"In two reported incidents, the exterior case of a Suunto Wireless Tank Pressure Transmitter has failed during regular dry land pressure testing. Although extremely rare, this represents a potential risk of injury due to the risk of bursting...Suunto has decided to initiate a recall of all Suunto Wireless Tank Pressure Transmitters and Suunto Tank PODs."
