Low scattering strength
If there is insufficient scattering material (e.g., very clear water), the sampling volume peak will be
small or non-existent. This situation can be confused with a malfunctioning transmitter unless the
boundary is in view.
Malfunctioning transmitter
This appears as a flat response with signal strength at the normal noise level. This can be confused
with a disconnected probe or low scattering levels. Note the absence of a boundary reflection to
distinguish this from low scattering levels.
