Ferrous Limits (Continued)
Edit Ferrous Limits to Reject Difficult 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 (

to open the Editor.
4. Swing the Coil over the test target — in this example, a

of the test target a few times in between swings to
captured the any Trace variation for that target.
