Description
Bottom Line Up Front (BLUF): SKIPPER ETT985 tester for echo sounders
Summary: The SKIPPER ETT985 tester for echo sounders is an IMO-compliant marine navigational echo sounder engineered by Skipper Electronics / Jotron to deliver reliable depth tracking from shallow coastal waters down to 1,000+ meters. Conforming to IMO Resolution A.224(VII) and Wheelmark MED standards, it features high-contrast touch displays, 24-hour depth history recording, and NMEA 0183 output for bridge integration. Backed by SEANAV Marine with pre-delivery bench testing and global dispatch.
System Overview & Operational Purpose
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.
