SKIPPER ETT985 tester for echo sounders

Part Number: ETT985-SASW

SKIPPER ETT985 is a simple to use, reliable and accurate tester for most echo sounders. Pre-programmed with factory tests for transducers, echo sounders and NMEA ports. This unit can be used in a stand-alone mode, or using a connection to a PC to give accurate results. It may even print/save a status report. The ETT985 eliminates uncertainty of whether a failure is in the transducer or in the echo sounder.
