White’s Pulsescan Field Manual
Yes, the Pulse Scan TDI makes a wonderful Turf Detector: The aforementioned beach tips like wise apply when
running the TDI at 10uS on the pulse delay. Unfortunately, the parks have a high concentration of trash items, par-
ticularly shards of aluminum and foil that sound off strong at 10uS, even with the TDI’s Gain set low.
• Ground Balance at 2 to 3 (8 to 9 O’Clock)
• Pulse Delay at 25 uS
• Gain low from Minimum to 12 O’Clock High
POWER TIP -
At 25uS pulse rate, and a lowered Gain at minimum or slightly elevated, the Pulse Scan TDI will ignore most small
low-conductive foils and aluminum shards that would normally give a stronger high tone response at 10uS. This is
not to say that you couldn’t run the TDI at 17.5 uS. Nickels and gold rings will still be detected deeply. The ability
to ignore most of the common trash that will be a nuisance to a VLF Detector which has to rely more on Tone ID and
Visual ID which becomes less accurate beyond 4”, gives the TDI a big advantage over standard metal detectors.
POWER TIP -
• Pulse Rate at 10 uS
• Ground Balance at 2 to 3 (8 to 9 O’Clock)
• Gain set as high as possible for maximum Signal Response
• Conductive Switch to High Conductors Only.
Comment:
Using this tip, the Pulse Scan TDI will ignore all the nuisance low-conductive target such as foils, aluminum tabs,
steel bottle caps and because of the Pulse Rate and Ground Balance position, the normally high-conductive rusty
nails turn and become low conductors like aluminum and foil and are subsequently ignored. The TDI will hear those
deep Silver Coins, Quarters etc without having to listen to 90% of the other responses which are usually low conduc-
tive.
