The Teric dive computer incorporates the powerful Shearwater Research feature set in a wristwatch sized form factor. The Teric supports up to two optional wireless transmitters to display the cylinder gas pressure without the use of hoses. A wireless transmitter is NOT included but available as a separate option.

The Shearwater Research Teric is a full technical dive computer with recreational divers in mind. Out of the box, the Teric includes open-circuit and closed-circuit Air, Nitrox and Trimix mixed gas functionality along with a three-axis tilt-compensated digital compass. It has Recreational, Gauge, OC Tech and CC/BO modes with up to 5 Air, Nitrox or Trimix gases. It also has a new Freediving Mode with configurable sampling/ logging rates and ascent/descent indicators suitable for freediving.

The Shearwater Teric has been designed with a wireless rechargeable battery and includes a wireless induction charger stand. The expected life of the built-in battery is five (5) years and the battery can be replaced at one of the Shearwater factory authorised service centres. Although Shearwater recommends using their charging stand, the Teric can also be charged by the flat mats that support the Qi wireless charging standard (which includes the latest iPhones and many Android phones).

What's in the Box:

Included with every Shearwater Research Teric are black silicone 22 mm wrist strap with buckle plus extender (for drysuits), zippered travel case, wireless charging stand and cable (USB-A), USB Bluetooth adaptor, printed Quick Start Guide with instructions for downloading the full manual and software from the Shearwater Research. Shearwater supplies the Teric with a zippered 'travel' case.

Recreational Open-Circuit Features

Key features of the Recreational Open-Circuit mode (aka Recreational Nitrox mode) include a simpler menu structure, less cluttered display with a larger font and configurable bottom row, optional safety stops, and a no-decompression limit dive planner. The simplified settings allow for three breathing gas mixtures (Air or Nitrox) and place a greater emphasis on the maximum operating depth (MOD) and no decompression time limit (NDL). The display prominently warns the diver if their depth is near, at or exceeds the MOD of the selected breathing gas. Optional safety stops are user-configurable to be 3, 4, 5 mins or adaptable. When using the Adapt setting, a 3-minute safety stop will be used, unless the dive exceeds 30 metres (100 ft)or the NDL falls below 5 minutes, in which case a 5-minute safety stop is used. If the diver exceeds the NDL and requires stops, the display turns red and warns "DECO STOP" with the mandatory depth and stop times.

Differences of Teric vs Perdix Dive Computers

Diving watches have traditionally been perceived as being less capable or having poorer information display as a result of compromises for size. That's no longer true with the Shearwater Teric. Other than the obvious difference in size, the Teric includes several other features not found on the Perdix:

  • AMOLED display — vivid, bright colours reminiscent of the Predator.
  • Haptic (vibration) and audible alarms — can be disabled to minimise annoyance.
  • Scratch resistant Sapphire Crystal screen — along with stainless steel bezel protected with a vapour deposition process that uses plasma to embed carbon particles into the bezel for an elegant and durable finish.
  • Four button situational adaptable logic menus — also configure one of the 4 buttons to give you one press access to certain dive or watch tools like compass, stopwatch, deco planner, log tagging, etc.
  • Blue, Green, Pink, White, Yellow — dual colour wrist bands are options and standard 22 mm watch strap size makes many 3rd party options available.
  • Wireless Charging of the battery — users have no need to open the watch reducing chances of flooding. This also eliminates the risk of damage from a leaking depleted battery.
  • Timepiece mode — the Teric can be comfortably worn your wrist as a stylish daily timepiece.
  • Free Diving mode — ascent and descent indicators suitable for free diving along with configurable logging intervals as short as 1 second.
  • Home screen options - Instead of a mini compass on the home screen you can have a North Arrow moving around the outer edge of the watch face. You can also customize tissue graphs to appear on the outer edges of the home screen during the dive.
