It depends on ground mineralization levels. I have taken a Gold Kruzer to sites where I had to turn sensitivity way down so it wouldn’t overload. On the same site I could run the Nox 800 in Gold 1 or Gold 2 Multi (which includes 40 kHz as one of its simultaneous multi frequencies) at much higher sensitivity without it overloading. So 40 kHz single frequency vs 61 kHz single frequency is not the only factor. The 800 being able to handle the ground conditions much better using its Multi IQ tech is what makes the biggest difference. The same happens with the simultaneous multi frequency Nokta Legend vs the Gold Kruzer even though the Legend like the 800 only has 40 kHz for its highest simultaneous multi frequency.
