I have been a White's user for the 10 yrs I've detected and am used to their audio. I want to get a Tesoro but have read from the Tejon field test that deeper targets sound off quieter. I have bad hearing due to tank engines and loud music On the DFX there is a preference setting called modulation which allows a user to hear the deep targets as either loud or soft. I wondered if the Tejon or other Tesoros have this or will I hear the deeper targets just by turning the volume up. Thanks!
