Discontinued Models

This page lists transducer models that have been discontinued by Airmar since 2010.

Models may be discontinued for a number of reasons: the launch of a new model that replaces the functionality of an existing one; difficulty in sourcing a crucial component; or a lack of market demand.

Parts for discontinued models are often produced for many years after the model is withdrawn since all Airmar transducers have a very long service life.

Versions were available with connectors for ST50, Cetrek 2-Pin, RCA, Garmin 6-Pin, Bare Wire, Generic 3-Pin and Raymarine ST40/60.
B271W The B271W was a through-hull wide-beam transducer with fairing, and was the same physical size as the B260.

It operated at 200kHz only, with a beam width of 25° and a power rating of 1kW.

The B271W was a Mix and Match transducer and could use any 1kW M&M cable.
CA500 The CA500 was an underwater video camera in a transducer housing.

It used the plastic P617V, bronze B617V or stainless SS617V housings.

Versions for PAL (Europe) and NTSC (US) video formats were available. The CA500 used a 1/3" Sony CCD and had a resolution of 510x492 in NTSC, with a 92° angle of view.
P48W The P48W was a transom-mount wide-beam transducer made for Raymarine A-series equipment. Raymarine sold it as part A102140.

It operated at 200kHz only, with an ultra-wide beam of 38°. Its power rating was 100W.

Only one version was made, with the '-RAYA' connector.
R209 The R209 was an external-mount broadband 2-3kW transducer with a selectable frequency.

It operated at any frequency between 33kHz and 60kHz in the low band, and any frequency between 130kHz and 210kHz in the high band.

The R209 was a non-diplexed transducer made for the Raymarine DSM400 and for Furuno non-diplexed sounders.
R299 The R299 was an in-hull broadband 2-3kW transducer with a selectable frequency.

It operated at any frequency between 33kHz and 60kHz in the low band, and any frequency between 130kHz and 210kHz in the high band.

The R299 was a non-diplexed transducer made for the Raymarine DSM400 and for Furuno non-diplexed sounders.
R309 The R309 was an external-mount broadband 2-3kW transducer with a selectable frequency.

It operated at any frequency between 25kHz and 45kHz in the low band, and any frequency between 130kHz and 210kHz in the high band.

The R309 was a non-diplexed transducer made for the Raymarine DSM400 and for Furuno non-diplexed sounders.
R399 The R399 was an in-hull broadband 2-3kW transducer with a selectable frequency.

It operated at any frequency between 25kHz and 45kHz in the low band, and any frequency between 130kHz and 210kHz in the high band.

The R399 was a non-diplexed transducer made for the Raymarine DSM400 and for Furuno non-diplexed sounders.
SS258 The SS258 was a stainless-steel version of the B258 through-hull transducer with fairing.

It operated at 50/200kHz and had a rated power of 1kW. The SS258 could also be used with 600W sounders.

The SS258 was a Mix and Match transducer and could be used with any 1kW M&M cable.
SS264W Pair The SS264W pairs consisted of one SS264W 50kHz transducer and one SS264W 200kHz transducer.

Both transducers had identical wide 25° beams.

Versions were available for Furuno 10-Pin, Furuno non-diplexed, Garmin 6-Pin, Geonav 8-Pin, Lowrance/Simrad 7-Pin, Raymarine DSM300, Raymarine DSM400, and Si-Tex 8-Pin.
TM270W The TM270W was a wide-beam, transom-mount transducer with the same internal components as the SS270W.

It had 25° beams at both 50khz and 200kHz.

The TM270W was a Mix and Match transducer and could be used with any 1kW M&M cable.
