DFF-1 Upgrade

[Fishcakes101]

I currently have a Navnet 3-D system with a DFF-1 sounder and an Airman B744V transducer. With 2 MFD 12 screens. I would like to upgrade to the new DFF-1UHD sounder and a new chirp transducer this fall. Will I notice a markable difference in making this change ? Thank you for any advice

The NN3D system is older and doesn't support the DFF1-UHD. Someone might be confusing it with the BBDS1 or DFF1 that you have.
