RE: [TG11] Showing Manual Sonar Frequencies
Hello Fish On,
Our systems don't show what specific frequency you're operating on, when you do a manual frequency adjustment like this. I believe that the adjustment is a percentage of offset between the centre end upper or lower limit of your transducer's supported frequency range (so, for example, the B265LM supports 85-135kHz in the Medium band, so -50% offset would be 85kHz, +25% would be ~122kHz). I say 'believe' though because this isn't something we recommend or encourage and so don't spend a lot of time looking at this capability. CP570 and Axiom Pro RVX are both Chirp fishfinders, and do their best job when allowed to use their advanced Chirp signal processing to enhance detail and target separation, improve resolution, increase pulse-lengths and therefore transmit more power into the water, and reject noise. By setting your sounder to 50, 200kHz or any other manual frequency you are turning off all of that advanced signal processing capability and turning your CP570 into a something very close to a CP370. The CP570 will produce its best results and clearest images in all-Auto sensitivity setup, in Low/Medium/High Chirp band. To answer your last question, yes, you can set up multiple different fishfinder channel presets with different configuration (we just wouldn't recommend that that configuration included non-Chirp frequency setup.) The way that you do this is:
