Shearwater Research Teric Wrist Dive Computer Review

Computer technology has brought significant developments in diving safety, performance, and convenience–advancements symbolized by the sleek, Bond-like multi-purpose computer wristwatch. The future is here, and it’s under warranty.

As an experienced diver, you are prepared to invest in your equipment and knowledge to do the research necessary to sort through available options and features. In this article, we’ll review Shearwater Research’s Teric wrist-mounted dive computer and see how it compares with the competition.

Shearwater Research Teric Wrist Dive Computer

Purchasing a dive computer for experienced and technical divers

Even experienced divers vary their locations and technical demands—and we all seek flexibility and the convenience of automation. A quality dive computer requires solid performance and monitoring capacity, preferably in a unit that adjusts to the conditions of your dive.

Reliability is non-negotiable for diving equipment. You want a well-designed model with a solid warranty from a reputable manufacturer: preferably one with experience in the advanced diving market. A dive computer should be well-designed and constructed to resist corrosion and degradation from routine wear.

Only you can decide upon the versatility you need, so match those needs against your final selection. You will enjoy the ability to customize features, but without sacrificing technical precision or craftsmanship. Some wrist-mounted dive computers with broad applicability lack the specialization you need, so you’ll have to decide what matters most.

Don’t forget the day-to-day experience either! Consider the intuitiveness and usability of the menu system and display, and the level of automation you desire. Ideally, you’ll find the right balance between the precision and control you need, and the automation and convenience you want.

Presenting the Shearwater Teric

The Shearwater Research Teric is a high-performance technical dive computer housed in a distinctive and attractive wristwatch. It is made with recreational divers in mind but includes high-end technical capabilities for versatility and range.

The Teric is simple to operate, but its complexity is over-the-top for beginners. If you’re experienced and know what you need, however, this unit puts style into cutting-edge performance. The unit’s five dive modes cover depth conditions of up to 656 ft (200m) and automate everything from turning itself on to tracking your dive parameters and uploading your log when done.

Since the Teric provides performance and versatility in a great-looking wrist-mounted computer–along with its loyal customer base and early adopter interest–it is unsurprisingly priced at a premium. There are cheaper computers you can find. As a quality instrument, however, it makes sense to consider the Shearwater Teric more closely.

As an added consideration, the Teric can quickly change its face to double as a land wristwatch—it’s a downright bargain when viewed as part of the market for high-end timepieces.

Features & Benefits

Multiple Dive Modes

The Shearwater Teric comes with five different diving mode settings for versatile performance, so you can quickly change the configuration according to your intended dive.

You can configure specific sampling rates for different kinds of diving, and monitor time-to-surface numbers for pre-planned gas switches. The Teric allows you to program unique mixes for each mode, with multiple gas definition presets for any combination of nitrogen and oxygen, and also helium for use in other than the recreational mode.


For use during no-decompression diving activities. This mode can monitor three gas mixes and uses nitrogen and oxygen only (no helium). The setting includes an adaptive safety stop and No Decompression Limit (NDL) Bar Graph so you can see how much time you have before a mandatory decompression stop. Enhanced warnings keep you informed about your limits during a casual dive.

Open-Circuit (OC) Technical

For use on technical dives, including planned decompression. 5 OC gases with full Trimix enabled by default. There are no safety stops, and Time-to-Surface (TTS) is prominently displayed throughout the dive.


Designed for monitoring a closed-circuit rebreather, with Bail-out (BO) operation and quick switchover to Open Circuit use. Constant PO2 is maintained to minimize decompression restrictions, and you can program up to 5 OC/5 CC gases.


Simple monitoring of dive time and depth, with resettable stopwatch and timer functions. No tissue tracking or decompression monitoring.


This mode shares most features of the other dive modes, with the addition of special monitoring that applies to free diving. The large layout format is enabled by default and displays the Last Dive Time and Max Depth. Ascent and Descent indicators can be set in 1-second intervals.

Advanced Display Features

The Teric inherits and advances the innovative screen functions of its predecessor, the Shearwater Perdix, a unit well-regarded for its readable and intuitive display.

  • A Sizeable 1.39 in (35mm) AMOLED screen offers a vivid full color, high-resolution display that is easy to read underwater.
  • The sapphire crystal face is highly scratch resistant: it rates as a nine on the Mohs hardness scale, just below diamonds. The casing buttons and bezel are made of 316 stainless steel, so you don’t have to worry about rust or salt corrosion.
  • The 4-button Teric interface is even easier to navigate than the 2-button Perdix menu system. You can also program one button for single-press access to specific functions for quick access to your most useful tools. You can configure the screen to different layouts and font sizes, and to display the exact information you want to see at a glance.
  • Alarms can be set for either haptic (vibration) or audible alerts, so you can choose your preferred method and avoid bothering nearby divers too. Besides dive alerts, you can set 2 independent alarms to trigger daily, with options for weekdays/weekends and adjustable snooze time.
  • The Teric provides a three-axis, tilt-compensated digital compass. Its readings show on the outer edge of the display.
  • You can configure the home screen, so the information you most need is conveniently displayed.

