3.
Pull the two sections apart to slide the lower stem out of the upper
stem.
**
Try not to pull lower tube all the way out.
Establish Tube Length
1.
Pivot the searchcoil perpendicular to the tube.
2.
Place detector in user’s hand,
with arm extended.
3.
Adjust stem length so that searchcoil
rests on the ground, close to
the user’s feet.
4.
Align the searchcoil so it is
parallel to the ground.
5.
Tighten the locking collar
while holding the

Target Identification and Discrimination
The Bounty Hunter Mach1 metal detector can both identify buried metals by
category, and eliminate unwanted metals from detection.
“Discrimination” refers to the detector’s ability to both identify targets and
eliminate them from detection. When a Target ID category has been eliminated
from detection, we say it has been “discriminated out.”
Target Identification
The Mach1 can distinguish between four categories of metal targets:
1. Ferrous:
This includes many
iron targets such as nails,
screws, bolts and some large
iron objects like horseshoes.
The Mach1 will respond with
a bass audio tone and
display the
icon.
2. Non-ferrous low conductor:
This includes many small
rings and small jewelry but
also includes many trash
items such as foil and newer
pull-tabs. The Mach1 will
respond with a low-pitch
audio tone and display
the
icon.
3. Non-ferrous medium
conductor:
This category
includes U.S. nickels, larger
rings and large jewelry but
also includes many trash
items such as older pull-tabs.
The Mach1 will respond with
a medium-pitch audio tone
and display the
icon.
4. Non-ferrous high conductor:
This includes most copper
and silver coins, as well as
modern clad coins. The
Mach1 will respond with a
high-pitch audio tone and
display the
icon.
