[QUOTE="Balmain Bob, post: 332906, member: 739"] Hi Jason, Blanking out is when the detector goes over a large bit of metal and the signal overloads the machine and creates a very high pitched sound that will blow your head off if you use headphones. Threshold the the background noise that the detector will always pick up , the threshold button is like a fine tune button. You need just able to hear the background noise when detecting to be able to hear the faint signal. If the background noise is too loud you may miss the faint signals. Discrimination is the ability for the detector to cancel out certain metal that it goes over. Generally not a good idea to use when detecting for gold as you should dig every signal you get. discriminationis good when using the 705 on a beach tocanel out ring pull , bottle caps etc but you may also miss out on good thing ring, watches and coins by discriminating , its not perfect. Hope this helps Bob [/QUOTE]
