B.Caps rejects the
rusty
beer and fizzy drink bottle caps effectively. Make sure you acti-
vate it on the beach, in parks and polluted zones. B.Cap reject also assists with rejecting
some types of iron which is usually difficult to discriminate, such as ferrous cartridges,
ferrous rings and some larger mis-shaped ferrous.
Adjust the rejection from 0 to 5 with

.
Targets processed by the B.Caps parameter are reported as ferrous targets so it is possi-
ble to adjust the iron volume to make them quiet.

The Notch complements the discrimination: it enables a "target window" to be rejected
whereas discrimination rejects all targets below a selected threshold. For example, if you
detect an undesirable target in the ground, you can decide simply to reject the corre-
sponding conductivity group and continue to detect targets with a conductivity higher or
lower than those in the rejected group.
If the reference target has a conductivity of 37, adjust with + and - the Notch at 37-37. All
targets with this conductivity will then be silenced.

This advanced notch function enables you to widen the rejection window in the event
that the undesirable target(s) have a fluctuate conductivity. For example, if the undesira-
ble target is generating an ID ranging from 28 to 46, you can use this option to lower the
value of Threshold 1 to 28 and increase Threshold 2 to 46.

If several targets with different conductivity levels are a problem, you can activate two
other notches: N2 and N3. Use
to select N2 or N3 and adjust as for N1.

the OFFSET FT feature allows the user to shift the “Full Tone” audio frequencies of
targets with a signature just above the Discrimination threshold, in order to better
differentiate them audibly from iron.
0 = no offset
5 = (default value) creates a little offset
40 = all targets above discrimination will sound with the same high tone.
