MikeR13,
Thanks for the pictures.
If the two transducers on the right are going to be replaced I would mount the DFF3-3D ducer where the outer transducer (paddle wheel) was. I would get the face of the DFF3-3D the same depth as the B-258. You want to make sure that the two transducers are far enough apart that they don't pinch the water flow going between them.

So if i remove both of those and mount towards the edge of the bracket thats welded on my transom i should be ok. There would be over 3" between transducers

MikeR13,
The TM-265 and DFF3-3D transducers are pretty close to the same size and shape, about 4.25" wide. If you have them 3" apart means you will have turbulence water flow at higher speeds. As you move though the water a transducer is going to split the flow of water around it, so 2.125" + 2.125"= 4.25" of disrupted water trying to pass through a 3" gap. I understand you have a limited space to work with so do the best you can.

I can probably just weld another plate onto the transom and attach the new 3d transducer to it to spread out the distance between them. But I understand what your talking about.

Is that new DFF-3D will be compatible with NN3D in a near future?

Nick,

At this time there are no plans to integrate the DFF3D with a NN3D System.

I was watching one of the online videos from Furuno regarding the3d transducer. It was communicated that if I had a dff1 or a minimum of a 600 watt transducer I could run both that unit and the 3 d at the same time? Prior to installing my chirp that I currently use I had a ddf1 and a tm258. Would the 258 would in conjunction with the 3d? I am adding the 3d and a tzt2 to my system

Will i be able to run the 258 and the 3d at the same time? In one of the videos on you tube is says you can run another transducer on a dff1 with the 3d. Is that correct?

Mike,

With what you have available, you can do a number of different things:

1. You can run a DFF1/TM258 at the same time as the DFF3D. Matter of fact, you can have them both on your TZT2 screen at the same time.

2. You can do away with the DFF1 and connect your TM258 directly up to the TZT2 transducer port. This will also allow you to run the DFF3D at the same time. This would be my recommendation because it removes the DFF1 from your network. The DFF1 is not needed since your TZT2 already has a great sounder built in.

To make sure we are clear though, the one thing you cannot do is transmit a DFF1-UHD and DFF3D at the same time because as the DFF1-UHD "chirps" across the frequency band, it will interfere with the 165kHz of the DFF3D. You can have them both on the same network, you just have to ensure while one is in transmit the other is in STBY. This is the setup I am running on my boat and it works great. From time to time I do forget to put one or the other in STBY and you realize it right away when you see the noise on the sounder screen. When it happens, I just put one of the two units in STBY and the problem is solved.

Stickman, thanks for your information. What size fuse do you have in your 711 C autopilot? I have a 10 AMP in there now. I am in the process of hooking up the TZT2 and the dff3d. Are both your transducers transom mounts?
