Fish finders
Fish finders are systems ranging from small
individual transmitters for leisure boats to
professional systems used in large ships to
sound the water depth or locate schools of
fish. Piezoceramic transmitters of different
geometry and covering a frequency range of
5 kHz to 10 kHz are used in the different
systems. There are echo sounder systems
which use the same ceramic transmitter to
send and receive, but there are also the
so-called trailing sonars where the sender
and the receiver operate separately from
each other over greater distances. So-called
transmitter arrays consisting of a number of
individual piezoceramic disks which can be
controlled individually and electronically
with a time delay are assembled for large
ships. The beam can thus be deflected
electronically.
