[. . . ] 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".

[. . . ] 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. Aluminum & pull-tabs will also be heard. Very low pulse delays can also result in the detection of conductive salt water when detecting along beaches. Typically 17. 5 uS is the best Pulse Delay when searching wet salt. 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. 20 TDI Pro Owner's Guide MORE about Target Conductivity is listed under VARIABLE AUDIO on page 27 of this guide. GEB, Fine & Coarse (GROUND EXCLUSION BALANCE)What it does These two GEB controls FINE & COARSE adjust or balance the interference from ground mineralization. FINE makes minor adjustments, COARSE major adjustments. They are only operative when the FINE control is set clockwise from the OFF position. 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. Ground Balancing is more difficult at higher GAIN settings. 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. If you are not able to find a ground balance point (Threshold remains steady, COARSE makes no difference) there are two options ­ Option #1 You may search with the GEB FINE control OFF (fully counter clockwise).

The foregoing is the only warranty provided by White's as the manufacturer of your metal detector. Any "extended warranty" period beyond two years, which may be provided by a Dealer or other third party on your detector, may be without White's authority, involvement and consent, and might not be honored by White's Electronics, Inc. 34 TDI Pro Owner's Guide WHITE'S USA WARRANTY TRANSFER If for any reason you should sell your Pulsescan TDI Pro prior to the date the warranty expires, the remaining warranty is transferable. This transfer is authorized by calling 1-800-547-6911, and getting an Authorization Number. [. . . ]
