Shearwater Peregrine vs Teric: Which Shearwater Should You Buy?

Shearwater makes two computers most recreational divers actually cross-shop: the Peregrine and the Teric. They run the same decompression algorithm, sync to the same app, and share the same menu logic -- so the choice between them is not about trust or accuracy. It is about form factor, screen technology, feature ceiling, and roughly a two-to-one difference in price. This comparison is built from manufacturer-published specifications and the consensus on ScubaBoard and owner forums, not a staged hands-on test.

The short version

The Peregrine is a dedicated wrist computer with the biggest readable screen in its class, around $450, and widely available online. The Teric is a watch-sized computer you can wear every day, with a brighter AMOLED display, built-in air integration and compass, and full technical gas support, at around $1,000 and up -- sold through authorized Shearwater dealers. Both run the same math. The decision is ergonomics, features, and budget.

What they share

The two computers agree on the parts that matter for trust. Both run Buhlmann ZHL-16C with gradient factors, both sync dive logs to the Shearwater Cloud app over Bluetooth, both charge wirelessly, both receive free firmware updates, and both use Shearwater's clean, shallow-menu interface with plain-language labels. On an identical dive with identical settings they present the same no-decompression information. Because the internals agree, there is no accuracy difference to weigh -- which is exactly why this comes down to the hardware wrapped around the algorithm.

The screen: transflective versus AMOLED

The Peregrine uses a large transflective color LCD. Transflective screens use ambient light, so they grow more legible as the water brightens and sip very little power -- ideal for a dedicated computer that lives in a gear bag between trips. The screen is big, high-contrast, and the single most-cited reason owners choose it.

The Teric uses a compact AMOLED panel: brighter, richer, and gorgeous on the surface, but smaller and more power-hungry. You are trading the Peregrine's readability-per-dollar for the Teric's vivid, watch-sized display. Neither is wrong -- they optimize for different things.

Size and everyday wear

This is the fork in the road. The Peregrine is unapologetically a dive instrument: large, easy to read, and something you put on for diving. The Teric is watch-sized, takes interchangeable straps, and is comfortable enough to wear all week as an everyday watch with notifications and activity tracking. If you want one device on your wrist every day, that pushes hard toward the Teric. If the computer only comes out when you dive, the Peregrine's size is pure upside rather than a compromise.

Features: air integration, compass, gas range

The base Peregrine has no air integration and no digital compass. Shearwater's answer is the Peregrine TX, which adds transmitter-based air integration and a compass at a higher price -- so if you want tank pressure on your wrist, you buy the version that has it rather than planning to retrofit.

The Teric includes wireless air integration, a digital compass, and vibration alerts in the box, and it carries the full technical gas range -- nitrox, trimix, and gauge modes -- so it doubles as a computer you can grow into if your diving turns technical. For a recreational nitrox diver, none of that is required. For a diver who wants integrated features now or headroom later, the Teric already has them.

Price and where you buy them

The Peregrine runs around $450 and is widely available, including online -- you can check the current Peregrine price to see where it sits today. The Teric runs around $1,000 to $1,200 and, like most of Shearwater's range beyond the Peregrine, is sold through authorized dive dealers rather than the big online marketplaces. That is worth knowing before you shop, because you will usually buy a Teric from a dive shop, not add it to a cart.

If you specifically want an AMOLED dive watch you can order online today, the Suunto Ocean and Garmin Descent Mk3i are the mass-market alternatives, and our Garmin Descent vs Suunto Ocean comparison puts those two head to head.

Battery and long-term ownership

Both computers use sealed rechargeable batteries that top up wirelessly, which removes the flooded-battery-hatch failure mode entirely -- there is no door to leak. In exchange, battery service eventually goes back to Shearwater after several years of regular diving, much the way you budget for regulator service. Both also receive free firmware updates, so the computer on your wrist keeps improving rather than freezing at the state it shipped in. In practice the ownership experience is much the same across the two, which keeps the decision where it started: screen, size, features, and price.

Which one fits your diving

Choose the Peregrine if you are a recreational or nitrox diver who wants the most readable screen and the best value, who is fine with a dedicated computer, and who does not need air integration on day one. Choose the Teric if you want a daily-wear watch, want air integration and a compass without carrying a second instrument, or expect to grow into technical diving.

The algorithm question -- why both show the numbers they show -- is identical for the two, and if you want to understand it, our Buhlmann vs RGBM explainer covers it. Whichever you choose, dive within your training and certification; the computer is an instrument, not a substitute for a plan.

Verdict

For most recreational divers, the Peregrine wins on value. It delivers the Shearwater screen, interface, and app for less than half the Teric's price, and the only things it gives up -- watch-sized wearability, AMOLED, and built-in air integration and compass -- are conveniences rather than necessities. Choose the Teric when you specifically want the watch form factor or the integrated features and are happy to buy through a dealer.
