The transducer is labeled as Ashcroft, but I cannot locate the model number printed on the label on either the Ashcroft website or through an internet search?

The model transducer you are searching might have been discontinued and replaced by a new model, or it could be a custom model number normally sold to OEM’s and not listed on the Ashcroft website. Please contact Ashcroft with the model number, information printed on the label and a picture of the unit if possible.
