Dual sounder data on one Display TZT3

[allrelative]

My Set up
2 TZT3
175HW Connected to one TZT3
175MW Connected to the other.
Networked together with switch, SCX20 and NMEA2K

The ask
The request or ask is, can I display BOTH transducers on ONE TZT3 screen?
I do not think this is possible, but this should be a very easy bug to fix.

I am pretty sure you can do what you want but you will need to get a Y cable or adapter and connect both transducers to a single TZT 3. There are two transducer connections in the 12 pin plug. One would be used for the B175HW and one for the B175MW.

If you have the transducers connected as you have them now using two TZT3s, you can only show one at a time on a single MFD because you have to select a "sounder source" which is one or the other TZT3.

Y cable does not work with HW & MW. Since I can view and control either transducer from either TZT3, I figured a split screen would be easy.

You can have DFF3D, Side-Scan and one sounder displayed all at once. You can NOT view two different "fish finders" on the same MFD at the same exact moment. This is the way it was designed. It is not a "Bug". There is one sounder source under the fish finder menu and that is the one it will show. If you wish to see the sounder, that setting changes to the new "source" and then you can see that one. There are no options for having two sounder sources on the same MFD. Sorry but that is by current design and been that way for all NavNet unit and all Navnet series. It is possible to see one sounder on one MFD and the other sounder on a second MFD.

Are you sure you cannot connect both to a single TZT 3? There are two transducer connections in the port. I believe the B175MW can be connected to the low frequency side of the internal sounder while the B175HW is on the high frequency side. The B175MW operates in the range of 60 to 100Hz. You may need to use the dual pigtail adapter to wire it (that's what I had to use) and perhaps input the transducer settings manually. Then you would be able to have side-by-side on a single TZT3.

Johnny was answering a somewhat different question, which relates to how you have it set up now with each transducer on a different TZT3.

Pairs with the Y cable must be a set to a selection that is programmed into the software. If that model pair setting is available then yes but I don't think that combination is one of the supported pairs in the software.
