Since 1941 Hans Hass used bag-on-back rebreathers originally built by Dräger for self-rescue of submarine crews (Tauchretter, like the Davis Escape Set).
Back in Lübeck he was enrolled in the workforce at the Drägerwerk AG.
In 2001 the PLMS Pulsar, soon afterwards acquired by Dräger as their Polytron Pulsar, was the first detector to incorporate sensing to monitor the mutual alignment of the transmitter and receiver during both installation and routine operation.
The pilot navigated via a wrist compass and air was provided through a Dräger self-contained breathing device.
