Is the depth indicator working differently in Discrimination and in Pinpoint?
Yes, they do work differently, because the Discrimination and Pinpoint modes operate differently; one is motion, the other non-motion, The Depth Indication must suit each. Depth in Discrimination When in Discrimination mode, as opposed to Pinpoint mode, E-TRAC is a motion detector, that is, if it is held still over a target, no detection will be registered. Just as holding a motion detector motionless over a target will quickly kill the audio signal, holding it still will also make the detector see any target as infinitely far away. The detector must be kept moving over a target for any signal to be registered, both for detection and for the measurement of its depth. Depth in Pinpoint In Pinpoint mode, the detection signal does not die away when the coil is held over a target. The Depth Indicator also responds to this ‘DC’ signal when in Pinpoint mode. However, before the Depth Indicator responds, the centre of the coil must pass beyond the target; not very far, but just far enough to
