommend buying the Perdix 2 or Teric Dive computer.
  • No Audible Alarms – As mentioned earlier, some divers may prefer audible alarms instead of just vibration alerts. However, this is a personal preference and does not negatively affect the performance of the Peregrine.
  • No Built-In Compass – Some divers may prefer having a built-in compass on their dive computer for navigation purposes. However, this feature is not essential and can easily be replaced with a separate compass.

How Does The Shearwater Peregrine Compare To Other Dive Computers?

The Shearwater Peregrine has many competitors on the market today, each with its own unique features and advantages. Below are what we think about some of its top competitors.

Shearwater Peregrine vs. Shearwater Perdix 2

The Perdix 2 AI is an upgrade of the popular Perdix dive computer, with added air integration capabilities. This makes it a great option for those who prefer having their tank pressure displayed on their dive computer. However, the Peregrine offers a more affordable option for divers who do not need this feature.

Shearwater Peregrine vs Shearwater Teric

The Teric is Shearwater’s most advanced and feature-packed dive computer. It comes with a built-in compass, multiple air integration options, and a stainless steel bezel. However, it also comes at a much higher price point compared to the Peregrine. If you are an advanced diver looking for more advanced features, then the Teric would be a better option for you. Otherwise, the Peregrine offers great value for money with all the necessary features for recreational divers.

Shearwater Peregrine vs Aqualung i300c

The Aqualung i300c offers similar features to the Peregrine, such as wireless data transfer and customizable display options. However, it lacks in terms of battery life, with only 40 hours compared to the Peregrine’s 200 hours. Additionally, the Peregrine has a more user-friendly interface and offers more dive modes for divers who want a bit more versatility.

The Bottom Line

Overall, we highly recommend the Shearwater Peregrine as the best dive computer for recreational and entry-level tech diving. Its user-friendly interface, customizable display, wireless charging, Bluetooth connectivity, and other features make it a great value for its price.

While it may not have all the bells and whistles of higher-end models, the Peregrine is a solid choice for any diver looking for a reliable and functional dive computer.
