[CA] Wi-Fish give the wrong temperarure reading

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum eghphoto,

The reported problem may be caused by either a failure of the transducer's thermistor or a failure within the Wi-Fish's circuitry. Technicians would typically fault isolate such problems by testing the Wi-Fish with a transducer which was known to be operational ... the cost of a replacement DownVision transducer is very close to that which the Repair Center would charge to bench test a product. Accordingly, for products which are out of warranty, it may be most expedient to purchase a new transducer to perform this fault isolation oneself. Should the product be in warranty, then it would be recommended that the transducer and Wi-Fish be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
