As a relatively new company, these dive computers assist with providing demanding divers almost everything they desire.

There are plenty of fascinating elements in both the Teric and Perdix AI dive computers to consider.

About Shearwater Research

By adding his programming and advanced technical diving experience to the mix, their dive computers are incredibly innovative.

What you're bound to notice while wearing one of their devices is that they have high-tech features embedded in a simple user interface.

Divers will find it substantially simpler to deal with structural menus, minimal button pushes, optimal underwater clarity, and more.

Instead of opting for a mid-tier dive computer that lacks essential features, both the Teric and Perdix AI have the essentials and more.

Whether you're a technical diver or a recreational diver, you can easily find a device that suits your needs.

Another brilliant feature of Shearwater is that they are always looking to develop the latest and greatest technology.

Shearwater Research Teric Wrist Dive Computer

At first glance, you're bound to notice that the Shearwater Research Teric Wrist Dive Computer is in a league of its own.

Its fashionable design makes it ideal for wearing in relatively any situation, whether on land or water.

With a body that resembles an everyday timepiece but packed with innovative diving features, it's genuinely all-in-one.

Overview of Features

  • Low-Profile Design

The Teric will sit on your wrist like any other watch you might own, especially if you're a fan of smartwatches.

Its face is perfectly designed to display essential diving and everyday information, such as the date and time.

There are multiple watch faces that you can switch between, depending on the style you're trying to achieve.

  • Buhlmann GF Algorithm

Like other types of Shearwater tech, this dive computer boasts the Buhlmann GF algorithm for conservative divers.

With the help of Erik Baker, the company has allowed for high gradient factors to control the conservatism.

You can customize the efficiency of the device with ease, depending on your preferences.

  • AMOLED Screen

If you're looking for top-tier optics while underwater, we highly recommend considering the AMOLED screen built into this computer.

Not only does it offer full-color viewing, but the colors are substantially more vivid than with other dive computers.

Also, the AMOLED makes it one of the highest resolutions on the market so that you can see essential data in any condition.

  • Configurable Data Colors

One of the main reasons divers prefer color screens on their dive computers is the ease of use.

You'll allocate specific colors to certain metrics, such as yellow for air integration and red for decompression time.

Fortunately, this watch allows you to set custom colors for each set of data that you want to review while diving.

  • Multiple Diving Modes

Regardless of the type of diving you prefer, there are multiple modes to choose from that give you all the essential data you need.

    • Freediving: With the freediving mode, you'll have access to configurable sampling rates as well as improved descent and ascent rate indicators. You can also configure your haptic and audible alarms to disable them or adjust them for depth and time.
    • OC Recreational: With the OC recreational mode, you can set your Nitrox up to 99%.
    • OC Technical: This feature is essential for divers who prefer to use Trimix, as it's enabled.
    • CC/BO: With CC/BO, the dive computer will have a fixed PPO2 value.
    • Gauge: Often found in most dive computers, the gauge set is another diving mode to consider.
  • Optional Air Integration

Air integration is imperative for most divers, especially those learning the ropes.

With the optional integration with this dive computer, you can connect it to up to two transmitters at a time.

  • Durability

When you invest in a dive computer, you want to make sure it lasts a long time before showing signs of wear.

The Teric is one of the more durable options, primarily since it features a sapphire crystal window that withstands scratches and impact.

The bezel and the buttons on the outside of the device are made from 316 stainless steel.

  • Battery Life

You'll find a rechargeable lithium-ion battery that offers plenty of charge for frequent dives within the dive computer.

The personalization of your new dive computer doesn't stop at optional watch faces and customizable alarms.

The Teric also allows divers to change the color and type of strap they wear throughout the day and while diving.

There are a multitude of straps available separately from Shearwater if you want to show off your style.

  • Four-Button Design

It can be challenging to deal with multiple buttons on a single wrist dive computer, mostly when submerged.

This device features a simple four-button interface that allows you to adjust the light, access the menu, and display info.

The fourth one is a customizable function button, so each user can decide what they want it to do at their leisure.

  • Bluetooth-Enabled

You'll be glad to hear that the Teric is fully Bluetooth-enabled, allowing you to connect your watch to your phone or computer wirelessly.

With connectivity, you're able to upload your dive logs into the Shearwater program.

On a computer, you can display your dive logs using several eye-catching charts and graphs for review.

You'll feel far more hydrodynamic and have a heightened ability while navigating underwater.

  • Two-Button Interface

Divers looking for the most straightforward user interface will love the two-button design that this model features.

It's incredibly easy to navigate through the menus, mainly because it features a state-aware concept.

Depending on the dive mode you choose, nearly every segment on the home screen can be adjusted.

It's also important to note that the Perdix AI offers several different languages to choose from.

You'll switch from English to French, Simplified Chinese, Traditional Chinese, Japanese, Korean, German, Portuguese, Spanish, and Italian.

  • Heavy-Duty Case
