PulseScan TDI Owner’s Guide ASSEMBLY INSTRUCTIONS 1. Remove all parts from the shipping carton and check assembly page to make sure all parts are present. 2. Install black rubber washers on fiber clevis/lower rod, insert clevis lower rod onto loop ears. Use only nonmetallic washers, fiber bolt, and fiber thumbnut to secure loop/search coil to clevis/lower fiber rod. 3.
PulseScan TDI Owner’s Guide 8. Adjust the elbow cup strap so that it is loose enough for you to slide your arm in and out without loosening each time you want to set the detector down. The elbow cup strap provides extra leverage and control. However, some prefer not to use it. 9. Install battery as described in next section. 10. It should be noted at this point that the detector may not work as expected indoors due to the high degree of metal used in modern construction.
PulseScan TDI Owner’s Guide ENGINEERING DESCRIPTION Although the new Pulsescan TDI was designed with the Gold Prospector in mind, its features and performance will be just as valuable to Beach & Relic Hunters. During the development of the PulsescanTDI, we kept in mind the comfort of the user by designing an instrument which would be as light as possible, and easy to operate in addition to producing outstanding performance at an affordable price.
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. It supplies a nominal voltage of 14.4 volts and approximately 500ma of current to the detector during operation.
PulseScan TDI Owner’s Guide To recharge the battery: 1) 2) 3) 4) 5) 6) 7) 8) 9) 10) 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. The RED light then comes on to indicate the battery is charging.
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. How to use it The locking mechanism prevents this toggle from accidentaly being bumped. This is particularly valuable while operating the various control knobs. Just lift the spring loaded toggle to release the lock and move the toggle.
PulseScan TDI Owner’s Guide 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. How to use it In most detectors, including the Pulsescan TDI, the threshold is adjusted to a faintly audible level by turning the knob clockwise.
PulseScan TDI Owner’s Guide THRESHOLD LEVELS ... NOT RECOMMENDED Threshold Level Noise ➟ ➟ Chatter can be heard in Threshold IDEAL Threshold Level Noise ➟ ➟ Threshold set above chatter so chatter is not heard.
PulseScan TDI Owner’s Guide 13 TARGET CONDUCTIVITY - What it does This control allows the user to select whether he wishes to hear only lowconductive targets, only high-conductive targets, or both low and high conductive targets. Low-conductive targets, like small-to-medium sized gold nuggets will make a high-tone sound. High-conductive targets like coins, except nickels, will make a low-tone sound. This feature only works if the Gnd Bal toggle is in the on position.
4 PulseScan TDI Owner’s Guide ALL ➟ Both High and Low Conductivity Targets RESPOND HIGH ➟ Only High Conductivity Targets RESPOND LOW ➟ Only Low Conductivity Targets RESPOND
PulseScan TDI Owner’s Guide 5 when laying flat in the ground and large pieces of iron, large pieces of lead, lead mini balls, lead musket balls, lead loom weights, bronze buckles, bronze weights, bronze artifacts, etc. NOTE: Mineralization, coil size, and ground balance settings can also reverse the readings. Some low-conductive metals could make a low tone, and/or some high-conductive metals could make a high tone. Set to ALL for both high and low-conductive metals.
PulseScan TDI Owner’s Guide FREQUENCY - What it does This control makes small adjustments up or down to the transmitter pulse frequency or rate. This is used to counteract any interference which might be due to outside electromagnetic sources, such as radio stations, microwave, short wave, electric fences, power lines, lightening, electrical storms, or other metal detectors being used nearby.
PulseScan TDI Owner’s Guide 17 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. How to use it PULSE DELAY is measured in micro seconds (uS). 10 uS is the lowest setting, which samples as close as possible to end of the transmitter pulse.
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. You may hear nails when swept across the broadside, but not when sweeping from tip to tip.
PulseScan TDI Owner’s Guide 19 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. How to use it Ground mineralization gets in the way of hearing target signals.
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. The threshold will let you know if the gain is set too high.
PulseScan TDI Owner’s Guide 21 GROUND BALANCE ON/OFF - TOGGLE What it does The Toggle Switch, located below the Ground Balance knob, is used to either enable or disable the ground balancing function (along with the Variable Audio Tone feature). In the ON position, the Manual Ground Balance and the Audio Tone feature are functional.
PulseScan TDI Owner’s Guide Option # 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. Option # Switch the toggle to On. This activates the Ground Balance, and Audio Tone feature.
PulseScan TDI Owner’s Guide 23 GROUND BALANCE - KNOB What it does This control adjusts or balances the interference from ground mineralization. It is only operative when the 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. This process must be done with the Target Conductivity control set to All.
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. If you change the setting on the Gain or the Pulse Delay, you should adjust the Ground Balance setting if needed.
PulseScan TDI Owner’s Guide 5 INITIAL SET-UP - To get started, set the controls to a mid-range position. For now, the main concern is setting the threshold, and adjusting the settings for the other controls. # - Set the controls to mid-range as follows Ground Balance 6 (will only be active when Gnd.Bal. Conductivity All toggle is ON) Freq.Adj. 12 noon (If there is interference select a quiet frequency) Pulse Delay 10 uS Gain 6 Gnd.Bal.
PulseScan TDI Owner’s Guide #2 - TURN ON AND ADJUST THRESHOLD Turn the power switch On and adjust the threshold to a faint hum, as noted under “Description of Controls”. The threshold hum should be set just above the chatter point so that the hum is reasonably continuous - faint, but steady. #3 - GET FAMILIAR WITH A TARGET SOUND Put a target on the ground to become familiar with the response of the detector. Use a nickel or a gold nugget.
PulseScan TDI Owner’s Guide 27 #4 - DETERMINE IF GROUND BALANCE IS NECESSARY (With Gnd. Bal. Toggle OFF as on Chart A.) At this point it is important to find out if there is enough mineralization in the ground to require the Ground Balance control to be activated. Since in the initial setting recommended above, the Gnd.Bal. toggle is set to off there is no active ground balance, and the Pulsescan TDI has only its inherent ground rejection ability working for it.
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. Either low, high or both low and high. Dependability varies with the size, shape, conductivity, and metal content of the target as well as the type of ground mineralization. In prospecting even the form of the gold (placer, sponge, crystalline etc.
PulseScan TDI Owner’s Guide 29 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. It might be noted that the low tone heard over large non-iron targets is usually smoother than the low tone heard over iron targets which can be irregular.
PulseScan TDI Owner’s Guide MORE ON PULSE DELAY Sampling as close as possible to the end of the transmitted pulse gives the highest sensitivity to all metal targets regardless of their content or conductivity. The best signal from all targets is obtained when using a short (10 uS) delay.
PulseScan TDI Owner’s Guide 31 Delay affects the signal, you can try the same tests with the Ground Balance on and the Conductivity Toggle to all. At this time you can observe whether the target produces a high tone or a low tone. You can then choose either the low or high settings to observe how the Conductivity Toggle setting can eliminate or accept a target.
