Five Rules Shearwater Broke With the Teric

These are five rules we ended up breaking when we brought forth the Teric.

1. The Letter “P”... sort of

There is a tradition for Shearwater wrist worn computers to have their names start with the letter “P”. The Teric breaks this rule... somewhat. Teric is derived from the word Pteric, as in Pterodactyl or Pterosaur. The word Pteric means “of, relating to, or resembling a wing”.

We decided to break this rule and went ahead and removed the silent “P”. In doing this, we hope to avoid countless spitting contests that may have arisen from people misinterpreting the pronunciation of Pteric.

2. Shearwater Computers are NOT to be worn in weddings above the water surface

Many readers will agree with me that a Predator dive computer is a beautiful thing. Unfortunately, society would frown on me if I showed up to my cousin’s wedding in a 3 piece suit and sporting my beloved Predator. The Teric breaks this rule in way most gracious to society. A Shearwater can now be elegant everywhere. I might even get away with wearing it on my right wrist always.

3. You can have any color as long as it's black

Black is cool. Black means business. No futzing around. The best fins are black. The best wings are black. And we’ve heard from a reputable source that black cars look better in the shade1. Until now, the best dive computers were black. The Teric unceremoniously breaks down this rule. Shearwater now offers the Teric with five optional watch band colors, including Shearwater blue and, more importantly, hot pink.

Furthermore, the Teric was designed with a standard 22mm strap size. This means that a plethora of watch band options are available from third party vendors. Personally, I’m in the process of mounting my Teric on a cobra stitched paracord bracelet for ultimate coolness. If the paracord works out, I might cobra stitch me a bungee cord bracelet.

4. Computers with highly visible displays have to be big

The first Shearwater computers were massive stainless steel boxes. CCR models with heavy cables coming out of them that could be swung around and used as medieval morningstars in case of emergency.

Later on, the box got smaller and the screen got bigger. Currently, many Shearwater users are appreciative of the degree of visibility they can obtain from our computers. Now the Teric is coming to break down the rule that dictates that computers with big numbers have to be in big boxes. The Teric is highly configurable and one of the configurable options is what we call the “Big Layout”. Critical numbers in this layout are maximized, optimizing the usage of the Teric’s compact size for those of us with less than perfect eyesight. Big Layout in the Teric’s vivid AMOLED color screen is not easily missed.

5. Shearwater doesn’t have a freediving mode

Does too! Well, now it does. In the process of breaking this rule we had to break other rules as well. As Shearwater divers we have, from an early age, grown to develop a aversion for annoying beeping alarms that could not be shutdown underwater. On the other hand, we recognize that freedivers find audible alarms genuinely useful. So we included an audible alarm that can be disabled. But wait, there’s more! We also included a haptic (vibratory) alarm that will be less annoying to other sea creatures in the vicinity.

We also increased the sample rates and made these rates configurable. In this way, freedivers can get a better resolution on their divelogs.

Overall, we are very pleased with the Teric. It comes with all the features that divers have come to love in Shearwater computers and then some. We believe it embodies the best qualities of the Shearwater DNA in its next evolution.

  1. Very interested in this computer.
    Is it the algorithm or software as the Perdix ?
    Is this watch light weight, also can you turn off water activition for computer to use for swimming as well when teaching in a pool

      Hi, Peter. The Teric weighs 120.4 grams. It does use the same Buhlmann GF algorithm that is loaded on the Perdix. Our stand alone computers are not activated by water, but rather by pressure changes. If a dive starts up while in the process of swimming or teaching, you can choose to end the dive with a few button presses.

      I have the real big Shearwater. I wear it on the surface as well as diving. Is there a function that would provide larger watch face?

      • Shearwater Research Shearwater Research

        There are currently 3 watch faces available: Digital, Analog and Orbits. Each of these can have 3 different information levels. Over 100 possible watch face appearances can be created by selecting the watch
        face, information level, and watch face color. The AMOLED display makes it very visible. It lacks nothing in terms in visibility when you compare it to our other models. Cheers.

    Congratulations on a great looking computer. Curious, will the ability to change sample rates be backwards compatible with the Petral 2 or Perdix?

    • Shearwater Research Shearwater Research

      Hi, John. At this point in time, the Teric is our most feature rich computer. We will continue to support for Petrel 2 and Perdix. As we roll out new firmware updates for Petrel 2 and Perdix, some of the Teric features will become available to them. There may be some physical or hardware limitations that could prevent any given feature from being implemented across all Shearwater computers. The Teric will allow us to evaluate which features prove to be more popular and useful in the eyes of our users. We can then prioritize which features are rolled out to Petrel 2 and Perdix users. Overall, we recognize the value we give our customers by adding useful features to our computers and we will strive to deliver on this front whenever feasible.

    Will the transmitter for the current AI computers work with this new one?

    Reply
    • Shearwater Research Shearwater Research

      Hi, James. Yes, The Teric uses the same transmitter that the Perdix AI and NERD 2 use. Transmitters with an FCC ID = MH8A are compatible with Shearwater Air Intergrated computers. It is common for transmitters to have their FCC ID etched somewhere in the body of the transmitter.

