Mounting at the aft end of a shoe
Hydrophones can be mounted at the after end of a transducer
shoe for an echo sounder or other underwater acoustic
equipment. The distance between the hydrophone and such
equipment must not be less than one meter and the greater the
separation, the better. Installing a hydrophone in close proximity
to underwater acoustic equipment can reduce system
performance due to interference.

The illustration shows a PI hydrophone installed aft of an echo
sounder arrangement for one or more transducers and/or other
underwater acoustic equipment. Note the minimum allowable
distance between the PI hydrophone and the other equipment.
As with other mounting options, hydrophones mounted at the
after end of a transducer shoe must have an unobstructed
line-of -sight to the sensors attached to the trawl.
