The utility provides a convenient method to collect at specified intervals field observations, such as soil samples and measurements made by field sensors such as depth sounders
, chemical detectors and magnetometers.
0 includes support for many more devices such as laser rangefinders, gas detection equipment, hydrographic depth sounders
and salinity sensors.
