Shearwater - Teric

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 recent introduction of the Shearwater Teric dive computer.

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 recent introduction of the Shearwater Teric dive computer.

Other than the obvious difference of the wrist-watch form factor, the Teric includes several features not found found on the Perdix:

  • AMOLED display - vivid, bright colors reminiscent of the Predator offers exceptional readability underwater along with a user configurable Big Layout display setting to enable larger fonts that can eliminate the need for "gauge readers".
  • Haptic (vibration) and audible alarms - can be disabled to minimize annoyance.
  • Scratch resistant Sapphire Crystal display window - along with stainless steel bezel protected with a vapor deposition carbon coating for an elegant and durable finish.
  • Four button situation adaptable logic menus - also configure one of the 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 color wrist bands are options and standard 22 mm watch strap size makes many 3rd party options available. DGX also offers classic NATO and Depth Compensating Slide Release wrist bands.
  • Wireless rechargeable battery – users have no need to open the body thus reducing chances of flooding. This also eliminates the risk of damage from a depleted primary battery that begins to leak acid.
  • Timepiece mode - the Teric can be comfortably worn as a stylish daily timepiece with a selection of watch faces.
  • Free Diving mode - ascent and descent indicators suitable for free diving along with configurable logging intervals as short as 1 second.

The Teric firmware currently supports only English language menus, while the Perdix supports alternate firmware loads with English and a second language choice of French, Simplified Chinese, Traditional Chinese, German, Japanese, or Korean. Shearwater Research tells us they expect to introduce alternate language firmware loads for the Teric, but no definite time frame has been established.

As of 2018, recent decompression research has called in to question the practice of "deep stops" and Shearwater Research does not recommend the use of the VPM algorithm. The Teric only supports the proven Bühlmann ZHL-16c algorithm with configurable Gradient Factors and does not offer support for the alternative VPM algorithm. The Petrel and Perdix models currently continue to support VPM as an extra cost optional alternative.
