Detailed instructions for use are in the User's Guide.
[. . . ] User controlled manual balancing of the ground has the additional benefit of giving the user the option of fine tweaking for different situations, thus increasing the probability of hearing the faint signals of small or deep targets. The Manual Ground Balance feature of the Pulsescan TDI Pro can be turned off if the ground mineralization is not severe enough to require it, as the pulse circuitry itself is able to ignore most ground mineralization by its very nature. In this situation, with the FINE GEB off, there is no audio tone variation all metal targets will sound alike, and additional depth can be attained in low mineralized grounds. White's is proud to have been able to work with Eric Foster, of Oxford, England, who enjoys the worldwide reputation of being the "Father of Pulse Technology".

TDI Pro Owner's Guide 5 1. [. . . ] If you were primarily looking for high conductive metals, such as silver, increase the Pulse Delay toward the maximum setting of 25 uSeconds, thus reducing the signals from very small trash items such as small iron and foil. Large iron usually falls into the category of silver, and gives a stronger signal at higher Pulse Delays as well. One important thing to remember is that whenever you change your Pulse Delay, you should check and readjust your ground balance as necessary.

GEB, Fine & Coarse (GROUND EXCLUSION BALANCE)What it does These two GEB controls FINE & COARSE adjust or balance the interference from ground mineralization. They are only operative when the FINE control is set clockwise from the OFF position. When FINE GEB is in the OFF position, the Pulsescan TDI Pro reverts to a straight pulse induction detector which hears all metal targets without Variable Audio, has no TARGET CONDUCTIVITY option, and no COARSE or FINE manual ground balance control. In any FINE ON (clockwise from off) position, the Manual Ground Balance and the Audio Tone features are functional. How to use it Ground Balance must be done with the Target Conductivity control set to All. To ground balance Pulsescan TDI Pro, the search coil is pumped slowly up and down from 1 inch near the ground to 6 inches above the ground while listening for a change in sound. Start this process with both the FINE and COARSE Controls at the center
TDI Pro Owner's Guide 21 of their range (12 O' clock). Begin pumping the search coil slowly up and down 1-6 inches from the ground. You will hear the high tone of low-conductive metal as you approach the ground. This eliminates the Ground Balance, Variable Audio Tone feature, and the selectable target conductivity feature. The Pulsescan TDI Pro circuitry handles the ground mineralization with its inherent Pulse Induction capabilities. All targets will sound alike, however, greater detection depth may be noted when searching low mineralized grounds. This activates the Ground Balance, Audio Tone, and selectable TARGET CONDUCTIVITY feature.

Mandatory settings if you cannot find the ground balance point, and wish to activate the variable Audio Feature. #1 - If you have set the Pulse Delay at 10 uS, which is recommended for average size gold, set the Ground Balance control at approximately 8. #2 - If you have set the Pulse Delay midway, set the Ground Balance at approximately 6. #3 - If you have set the Pulse Delay at 25 uS, which is suggested for beaches, relics, or very large targets, set the Ground Balance at approximately 2.
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.

2. Adjust Threshold Adjust THRESHOLD control 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.
