simrad S5100 sonar module brand new

 Simrad S5100 sonar module, brand new never used can be used with any chirp transducer compatable with the unit multi channel priced to sell $1700 well below the recomended retail with australian warranty. Obtained as a replacement for the previous  BSM 2/3 simrad module as an upgrade. I have no use for it as i bought another system prior to the upgrade offer from Navico.
