[. . . ] TDI Pro Owner's Guide 1 OWNER'S GUIDE TDI Pro TM White's Electronics, Inc. Manufacturers of the World's Finest Metal Detectors 2 TDI Pro Owner's Guide Although the new Pulsescan TDI Pro was designed with the Gold Prospector in mind, its features and performance will be just as valuable to Beach, Relic, and serious coin Hunters. During the development of the Pulsescan TDI Pro, we kept in mind the comfort of the user, easy to operate, in addition to producing outstanding performance at an affordable price. The Pulsescan TDI Pro is a deep searching, sensitive pulse induction metal detector which incorporates a user controlled manual ground balancing feature, a by product of which is the ability to produce an audio tone, for possible identification of the detected target. [. . . ] 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. Again, FINE is used to make minor adjustments. COARSE is used to make major adjustments. 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. Start turning the COARSE knob slowly clockwise as you continue this pumping process. The high tone will usually continue with each pump toward the ground for a short period of time, and then start to fade to no tone other than the threshold hum. Continue the process of pumping slowly, turning the knob clockwise past the quiet zone. You will begin to hear the low tone as you approach the ground. If the ground has moderate mineralization you may not hear the low tone. At this point, continue with the pumping process (1-6 inches from the ground), and start turning the COARSE knob back counter clockwise until you near the quiet zone again. NOW switch to the FINE control and fine tune for as little change in Threshold as possible while pumping the search coil 1-6 inches over the ground. This area of quiet, where you hear only the faint hum of the threshold, is where the Pulsescan TDI Pro is balanced to ignore the ground. You will have to turn the knobs very slowly in very small increments to reach the most exacting point for eliminating ground minerals. Once close, switching to the FINE control eases this process most obviously in extreme ground mineralization. At this point, you will most typically notice that the COARSE knob is between 8 and 9 on the scale. What is important is being able to pump the search coil 1-6 inches over the ground with no change in Threshold, indicating the Pulsescan TDI Pro doesn't see the ground. If you change the Gain or Pulse Delay, you should re-check and re-adjust the Ground Balance setting as needed.
