White’s Pulsescan TDI Field Manual
Beach Hunting Settings -
• Ground Balance ON
• Conductivity Toggle set to ALL
• Frequency Adjust set to 12 O’clock Noon
• Set the Gain initially at minimum
• Set the Threshold to a Steady Smooth Tone (like a mosquito buzzing in your ear)
• Set the Pulse Delay at 10 uS (Best Sensitivity to All Metals)
• Set the Ground Balance Control 6 or High Noon
• Now, raise the Gain up as high as possible as long as TDI operates stable. Reset the Frequency Adjust
as needed or reduce the gain. It should be noted that even with the Gain down all the way, you’ll still hear
very deep coin targets, but their response would be attenuated due to the lower gain. The benefit of lower
gain is increased smoothness, stability and in some cases with coin size or increased smoothness, stabiity
and in some cases with coin size or larger targets, one can better estimate the depth of the target.
Comment:
After hunting a number of salt-water beaches I ran into the following target scenarios.
HIGH Conductive Coins (Quarter, Dime, Penny) -
Initial Target Response: Low Audio Tone…. cross sweep the target looking for a coin-size and shape response.
If your hearing more than a single continuous response over the target, lift the loop up a couple of inches and repeat
the process or with your free hand, reach over and turn the large Ground Balance control CCW (to the left) and re-
scan the target. Coins should STILL respond with a LOW Tone. If the Audio Response turns to a HIGH Tone, the
target is most likely contains Ferrous (Iron) content.
LOW Conductive Coins, Rings, (Nickels, White or Yellow Gold Rings) -
Initial Target Response: HIGH Audio Tone… Cross Sweep the Target looking for a COIN-SIZE & SHAPE Response.
If your hearing more than a single continuous response over the target, lift the loop up for a couple of inches and
repeat the process OR with your free hand, reach over and the large Ground Balance control CW (to the right) and re-
scan the target. Coins and Rings should STILL respond with a HIGH Tone. IF the Audio Response turns to a LOW
Tone, the target most likely contains Ferrous (Iron) content.
POWER TIP -
In either of the techniques regarding HIGH or LOW Conductive Targets, note how the amplitude (strength) of the
signal diminishes… this could also indicate a particular type of target. This is particularly true with a Quarter versus a
Zinc Penny. The Quarter exhibits a stronger signal than the Zinc Penny. The Nickel or Ring remains stronger than a
small shard of aluminum.
POWER TIP -
Very Strong Targets can sound off with strong COMBINATIONS of LOW and HIGH Tones and should be
investigated….. you’ll find Keys, Fishing Lures, Lead Sinkers and unique shaped metal targets like a vintage WW1
Hand Size Lead Toy Soldier.
