boats hull. Survey sounders are designed to provide a large number of pings with as little
processing of the raw data as possible to define the bottom in as fine detail as possible. Of major
concern in a survey sounder is a narrow beam width to prevent averaging of the returned signal.
200/30 KHz Active Transducer
The SonarMite uses Active Transducers, these are digital as opposed to analogue components
and use microprocessors to synthesize transmitted frequencies and to interpret the return signals.
The devices incorporate state of the art DSP and filtering techniques to reduce noise and improve
depth tracking. These devices are supplied encapsulated in resin and have no serviceable parts.
The connecting cable to the transducer carries only low DC voltage and digital I/O, none of the
EMC problems associated with conventional analogue sonar devices apply.
To improve weatherproofing and to avoid connection problems the SonarMite has two
connectors that provide all the I/O required by the device. One of the connectors also includes a
return pin to enable the system to be „turned on‟ by cable connection rather than using a switch.
Cables to the device can be connected simultaneously (e.g. Transducer on port 1 and Serial Data
Cable on Port 2).
