There are two versions of the
DFX-7
series:
DFX-7
and
DFX-7+
. The
DFX-7
is a
wide band only gauge, which includes a single wide band filter with a range of
1.8MHz
to
19MHz
. The
DFX-7+
includes the same wide band filter, but also includes
a few narrow band filter options at
2MHz
,
5MHz
and
10MHz
. The wide band option
is responsive to all signals within the given frequency range. However, narrow band
filters eliminate signals outside of the target filter frequency, and focus on the output
of the transducer at the specified frequency. The procedure to change the
