Airmar DIPLEX-MM External Diplex Box

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

For example, 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 DIPLEX-RAY is used for converting a dual-transmission-line transducer for use with Raymarine sounders only. 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.

The DIPLEX-RAY includes a Raymarine 1 m (3’) cable pre-installed, for use with DSM30, DSM300, and other Raymarine sounders.
