Airmar R111LH and DFF3 - Manual Setup on TZTouch 2

[Wnoone28]

Can anyone recommend where I should set my frequencies and bandwidths? It’s a chirp transducer setup on fixed frequency.

Here are the transducer specs:
Low frequency:
38 to 75 kHz
19° to 10° beamwidth

High frequency:
130 to 210 kHz
8° to 4° beamwidth

Please see attached screen where I’m trying to adjust the frequencies.

Thanks!

Wnoone28,

You could set the DFF3's Low Frequency for 50kHz, and the High Frequency side for 200kHz to start, and then experiment with certain frequencies for certain fisheries.
