3.3.2 Pressure Inverted Echo Sounder (Type 8302)
The Pressure Inverted Echo Sounder (PIES) is a long-life sensor logging node that measures the
average sound velocity through a column of water from the seabed to the sea surface. The transducer
is LMF directional, with a depth rating of 3000 and 6000 metres. The transponder’s pressure housing
is hard anodised and protected by a red sleeve. The sensor endcap can contain a stainless steel
release mechanism for releasing an anchor weight. The PIES is identified by a blue coloured housing
label.

3.3.3 Autonomous Monitoring Transponder (Type 8305)
The Autonomous Monitoring Transponder (AMT) has the same capabilities as the Compatt 6 with
additional capabilities to periodically log sensor readings and make acoustic baseline measurements.
The AMT has a depth rating of 3000 metres and is available as an omni-directional and directional
transducer. The transponder’s pressure housing is hard anodised and protected by a red sleeve. The
sensor endcap can contain a stainless steel release mechanism for releasing an anchor weight. The
AMT is identified by a yellow coloured housing label.