    Does the Teric have anywhere that a lanyard can be attached as a backup if the watch strap breaks or the pins come loose underwater? I hate trusting pins on watchstraps, especially with gorgeous equipment like that! Great looking new computer!

    Reply
    • Shearwater Research Shearwater Research

      Thank you for the kind words, Wendy. There is no purposefully designed provisions for lanyard attachments. Our watch bands and extension straps are made of shore 70A silicone that has a very nice balance between strength and elasticity. The strap, when connected to the Teric, can lift 51 lbs unbuckled and 70 lbs buckled. The lugs on the pin are set with thread locker. If you change to a different color watch band or remove the pins for any reason you can apply a drop of threadlocker on the lug for extra peace of mind. Cheers.

    First off….I am a huge fan. I have talked up Shearwater so well, nearly 75% of my students end up with a Perdix on their wrist.

    I have seen some basics only , but is there a resource available to view technical data such as battery capacity, type, wireless specifics?

    Is there a low-power watch only mode such as on many smart watches?
    Thank you,
    Mike

      Thank you for the kind words. The most detailed specs that we published are in the Teric Manual in pages 88 and 89. You can see it here: https://www.shearwater.com/wp-content/uploads/2018/06/Teric_Operating_Instructions_docrevB.pdf . We do optimize our power consumption as much as we can. When you are in watch mode many of the dive computer features are off. Some, like tissue loading tracking functions, will not be off because these are crucial for repetitive diving.

    Pity it doesn’t support VPM, I would have definitely gotten one if it did, it’s useless to me without VPM. No matter what your opinion is, why can’t you just let users choose for themselves?

    We’ve been getting great results for years over hundreds of dives using VPM (+2) over Buhlmann especially on long decos where Buhlmann is way too conservative. Please let adults make their own decisions instead of treating them like children….

    Might be being daft but can’t see how it charges? And I’m not Trimux, qualified but as I dive to ADC tables I’m assuming you can switch gases during a dive?
    Stunning looking computer. Love the appearance.

      Hello, Del. The Teric recharges through the use of its inductive/wireless charging capabilities. You can read about inductive charging here: https://bit.ly/2zb5nWh. Regarding changing gases during a dive, all Shearwater computers have this capability, including the Teric. Cheers.

    I was hoping for the same functionality as the Perdix but was surprised to see 4 buttons. That is one of the things I loved about the Perdix, the ease of use when wearing gloves. Not sure I will get this model.

      Hello, Mike. Being in British Columbia, Canada we got to personally test the Teric in our local waters. Our local diving requires us to wear heavier wet gloves (5mm neoprene is typical) or different styles of dry gloves. We were satisfied with the operation of the buttons under these conditions. Cheers.

      Hi, David. You can see a video from a diver comparing different computers during a dive here: https://youtu.be/_rlqXlP2Fik. We’re obviously biased towards our own creation, but we think the Teric is visible under sunlight. You can also search the internet for independent reviews and feedback or go to one of our dealers on a sunny day. Cheers.

    Does the teric automatically adjust for altitude dives and if so what is the altitude range it covers? Is it the stanard 20000ft? Also is there any projection on how long the rechargable batter will last before it needs to be replaced?

    Reply
    • Shearwater Research Shearwater Research

      Hi, Josh. Yes, the Teric does automatically adjust for altitude. The range goes to 500 millibar which is equivalent to roughly 18,000 ft. Please keep in mind that the operational range of our computers does not imply that diving at these altitudes is a safe common practice. There is very little data, if any, related to diving at high altitudes. Regarding battery, the typical battery life is 5 years or 500 charge cycles. The battery can be replaced at authorized service centers. If the battery is not meeting performance specifications within the 2-year warranty period it will be replaced free of charge. Variations to battery lifespan can be expected due to operating at extremes of the rated specification, such as high environmental temperatures or repeatedly fully discharging the battery.

    Hello,
    What kind of toughness testing has been done in the teric? Drop tests? Smash tests?

    If it falls off of a counter will it survive? I have seen one post on scubaboard where this happened and the screen would no longer work.

    Reply
    • Shearwater Research Shearwater Research

      Hi, Aaron. We do perform drop and smash tests. A fall from a counter should not pose major risks to a normal Teric. The case you mention likely had a defective or compromised display and the fall was just the last straw that made it break.

    Hello, RIght now I am using a Perdix with VPM. The compactness of the Teric looks exciting & promising. I sincerely hope you reconsider adding VPM to the Teric. I am convinced I am not alone wanting a Teric but waiting for VPM to be added to it. So for the time being no Teric unless VPM i’m afraid …

    To truly break rule 2 (wearing dive computer above water) does Shearwater have any plans to provide more watch face configurations? I am particularly interested in a Chronograph watch display that would really confuse above ground dwellers of the underwater capability of the Teric.
