  • Page 7: Engineering Description

    The Manual Ground Balance feature of the Pulsescan TDI can be turned off if the ground mineralization is not severe enough to require it, as then the pulse circuitry itself is able to ignore most ground mineralization by its very nature.
  • Page 8 8 PulseScan TDI Owner’s Guide CHARGING SYSTEMS, BATTERIES AND BATTERY CONDITION - Batteries and Charger The PulsescanTDI uses a rechargeable Lithium Ion battery pack as the power source. This type of battery can supply the high current levels required by the detector and weights much less than other battery packs that have the same power characteristics.
  • Page 9 PulseScan TDI Owner’s Guide 9 To recharge the battery: Connect the battery pack to the charger and plug the charger into the A.C. outlet. ) The light in the charger will flash RED-GREEN-RED- GREEN. This is a self check that indicates the charger is operating correctly.

    0 PulseScan TDI Owner’s Guide CONTROLS POWER - What it does This traditional control turns on or off the POWER from the internal, chargeable, Lithium Ion battery pack. The toggle switch incorporates a locking device to prevent accidental movement off or on.

  • Page 11: Threshold

    What it does This control adjusts the threshold of the unit. This is the faint background hum which is present during the normal operation of the Pulsescan TDI. This hum, which is always present, is increased when the knob is turned clockwise.

  • Page 13: Target Conductivity

    PulseScan TDI Owner’s Guide  TARGET CONDUCTIVITY - What it does This control allows the user to select whether he wishes to hear only low- conductive targets, only high-conductive targets, or both low and high conduc- tive targets. Low-conductive targets, like small-to-medium sized gold nuggets will make a high-tone sound.

  • Page 16 This interference is recognized by a warbling or pulsing of the audio threshold in a repetitive way, and can mask target signals. The Pulsescan TDI has a frequency range of 3.25 kHz to 3.37 kHz pulses per second.

  • Page 17: Pulse Delay

    PULSE DELAY - What it is The Pulsescan TDI transmits a pulse and then after a time delay, samples the received signal. This is the control knob for adjusting the sample pulse delay. It alters the time between the end of each transmitter pulse, and the start of the receiver sampling period.
  • Page 18 8 PulseScan TDI Owner’s Guide medium gold nuggets, small or thin gold rings, and chains as well as very thin, small hammered silver coins. If you were detecting for thin gold rings at a beach, this would also be the proper setting to achieve the most sensitivity. Of course, at 10 uS you will also hear small bits of iron trash, bits of foil, boot tacks and bits of nails, and very small pieces of lead like bird shot.

  • Page 19: Gain

    PulseScan TDI Owner’s Guide 9 GAIN - What it does Gain controls the sensitivity of the detector, and the range at which the detector will hear a given target. It increases or decreases the amplification of the receive signal. In other words, it determines how deep the detector will hear a target.
  • Page 20 0 PulseScan TDI Owner’s Guide You must operate with a threshold which is as smooth as possible, so you can hear the clarity of a true signal, and not be confused by false signals, chatter, or blanking out of the threshold hum. Keeping the detector ground balanced is important, but one of the best ways to keep a smooth operation is to apply the appropriate amount of gain.
  • Page 21 This means the Pulsescan TDI circuitry can handle the ground without manual ground balancing, and the Gnd Bal toggle could be...
  • Page 22 You may switch the toggle to Off. This eliminates the Ground Balance control, the Audio Tone feature, and the selectable conductivity feature allowing the Pulsescan TDI circuitry to handle the ground mineralization. All targets will sound alike, but you will get better depth.
  • Page 23 Ground Balance toggle switch is in the On position. How to use it To ground balance Pulsescan TDI, the search coil is pumped slowly up and down from one inch near the ground to 6 or 8 inches above the ground while listening for a change in sound.
  • Page 24 4 PulseScan TDI Owner’s Guide where you hear only the faint hum of the threshold is where the Pulsescan TDI is balanced to the ground. You will have to turn the knob very slowly in very small increments to reach the most exacting point for eliminating ground minerals. At this point, you will most likely notice that the Ground Balance knob is usually between 8 and 9 on the scale.

    PulseScan TDI Owner’s Guide 5 INITIAL SET-UP - To get started, set the controls to a mid-range position. For now, the main con- cern is setting the threshold, and adjusting the settings for the other controls. # - Set the controls to mid-range as follows - Ground Balance (will only be active when Gnd.Bal.
  • Page 26 Put a target on the ground to become familiar with the response of the detector. Use a nickel or a gold nugget. Please note that the Pulsescan TDI is a motion detector which means that as the search coil passes over the target you hear a response only when the search coil is kept in motion.
  • Page 27 At this point you have two options as already described on Page 22. a) You may leave the Gnd Bal toggle in the Off position and operate the Pulsescan TDI with no Variable Audio as a straight pulse detector, and dig all targets, or ...
  • Page 28 8 PulseScan TDI Owner’s Guide MORE ON VARIABLE AUDIO (low/high tone) Only if the Gnd Bal toggle is set in the on position will this Variable Audio feature be active. You may then select the type of conductivity feature you wish to use.
  • Page 29 PulseScan TDI Owner’s Guide 9 Therefore, on a low-conductive target (small to medium gold, nickel coins, and small iron) the pitch of the audio tone might rise. When the search coil goes over a high-conductive target (large gold, most silver and copper coins and most large iron) the pitch of the audio tone might fall.

    In this way, you can observe what happens to certain targets as the Pulse Delay is advanced up from 10 uS. Setting pulse delays can be an impor- tant part of operating the Pulsescan TDI. After you have seen how the Pulse...
  • Page 31 This was found out during our initial testing of the Pulsescan TDI on an extremely black sand salt water beach. The Pulse Delay was initially set at 10 uS. At once, we found that we had trouble achieving a clear ground balance point as the extreme negative black sand and salt were too reactive.
