PulseScan TDI Owner’s Guide 7
ENGINEERING DESCRIPTION -
Although the new Pulsescan TDI was designed with the Gold Prospec-
tor 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 pos-
sible, and easy to operate in addition to producing outstanding performance at an
affordable price.
The Pulsescan TDI is a deep searching, very sensitive pulse induc-
tion metal detector which incorporates a true user controlled manual ground
balancing feature, a byproduct of which is the ability to produce an audio tone,
for possible identification of the detected target. User controlled manual balanc-
ing 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 can be turned off if the ground mineralization is not severe
enough to require it, as then the pulse circuitry itself is able to ignore most
ground mineralization by its very nature. In this situation, with the Ground
Balance toggle off, there is no audio tone variation - all metal targets will sound
alike, and additional depth can be attained.
White’s is proud to have been able to work with Eric Foster, of Oxford,
England, who enjoys the world wide reputation of being the “Father of Pulse
Technology”.
