Airmar’s external diplexer boxes allow dual-transmission-line Transducers to be converted for use with the single-transmission-line sounders.

The DIPLEX-MM can be used to convert a dual-transmission-line Transducer from BBFF3 or DFF3 into a single-transmission line for use with Furuno, Garmin, Simrad, Navman, Northstar, Lowrance, Si-Tex, and other fishfinders. The original Transducer cable is wired to a terminal strip inside of the diplexer box and retained via a strain-relief compression fitting.

Airmar’s 1 kW Mix and Match cables attach to the output of the DIPLEX-MM box, converting the dual-transmission-line Transducer for use with all sounder brands except for Raymarine.

Mix and Match cable sold separately.
