Many years have been spent experimenting with various theories, ideas, and devices to develop this small , but powerful transmitter capable of transmitting Radio Frequency (RF) signals through the soil over a considerable distance.  The emitted signal is induced into the soil in an omni-directional pattern of 360°. It is because of this induced energy that makes the targets visible.  The Scanner emits the signal into the ground via the Power Transducer.  If the desired target is within range, the signal will be absorbed by the target.  The indicator Rods are plugged into the Power Module so as to complete the necessary tuned receiver circuit.  This circuit is formed through the combination of the operator's body capacitance and the inductive components of the Power Module.  This circuit will act passively until the operator actually walks through the transmission line between the Scanner and the Target.  This induced RF (Radio Frequency) energy from the transmission line interacts with the LC (Inductive-Capacitance) of the operator's circuit.  The normal response at that point is that the Rods will be attracted to each other.  This process actually conveys to the operator that the desired target is within range of the Scanner.  The range of the Scanner can vary for many reasons.  The first and most important variable is size of target.  That is followed by soil conditions (presence of electrolytes) and length of time in the ground.  Another factor which enhances the operational performance of the Scanner is the chemical change of the soil immediately surrounding the target.  Those targets which have a tendency to oxidize, whether it be the object itself or its container, will present a stronger signal.  Because of that oxidation factor, the target will offer a stronger potential for amplifying the Scanner's transmitted signal.

Standard Power Transducer-- This unit is responsible for delivering the selected signal of the Scanner to the ground plane of the strata via the two copper legs which are plugged into the ground.  The coax lead is the power supply line and attaches to the output of the Scanmaster. 

Power Module -- This unit's purpose is to power the Antenna Rods.  The unit contains a 9VDC battery for a power supply.  The battery condition is displayed when the Push Button on top is pressed in.  If the top indicator light is bright, the battery is okay.  If is is dim or out, the battery needs replaced.  To replace the 9 volt battery, simply open the module by rotating the bottom cap off.  The power module is turned on when the receiving Antenna Rods are plugged in the Power Module's receptacle.  When not in use, unplug the Rods from the Power Module! Storing the Power Module with the Rods plugged in will drain the 9 volt battery.  Do not allow the Rods to touch each other while attached to the module as this will short out the battery also!

Receiving Antenna Rods-- The rods are powered by the Power Module.  The purpose of the Rods is to indicate to the Operator that he or she has walked into the transmission line between the Power Transducer and the Target. The rods are normally held steady and balanced at waist level, and slightly in front of the Operator.  They are held pointed in a forward direction parallel to each other, and at a distance of 8 to 18 inches apart.  What each individual needs to discover is just what distance best relates to themselves.  This decision will be by trial and error.  Please remember that an individual who is relaxed and calm will operate the equipment more successfully than one who is tense and rigid  The rods will cross naturally by themselves when you enter the RF Energy line.  When it first happens for you, you will learned to anticipate success and will welcome it when it happens!

Dual Collectors -- These (2) devices are used as passive repeaters to aid in pinpointing the location of targets.  They are "passive: in that they require no power supplies and simply pick up the Scanner's initial signal and pass it on to the target.  Initially, the pair are used to triangulate in on the target.  Once the area surrounding the target is localized.
