FEATURES
The Marksman II Ultrasonic Diagnostic Tool converts and amplifies
inaudible ultrasonic sound into audible “natural” sound by
employing technologically advanced circuitry. It operates on the
principle of detecting high frequency ultrasonic waves, which are
created by friction from all moving parts, whether solid, liquid or
gaseous. These “sounds” reside far above the range of the human
ear and tend to be highly directional.
This directional aspect of ultrasonic waves allows one to isolate a
suspect signature sound from other background noises and detect its
exact location. This sound analysis can be used for efficiently
investigating the following areas of repair and preventive mainte-
nance in the following transportation and industrial applications:
1. Air leaks

packet or wave front which can result in an ultrasonic
emission with a differential of 5 psi from a 12 inch (30.5 cm)
distance, and/or a hole down to 0.004 inches (0.1 mm) in
diameter.
2. A/C refrigerant leaks (for most types of refrigerant)
3. Gas and liquid turbulence
Turbulence associated with steam trap and internal valve
leaks, cavitation, and blockages in liquid and air/gas lines.
4. Electrical discharge
Electrical discharge associated with insulation breakdown,
tracking, corona and arcing.
5. Diagnosing solenoid operations
6. Mechanical wear
State of mechanical wear in bearing and race assemblies,
shafts and gears (also indicating the state of lubrication).

relatively small that the sounds they produce are above the range
of human hearing. Most commonly, these faults generate sounds
in the 38,000 to 43,000 cycles per second range, generally
referred to as being in the ultrasonic range.
To employ the ultrasound methodology in a usable manner, it is
imperative that the listener have access to an audible sound that
bears a resemblance to the natural sound of the defect.
A mechanical bearing with a defective ball should sound like such.
Likewise, converting the ultrasound frequencies to audible
frequencies is not sufficient with regard to rendering a usable
signal. For this reason, the Marksman II incorporates a
process whereby the audible signal bears a close likeness to
the natural incoming sample. We call this process “Sound
Signature Technology,” whereby a gas leak sounds like a gas leak
and a defective bearing sounds like one.
GENERAL INFORMATION
The Marksman II is sensitive only to ultrasound (40.5 kHz) and is
unaffected by audible noise. Internal Noise Control (I.N.C.) allows
the use of this instrument in extremely noisy environments such as
mechanical rooms, around operational chillers, etc. Drag your
finger upwards on the sensitivity touch pad to increase sensitivity
when experiencing little or no environmental noise. Drag your
finger downwards on the sensitivity touch pad to reduce sensitivity
in response to an increase in environmental noise. The I.N.C.
works much like a two-way radio squelch allowing only the
strongest and closest signals to penetrate the electronic wall built
by the I.N.C. circuitry.
Many variables can affect the amount of ultrasound generated by
the leakage of gas through an orifice. Such factors include the
pressure/vacuum versus the surrounding environment, how
smooth the edges of the orifice are, the diameter of the orifice, the
leak detector’s distance from the orifice and the presence of air-
flow, which may dissipate the ultrasound. As you use the
Marksman II, keep in mind that these factors may affect your abil-
ity to detect ultrasonic leaks.
