I did the test after asking if it was possible because currently, to my great regret, it is impossible for me to use the hf2 coil in the places I frequent, I bought it to have greater separation in the middle of the iron but today it is impossible for me to hunt in these contexts since the iron falsifies around the tid 50-60-70... then I tried with the v2 to pair the hf2 coil and it works, it gives me the classic frequencies that I have on the black 9" one, I thought at least the shape should help me to separate better so that at least I can use it 😞
