Identifying your Transducer

Every Airmar transducer has a label attached to its cable, located near the top of the transducer or where the cable plugs into the back of the instrument or display. This label contains information that is helpful in identifying the transducer and locating the correct service parts for it. For most Airmar products this label will show:

• the model name
• the manufacturing date
• certain performance characteristics (i.e. the transducer's frequency)
• the Airmar part number (PN)
• a Customer Part #

In all cases it is the Airmar Part Number (PN) that is the most important number to have available when ordering parts or contacting us about the transducer.

Before calling or emailing us about parts, please make sure you have the Airmar part number from the label on the transducer cable.
