EDIT FERROUS LIMITS FOR SPECIFIC TARGETS

The Ferrous Limits can be edited to include or exclude specific targets, allowing you to:
Hear 'good' ferrous targets such as relics or ferrous coins that are produced by some countries, while rejecting directly
ƒ
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 >
3. Press to select the Custom Ferrous Limits you
/
want to adjust, then press the Right Soft Key (
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�
5. Press /// to navigate to the Region nearest
to the coin's Trace and then press the Right Soft Key
( Edit)�
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�
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�
