I am trying to match a generic Transducer to an RXT - I want the dealer to enable the depth gauge function on the ECU - Is there any problem if the depth gauge doesn't work and the ECU enabled for the sensor? I don't think there would be - but would like to hear from others thanks. BTW the Airmar P79 tranducer is <$100.00 and the most common transducer around.

Thanks for any help
