F-SCAN2 is a sophisticated machine with amateurish software and user
guides. (The F-SCAN Touch is
similar to the F-SCAN2 but has a larger screen and additional
features.) What distinguishes the F-SCAN from other frequency
generators is its ability to scan the body (referred to as a
DIRP — dual integration resonance procedure) to obtain
"resonance feedback" — i.e., frequencies from which
the body may benefit, presumably representing pathogens or other
issues, which you can then output from the machine for
unit produces both sine and square waves up to 60,000 Hz and
only sine waves above that. Since
square waves are often used in rifing (for example, the F100
series models produce only square waves), some may find
their unavailability at higher frequencies a disadvantage. (It's
controversial, which is why I include it here rather than under
unit has a single output channel (three on the Touch model,
along with a carrier frequency).
Like the F165 (and
unlike the GB-4000), it has
no internal cooling fans. Also, it can produce a beep when
making entries or after operations, but this is optional.
adjustment of square-wave output level (optional; selected
with the Auto-R button), so that it's never high enough to
cause a shock. You set a maximum level before beginning, and
it doesn't exceed that. (It works only for square waves;
i.e., below 60 kHz. The sine-wave output level is constant,
according to the user guide, so Auto-R is not needed.)

at lower right
is done in the software —
whether via the touchscreen or on your computer —
so you can (theoretically, at least) set things up and not
have to intervene again until you're done.
(Practically speaking, the software doesn't always function
as intended; see the Software Issues section below.)
offset (keeping output voltage above zero — reported to be
preferable for rifing) is selectable from a menu.
sweep function is limited. You can do a sweep between the
minimum and maximum frequencies you enter in the Settings
screen, specifying the total time or length of dwell on each
frequency. Alternatively, you can sweep from one frequency
in a list to the next, but only in 1 Hz increments. You can
Wobble (converge) around each frequency, but only in
increments of 10 Hz, up to 600 Hz.
I had to press the touchscreen repeatedly to get it to
accept an input (which is one reason I found it easier to
run from the software on my computer).
cables to connect the handgrips and DIRP finger clip to the
machine are thin. The connector that attaches the finger
clip to the machine is small and delicate. Replacements are
expensive. (About $175 for the finger clip. This is the
manufacturer's list price converted from Swiss francs at the
current rate of exchange; the price from the US distributor
may be different.)
manuals for the machine and software are poorly structured
and designed and therefore confusing. Most of the
information is there; it's just presented in a jumble.
Scan Function (DIRP)
there was a dispute over the value of the
DIRP (whether it did what it claimed) and its
spurious frequency spike that appeared at regular intervals).
This appears to have been largely resolved in the machine's
favor. In my observation, it did find relevant frequencies, and
using the software eliminates the irrelevant spikes (except for
the first one in each scan, which is spurious). Jeff
Sutherland has used
the machine extensively in the past and found it reliable, though he now uses
The only issue I found with the DIRP is that
it can take so long as to be impractical. Therefore, I'm not
sure it justifies the machine's substantial extra cost, though
undoubtedly others who use it and are happy with it would
problem is that you can't just do a scan of the body from, say,
zero to 15 MHz (the machine's upper range), or even zero to 1
MHz, for a couple of
reasons. One is that you have to specify not only the range you
want to cover but the step size. The larger the step size, the
less time the scan takes but the less precision you get in each
step. Also, the unit is limited to 1,000 steps and takes about 1.5
seconds per step, so a scan of 100 steps takes 3 minutes; 1,000
steps takes 25 minutes.
DIRP screen in v. 1.6
for example, if you wanted to scan the entire range from zero to
15 MHz, you'd need a step size of 15,000 Hz — which
does you very little good. Even scanning zero to 1 MHz, the step
size would have to be 1,000 Hz. Quite a bit could be happening within
a single step that you wouldn't see. Considering the
precision you need to target a pathogen's frequency, even a step
size of 100 or 10 Hz may be too large, though these are often
used. But a step size of 10 Hz with 1,000 steps means you can
scan a range of only 10,000 Hz at a time.
25 minutes per scan, unless you already know or suspect where
the problems are, trying to do a large range in 10 kHz
increments could take quite a while — leaving no time for
therapy. And by the time you were done, the situation may have
changed, and you'd have to start over. Even then, you might miss
some in another range that you didn't scan.
final problem is that the
unit is limited to 50 hits, or resonant frequencies, per scan.
So if there are more than that (or you suspect there will be)
and you want to cover them all, you'd need to narrow the range
or increase the step size even further.
versions of the software are available: v. 1.6 and v. 2. Version 1.6, with its faults, is still better than v. 2,
which is even less intuitive (and doesn't have the Auto-R
output-limiting function). The software developer, the son of
the company's owner, said in an email in late 2010 that he
was planning a v. 3, but when it will be available is unclear.
This discussion relates to v. 1.6 unless otherwise indicated,
since that's the one I used almost exclusively.
I mentioned above, the software is amateurishly designed, with
a number of minor annoyances that add up — it requires a lot
of redundant mouse clicks and reopening of panes that close
automatically, and when you load a program, it displays a dialog
box that persists for 4 seconds (and seems like forever).
features operate erratically, particularly the Wobble (i.e.,
function when outputting a sequence of frequencies in Therapy
mode. I found that if the frequencies in a list change from square wave
(under 60 kHz) to sine, or vice versa, it causes problems —
the frequency and voltage
numbers turn red (indicating no output). According to an email
from the developer, this may be because the readout on the
software doesn't keep pace with what the machine is actually
doing, as displayed on the touchscreen.
Therapy screen in v. 1.6
solution was to set up the list in numerical order, which meant
there was only one place where the signal changed from square to
sine. Unfortunately, sometimes the output appeared to stop
anyway (according to the software, but not necessarily according
to the touchscreen). Therefore, until v. 3 comes along, it may
be preferable either to run the unit in standalone mode rather
than from a computer when using Wobble or to split the list in
two — one below 60 kHz, for square wave, and one above, for
only problem with setting up a list in numerical order is that
there's no easy way to reorder it or add frequencies between
existing ones. You can create a list in the Therapy screen by
entering one frequency at a time or by transferring a list of
hits from the DIRP screen. You can also import lists, such as
the Consolidated Annotated Frequency List (CAFL)
and a couple of others that come with the unit or any you create
(which must follow a specific format). But if you want to
reorder or add frequencies later, you have to redo it manually.
(If you want to redo an imported list, you can do it in Notepad
or even Word.)
Transfer (i.e., Therapy) screen in v. 2
can use Excel to edit lists created in the Therapy screen or
transferred from the DIRP screen, but it's cumbersome, because
the file contains a lot of other parameters for each frequency,
making it hard to use a simple sort function.
software provides no text field for notes or the name
of a program being run.
this sophisticated machine is hampered by its software, user
guides, and some limitations in the way certain features are set
up. But even if those improve, you may not find the scan
function worth the extra cost.
