I have a Furuno DFF3 sonar module (up to 3 kW) and I'm going to install an Airmar R299 transducer (2-3 kW), but I'm not sure if the Furuno DFF3's configuration is correct. I'm sending you pictures; can you help me?
If you are going to utilize the R299 Transducer connected to the DFF3, then you'll need to change the Tap Settings to the following: Low Frequency is Tap "C", and the High Frequency is Tap "A".
What is the MFD that are you using to connect the DFF3 too...?
