Bring on the future with Shearwater Tern!
The Tern and Tern TX build upon the success of the popular Shearwater Peregrine dive computer while borrowing a watch-like round format similar to the more sophisticated (and expensive) Shearwater Teric, making them a great addition to Shearwater's product line.
In short, the Shearwater Tern can be seen as a lightweight and thinner Peregrine version of the Teric, while the Tern TX additionally draws on the air integration and digital compass functions of the Perdix 2.
But neither of these models has OC mixed gas technical and CCR modes, which, for their price point, should make them a hit among recreational Air and Nitrox divers who, in the majority, do not need those modes.
Designed and built in Canada, The Tern & Tern TX are depth rated to 120 metres and tested to engineering EN standards for dive computer compliance.
They both support Air, Nitrox, 3 Gas Nitrox, Gauge, and Freedive modes. They can log 500 diving hours and have a battery life of 20 hours with dive mode on.
We're so excited by the launch of the Tern models that promise to be very popular, we've already placed a large pre-order from Shearwater for stock.
You can also pre-order your unit for the January 2024 market release and be among the first to get it by following these links:
With a watch-style form factor, the 1.3” diameter AMOLED screen provides crystal-clear visibility in various lighting conditions, making it easier than ever for divers to keep track of their crucial information.
The vibrant, best-in-class high-resolution display offers Shearwater’s renowned user interface that provides divers with at-a-glance access to vital data, ensuring a safer and more enjoyable diving experience.
The Tern and Tern TX Compared
What’s identical in both models are:
- They are both compact, stylish and lightweight, thinner than the Teric
- They support Air, Nitrox, 3 Gas Nitrox, Gauge, and Freedive modes
- Their battery life with dive mode on is 20 hours
- They are charged wirelessly and support quick charge
- They have Bluetooth
- They have haptic alarms
- They have vibrant clear 1.3″ Amoled colour screens & toughened glass
- They are depth rated to 120m
- They have 500 hours dive log
- Both are available with the new Shearwater Remora quick-connect straps
While the bezel and buttons of the Tern are silver colour they are black for the Tern TX.
The Tern TX Difference
In addition to all of the above, the Tern TX has two fundamental functional differences to the Tern.
- It is transmitter-enabled to provide real-time gas pressure readings during a dive
- It has a digital compass for underwater navigation
Simply put, the enhanced Tern TX boasts air integration similar to the Shearwater Perdix 2 and is capable of connecting with up to four Swift gas pressure transmitters as well as having a digital compass for superior underwater navigation.
As mentioned above, the Tern models look like a thinner and lighter version of the Teric but are more of a Peregrine regarding functionality. The TX model adds gas monitoring integration and a digital compass into the equation.
Neither the Tern nor the Tern TX support OC technical (i.e. five gas) or CCR & CC bailout modes, which most sport divers do not need or use.
Shearwater TERN or TERN TX?
While both units are watch-style like the Teric, it is worth noting these are thinner and lighter than the Teric and are ideal recreational dive computers you can wear all day, anywhere.
Suppose you already have a transmitter or will consider purchasing one now or in the future for real-time gas consumption monitoring (with the additional benefit of a digital compass). In that case, the higher-priced Shearwater Tern-TX is the one to look for.
If you trust your existing compass and SPG gauge and are comfortable using both, the cheaper Shearwater Tern would be an equally good purchase.
We're excited to see Shearwater continue to push the boundaries of dive computer innovation with these two new wearable computer models.
These computers are sure to be a hit with recreational divers of all levels looking for a reliable, feature-rich, and stylish dive computer they can wear all day and dive.
If you love the Shearwater Peregrine Dive Computer as much as we do, you’ll love the Tern and Tern TX!
