SONARS9

In 1968 Simrad introduced the SU Sonar series, which featured a transducer deployedby hydraulics. The success ofthe SU didnt deter Simrad in working to develop a morecost-effective solution and in1975 the ST Sonar was relea-sed. It used an inflatable dome system (as an alternative tohydraulics), which created aerodynamic protection for thetransducer. Another simpleidea that demonstratesSimrads forward thinking attitude and customer commitment. The ST Sonar was mounted in a special rubber dome thatwas inflated during use.
