Suunto Tank POD The Suunto Tank POD is a wireless tank pressure transmitter that allows you to view current tank pressure with just a glance at your wrist. The Suunto Tank POD is cleaned for oxygen service for added safety when diving with enriched air. The pairing procedure is very intuitive; just pressurize the system, hold your Suunto D5, Suunto EON Steel, Suunto EON Steel Black or Suunto EON Core close to the Tank POD and after a few seconds a menu pops up on the screen showing the serial number, battery status and the tank pressure.
