Operation
Your metal detector has four operation modes: DISC, TONE, ALL METAL and
TARGET TRACK. DISC and TONE are motion modes while TARGET TRACK is a
non-motion mode.
When searching, generally set "DISC" as the operation mode, with high
sensitivity and "DISC/TONE" set to "0". Sweep your search coil as demonstrated
in the picture below, moving the search coil back and forth in an arc. To ensure
you don't miss targets, keep the distance from search coil to the earth about 1 –
5cm (closer to the earth for smaller target) and the distance between two
neighboring arcs 10 – 15cm.
If there is a sound of "di-di" during moving, it indicates that there is a metal target
in the sound area. In this case, you can use "TARGET PINPOINTING" to pin-
point the target. Then use "DISC" or "DISC/TONE" to determine whether the
target is worth digging out. The followings are the four operation modes in detail.
