Shearwater Teric with SWIFT: The Best Dive Computer I’ve Owned

If you want a dive computer that transitions seamlessly from recreational to technical—and even freediving—the Shearwater Teric, paired with the SWIFT transmitter, is an exceptional choice. It delivers everything I value: stylish design, reliable performance, and streamlined functionality.

Elegant Watch-Style Design, Customised to You

The Shearwater Teric looks and feels like a sleek wristwatch. It features a vibrant 1.39″ AMOLED display beneath a sapphire crystal, surrounded by a 316 stainless steel bezel and buttons  . Its watch-style aesthetic is enhanced by interchangeable 22 mm straps. Added to this you can customise the display with different colours to match your strap, mood, or dive gear.

Display & Compass – Clear and Always Available

Underwater clarity matters. The AMOLED screen is sharp and easy to read, even in strong sunlight or low visibility. Crucially, the built-in 3-axis, tilt-compensated compass can remain always-on, making it my go-to for underwater navigation.

Battery & Charging – Long-Lasting and Convenient

After two one-hour dives, the Teric had only used around 8% of its battery. That’s impressive even by 30-hour dive rating standards  . It supports wireless charging via Qi-compatible pads or its own induction stand  .

I have heard some users report battery performance softening after two years, but wireless charging keeps it hassle-free .

Controls & Alerts – Four Buttons, Intuitive Navigation

The Teric’s four physical buttons unlock a menu system designed around situational logic. One button can be customized for quick access to tools like the compass or stopwatch  .

Alerts can come through vibration instead of annoying loud beeps, which is practical and less obtrusive in dive settings. That being said, it can beep if you wish.

Air Integration – SWIFT Transmitter Compatibility

With support for up to four SWIFT transmitters, it’s ideal for both recreational and sidemount technical dives  .

I’ve used two transmitters when diving sidemount. The Shearwater Teric handles GTR (Gas Time Remaining) and pressure monitoring flawlessly  .

SWIFT’s smarter transmission avoids interference issues common in multi-tank setups  .

Do note: I recommend carrying a backup SPG in the unlikely event you were to get a rare SWIFT failure.

Diving Modes & Usability

Whether you’re freediving, recreational diving, open-circuit tech, or closed-circuit, the Teric has a mode for it  .

Menu navigation is easy. In the field, I consistently manage settings using just the four buttons. Transitioning between freedive, recreational, and technical dives is seamless.

Logging & Connectivity

Bluetooth syncs dive logs effortlessly with Shearwater Cloud, and I link it to MacDive for reliable record-keeping.

Sadly it doesn’t connect with PADI or SSI log apps—but that’s due to their app architectures, not Shearwater’s  .

Downsides – What to Keep in Mind

• Watch face activation requires pressing a button, not a cover-up feature but a battery-saving design. A bit annoying when wearing it as a watch
• Screen size could feel small compared to models like the Perdix. But the clarity of a high-res AMOLED display compensates  .
• Price puts it in premium territory, with price north of $1000. But for what it offers in build quality, battery, display, air integration, it delivers significant value.

Final Thoughts

The Shearwater Teric with SWIFT is the best dive computer I’ve ever used. It blends high-end design, usability, and depth of functionality masterfully. Whether you dive recreationally, explore technical depths, or practise freediving, the Teric covers all bases without overwhelming complexity.

If you appreciate a sophisticated watch-style computer and value clear underwater visibility, long battery life, dependable air integration, and intuitive operation—you’ll find this is a worthwhile investment.

If You Don’t Need All the Features: Consider Tern TX or Peregrine TX

Not every diver needs the full feature set of the Teric. If you’re after a sleek, capable dive computer without the technical dive bells and whistles, these two models are excellent alternatives:

Shearwater Tern TX

• Compact, watch‑style design with a bright 1.3″ AMOLED screen—nearly as crisp as the Teric’s, but smaller and lighter  .
• Includes air integration (up to four SWIFT transmitters) and a digital compass—just like the Teric, but trimmed down for sport divers  .
• Four-button control with intuitive menus; haptic warnings available  .
• Battery provides about 20 hours of dive time, plus wireless charging  .
• Ideal if you value a sleek form factor and don’t plan to do trimix or closed‑circuit diving.

Shearwater Peregrine TX

• Offers a much larger 2.2″ backlit LCD screen—excellent visibility even in low-light conditions  .
• Includes air integration for up to four tanks and a built-in compass  .
• Robust wrist console design, still comfortable despite its size  .
• Same 30‑hour battery life and wireless charging base as the Teric, plus USB‑C charging  .
• Slightly less vibrant display than the Teric, but its clarity and size make it a standout for those who prefer larger readouts  .

Which Should You Choose?

• Choose Tern TX if you appreciate the Teric’s form and simplicity, want air integration and compass, and prefer a lighter, more everyday-watch-like size.

• • Opt for Peregrine TX if you prioritize screen readability above all, even at the cost of bulk—and still want top-tier air integration and battery performance. Reddit users note:“…the Tern TX is everything you could want from a rec version of Teric…”  “Peregrine TX … larger screen is easy to see… very intuitive programming.”
