13.9 Dual Sonar Head
13.9.1 Dual Head Installation
The R2Sonic family of multibeams can be installed in a dual head configuration, either pointing
inwards or directed outwardly, depending on the customer’s survey task. In dual head mode, the
individual sonar heads can either ping simultaneously (with frequency offset) or alternate pings
(same frequency). The dual head configuration is comprised of two sonar heads and either one or
two SIM boxes and one Sonic Control 2000.
The same exact head firmware must be installed on the
sonar heads in order for Sonic Control to operate the sonar heads .