Changeable Face

Another handy feature is the ability to change the watch face for use as a regular wristwatch. There are three faces–Digital, Analog, and Orbits—and you can set over 100 possible configurations using the three information levels and different faces and color combinations.

The Dive Mode automatically switches to Watch Mode after 15 minutes on the surface. It will remain powered, but the dive computer turns off its main functions after 20 minutes if no motion is detected.

Watch Tools

The Stopwatch setting operates across all dive modes and runs up to 24 hours even if turned off. There is a Timer function too, and a Flashlight setting that brightens the display—it won’t illuminate the ocean deeps but may be useful at close quarters in low-light conditions.

Rechargeable battery

The Teric is powered by a lithium-ion battery rated for 5+ years of use. It is wirelessly recharged in about 1.5 hours when using the docking station, and can also be charged with most Qi-compliant pads. Depending upon the settings, a single charge lasts from 30 to 60 hours.

One inconvenience is that the battery requires a dealer to change. No swapping out spares, so you need to remain aware of the battery status.

Digital integration

The Teric is equipped with Bluetooth Smart technology so that you can upload your dive logs automatically to your preferred device. It’s compatible with Mac, Windows, iOS, and Android, making it easy to update your system and manage your information.

Warranty & Service

The Teric comes with a 2-year warranty, and Shearwater Research has a positive customer service record. Each Teric has a unique serial number that doesn’t require registration and can be transferred if sold.


The Teric can connect wirelessly with up to 2 transmitters, but you must purchase this equipment separately. The feature can be added at any time, however, if you aren’t sure about making the outlay quite yet.

The wristband comes in several optional dual-color schemes you can purchase additionally: Pink, Blue, Green, White, and Yellow. The straps are interchangeable with any 22 mm watch band type.

Social Proof

Hearing directly from users about their experience is essential to any objective evaluation, and the Teric is already attracting favorable attention. Here are a few samples of user feedback found online:


Aqua Lung i450T

The Aqua Lung i450T is a wrist-mounted dive computer introduced in 2016 and remains one of the excellent competitors to Shearwater’s Teric. The 1450T was stylish for its time and shares the theme of flexibility and convenience the Teric has developed further.

The i450T features four diving modes, lacking the CC/BO rebreather mode and higher automation of the Teric’s recreational settings. The display is intuitive and easy to read, though it lacks the color and highly customizable interface that makes the Teric stand out visually.

The i450T excels at air integration, offering control of up to 3 transmitters instead of Teric’s dual capacity. Its battery is replaceable by users too, so you’ll be saved a trip to the dealers when its time to change.

Overall, Aqua Lung’s unit today represents a pared-down feature set when compared to the Teric, but it’s a reliable tool at a slightly lower cost.

  • Stylish but single-color face
  • Lacks rebreather monitoring
  • User-replaceable battery

Suunto D6i Novo

The Suunto D6i Novo is an established wrist-mounted dive computer that is a close competitor to the Teric and comes with a similar price tag too. As an older model, it has a bit less under the hood than Shearwater’s latest effort, but it is well-tested and reliable.

The D6i is excellent for free diving, and the longtime market presence of Suunto makes it easy to find assistance across the world. It doesn’t have a mode for CC/BO rebreather tech, but it has similar automation to the Teric—including an optional transmitter and the need to have its battery replaced by a dealer. The D6i has a duller, black LED face, and small buttons that have been known to stick without extra care.

The D6i is well-regarded by professionals, and it’s in the same price range as the newer Teric. It doesn’t have quite the same level of digital integration or automation, but it’s still a solid choice if you have the budget.

  • Small buttons
  • Lacks rebreather monitoring

Oceanic Oci

The Oceanic Oci is an older model that combined the technical advancement of the OC1 with the stylish and popular OCS model. It is in the same price range as the Shearwater model, and looks great and performs well.

Oceanic OCi Wrist Wireless Air-Integrated Dive Computer Complete

Though it lacks full-color display or the Teric’s versatility and range, the Oci is established and offers all most recreational diver’s need. You get four wireless transmitter capacity, and user-replaceable battery power, and an established customer base.

The Oci package includes the transmitter, which makes it more affordable than the Teric if you need air integration. It’s an older model that compares favorably concerning reliability, and its slightly smaller feature set present a less complicated tool for less experienced divers.

  • Includes wireless transmitter
  • Lacks full-color display


It’s hard to keep up with the latest innovations: you want the best of essential advances while avoiding the gimmicks. An advanced diver can’t sacrifice precision and reliability, but versatility and ease of use are critical for day-to-day convenience.

Shearwater Research Teric Wrist Dive Computer

Good looks don’t hurt, and the Shearwater Teric offers it—along with the solid performance demanded by experienced divers. The Teric represents the next generation of dive computers and gives the flexibility to meet most diving techniques and occasions. It’s a diving computer with style.
