Can the TERN take me through my diving career?
The TERN is designed for sport and light technical diving. If you anticipate progressing to technical diving in the future, you should consider the Teric or Perdix 2, which offer advanced functionality.

Does the TERN have smart watch features?
The TERN offers basic watch functionality and great looks. We do not include hybrid smart watch functions. We believe that reliable and intuitive instrumentation underwater is critical to your enjoyment and safety.
-
Does the TERN have audible alarms?
No. The TERN comes with a powerful customizable vibration alert system.
-
What is the screen lens made of?
The TERN features an alkali-aluminosilicate toughened glass lens that is resistant to scratches and boasts excellent transparency and impact resistance. Nevertheless, we recommend using a screen protector to maintain the TERN’s pristine appearance.
