Many Airmar transducers are today made in a Mix and Match configuration. The basic transducer has a short (2m) cable attached and a second, longer (8m) cable is supplied which connects to the transducer pigtail and terminates in the correct connector for a given electronics brand.
If you have a Mix and Match transducer, you can switch to a different brand of electronics by replacing the longer cable. See the pages for 600W M&M and 1kW M&M cables for details.
This page links to descriptions of how to adapt from one transducer connector to another on older fixed-cable transducer designs that do not use the Mix and Match system. Select the existing connector below and click on it to see the available options.
