Multi Kruzer Frequencies

[Jacza]

Hello,

I made a quick air test and observed, that 5 and 19 kHz seem not to have as much power than 14 kHz. I expected that 19 kHz is better on small objects and 5 kHz better on large objects, but the performance dropped significantly for all (see photos). My setting was 4 tone mode with gain 90.

Does anyone made similar observations or is the air test not meaningful? I had also permanent disturbances maybe because of EMI except for 3 tone mode, which was stable up to gain 99.


4 tone, gain 90, 14 kHz


4 tone, gain 90, 19 kHz


4 tone, gain 90, 5 kHz

Here are also some air tests for the other modes in 14 kHz, especially deep mode was very astonishing:


3 tone, gain 99, 14 kHz


deep mode, gain 90, 14 kHz


2 tone, gain 90, 14 kHz
