Adding DFF-3D to Current System/ Transducer / SCX-20 Questions

[Bog_Boat]

I'd like to add the DFF-3D to my system and was wondering if it would work with my current transducer if I also added the SCX-20 compass. From my understanding one of the important aspects of the specialized transducers is the motion sensor, but as most people highly recommend the SCX-20 to add to the system, I'm wondering if I could skip the specialized transducer. Thank you in advance for any and all help, this is all a lot to wrap my head around.

Current Electronics:
TZTouch3 12"
Furuno NavPilot 300
Airmar B265lh hooked up to TZT
(Old B60 12 still installed)

You need the special transducer. And it needs to be mounted where the keel won't be in the 120 degree beamwidth.
The SCX20 is an improved motion sensor and you need heading to make recording work with DFF3D, which the SCX20 also provides. Even if you don't get DFF3D right away, the SCX20 will improve your autopilot function.

Ok thanks. Was hoping to find a work around. I don’t use my autopilot for much more than navigating in wide open waters so I’ll probably hold off on the SCX-20 until I’m ready to do the whole system. I do a ton of bottom fishing so the DFF-3D has my attention.

SCX-20 is amazing, cleans up the sounder with super accurate pitch, roll, and heave information. Big difference for bottom fishing. Besides the AP, also cleans up the overlay on the Radar. I found it very worth the $$.
