Ferrous Limits
(Continued)
EDIT FERROUS LIMITS FOR SPECIFIC TARGETS
The Ferrous Limits can be edited to include or exclude specific targets, allowing you to:
ƒ
Hear 'good' ferrous targets such as relics or ferrous coins that are produced by some countries, while rejecting directly
adjacent ferrous trash�
ƒ
Reject difficult ferrous targets that are falsely detected as non ‑ferrous�
Edit Ferrous Limits to Find 'Good' Ferrous Targets
1. Place your test target on the ground in a
metal‑free location�
2. Navigate to: Settings > Ferrous Limits
3. Press

/

to select the Custom Ferrous Limits you
want to adjust, then press the Right Soft Key ( Edit)
to open the Editor�
4. Swing the Coil over the test target — in this example, a
ferrous Canadian 10¢ coin was used� The Target Trace
will appear on the ID Map�
The Target Trace of a 1998
Canadian 10¢ coin�
5. Press  /  /  /  to navigate to the Region nearest
to the coin's Trace and then press the Right Soft Key
( Edit) �
The Region nearest to the coin's
Trace selected for editing�
6. Wave the Coil over the coin at a range of heights,
adjusting the Ferrous Limits until all of the Target Trace
is captured inside the white area�
To be thorough, you can also change the orientation
of the test target a few times in between swings to
capture any Trace variation for that target�
The coin Trace notched out of
the surrounding Ferrous Limits�
7.
Press
( Back)
to return to the top‑level of the Editor�
8. Repeat the process with different coin denominations
until you have your final Ferrous Limits pattern�
You will now detect ferrous coins directly adjacent to
ferrous trash, with the audio sounding the same as
non‑ferrous coins with the same ID�
Targets with similar ferrous characteristics to the coin,
but with different conductivity characteristics will still be
rejected�
The Target Trace of a 1998 Canadian
10¢ coin (accepted) and a directly
adjacent nail (rejected)�
