Locating Steel Drums
As shown in Figure 18, the signal pattern will vary depending on the vertical or horizontal
orientation of the drum and how deep it is buried. A 55 gallon drum can be located at depths
of up to 10 feet.

Additional Notes
1. SPOT can detect buried ordnance and discarded weapons. SPOT is a viable tool for use
by the military and local/state police departments.
2. People drilling in an area where hazardous materials might be encountered can use
SPOT to search the area prior to drilling.
3. A burbling sound indicates the presence of an energized power line or the presence of
50/60Hz.
4. The instrument will not respond to non-ferrous metals such as gold, silver, copper,
brass and aluminum.
