Dff3d & Pbg with scx 20

[Angler2184]

I have had the dff3d installed for the last 2 years but just added the scx 20 hoping it would help smooth out the PBG. When I installed the Scx 20 i went and adjusted the offsets and have attached some pictures. After putting the offsets in it still doesnt seem as smooth as others that I have seen. When using the Pbg i can still see it mapping the swell as part of the bottom.

When I put the roll/pitch offsets in under the scx20 menu, should it show the same under the transducer roll/pitch sensor offset? thanks

Angler2184,

I would recommend that you find the exact center reference point of the vessel and then carefully measure from that point to the exact center of the sensor (i.e. Transducer, SCX20, etc.). The more accurate that you can make it, the more accurate the DFF3D will generate the PBG.

The sensor time synch may need adjustment. Check and see what the instructions say for the TZ3.
On a computer, they are supposed to be set for 250ms for nmea2000.
