TZT 2 Internal Sonar Transducers

[Quitsa]

Have you tested a B175-HW with the internal sonar circuit of the TZT 2? I know that it would not be able to provide the bottom discrimination or Accu-fish being a non-diplexed single frequency transducer, but would it work otherwise as a 200Hz 1kW transducer plugged into the transducer port?

Quitsa,
I haven't heard or seen of any testing with the TZT2/175 combination.

Thanks, I have B175HW on board so I guess I can experiment and see how it works and post a screen shot. Not clear what to use for settings but I will try manual and 1kW.

But one question that I hope you can answer: if the internal TZT 2 sonar is not selected as the source and a transducer is plugged in, would it still be transmitting? There isn't any way to stop TX of the internal sonar after selecting the DFF1-UHD as the source since once the selection is done, the TX on screen menu button is controlling the DFF1-UHD.

Quitsa,
I tried this a couple of weeks ago by connecting a DFF1 and DFF1-UHD up to my TZT2 unit. I found it is possible that you can have all three transmitting at the same time which can create interference problems. Since you can only look at one sounder module at a time you need to put the unused sounder module(s) into a Stand-By condition. It's easy to do.

Thanks.
If I understand you correctly, when the internal TZT 2 sonar is selected as the source and I put it in standby, it will stay shut down if I then change sounder source to the DFF1-UHD.

I have two TZT 2 displays so I actually could display the DFF1-UHD on one MFD and have the other one show the internal sounder. I can do a little experimenting and see whether there is an interference issue.

Quitsa,
Your understanding is correct. When you start to experiment I would start with both Interference Filters off and then raise them. If you are in really shallow water you still may see some interference no matter how much IR you use.
