[. . . ] 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. [. . . ] 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. 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. Often only FINE control adjustments are necessary after the initial COARSE setting. In addition, if you begin to hear ground noises (false signals) you should also re-adjust the 22 TDI Pro Owner's Guide Ground Balance. If it appears impossible, reduce GAIN and try again. If the Pulsescan TDI Pro does not require ground balancing, there is another option. When pumping the search coil 1-6 inches over the ground and turning the COARSE GEB control, if the COARSE position makes no difference, there isn't any change in the Threshold regardless of the COARSE control position, the Pulsescan TDI Pro can be operated as a standard pulse detector with no variable audio, by turning the FINE control fully counter clockwise to off. The upside the detector may detect deeper in such low mineral grounds. If the Pulsescan TDI Pro does achieve ground balance (COARSE control position DOES influence Threshold as the search coil is pumped 1-6 inches over the ground), the FINE control must be used Clockwise of OFF. The Ground Balance, Variable Audio, and TARGET CONDUCTIVITY feature will be active. This situation indicates that there is enough iron mineralization to balance. Again, the FINE control must be in the ON position (clockwise from OFF) when the COARSE GEB makes a difference in Threshold as the search coil is pumped 1-6 inches over the ground, and you must select a target conductivity option.
