TRANSDUCER EXCHANGE 
 
Other transducers are available as replacements for the standard transducer. 
You may exchange your new and unassembled transducer for another type by 
returning it to the address listed in Customer Support. Some transducers may 
have additional cost. Refer to the Accessory catalog or call Customer Support for 
information.
