Conventional tools each fail in different conditions — no single technology reliably detects the full range of buried threats. SSOLAS uses different physics entirely, making it immune to the failure modes that limit every other method.

Non-metallic
casing
✓
Works reliably
SSOLAS detects changes in how soil transmits sound energy — unaffected by casing material. Non-metallic mines alter soil response the same way metallic ones do.
✗
Fails
Metal detectors are blind to plastic, wood, or ceramic casings — the most common modern landmine design.
~
Unreliable
GPR can detect density changes but produces high false-positive rates in complex soils and requires expert interpretation.
✗
Fails
Magnetometers require ferromagnetic material. Non-metallic mines produce no detectable magnetic signature.
~
Unreliable
May detect propellant chemicals but only in trace concentrations above ground. Depth and soil type limit reliability.
High soil
conductivity
✓
Works reliably
Seismic wave propagation is independent of electromagnetic conductivity. SSOLAS performance is stable in high-conductivity soils.
~
Unreliable
Wet or conductive soils reduce metal detector sensitivity and increase false alarms significantly.
✗
Fails
GPR signals attenuate rapidly in high-conductivity soils (clay, saline). Effective depth can drop to centimeters.
✗
Fails
High soil conductivity creates electromagnetic noise that overwhelms magnetometer signals.
~
Unreliable
Largely unaffected by conductivity, though moisture can suppress vapor transport to the surface.
Electro-
magnetic
interference
✓
Works reliably
SSOLAS uses mechanical (acoustic/seismic) energy, not electromagnetic signals. EMI has no effect on sensor performance.
~
Unreliable
Susceptible to EMI from power lines, vehicles, and military electronics. Requires specialist operators in high-EMI environments.
✗
Fails
GPR systems are highly sensitive to EMI, which can completely mask target returns in active conflict zones.
✗
Fails
Magnetometers are extremely sensitive to EMI — virtually unusable near active military hardware or power infrastructure.
✓
Works reliably
Chemical vapor sensing does not rely on electromagnetic signals and is unaffected by EMI.
Variable
soil types
✓
Works reliably
Field testing conducted specifically across soil types where conventional detection is unreliable. Consistent, measurable signal differences observed across all tested conditions.
~
Unreliable
Performance varies by soil mineralogy. Iron-rich soils generate false positives. Each new site may require operator recalibration.
~
Unreliable
Must be recalibrated for each soil type. Rocky or heterogeneous soils produce high clutter and ambiguous returns.
~
Unreliable
Background magnetic mineral content varies by geology. Laterite and basalt soils are particularly challenging.
~
Unreliable
Soil chemistry affects vapor transport. Highly adsorptive soils trap chemicals before they reach the surface.
