What is the best KHz for coin shooting? I've read the lower the better for coins. I seem to like the lower kHz since the TID numbers are spread out more,instead of being jammed together,at the top of the scale. I've tried them all on the Deus,and the only thing I can say is,that I've never noticed any difference in target depth,using any of them. I know the higher frequency's will pick up smaller targets,but dose it make any real difference on coins? Also why did they (XP) decide to use the high scale(18 kHz) in ID Norm? To me (anyway) having the target ID's spread out,makes it easier to notch out targets you don't want to hear,and assign the tones to the targets you want to hear.
