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 robust digital communications technology brings not only improved stability but also new features such as multiple tank pressure readings. The reworked pairing procedure is very intuitive; just pressurize the system, hold your Suunto D5, Suunto EON Steel 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.
