A detector system for detecting underground anomalies comprising:
- a detector device, comprising:
- a housing;
- a fluid chamber within said housing, the fluid chamber containing a fluid, wherein said fluid chamber is sealed;
- a float positioned within the fluid chamber, said float comprising a sealed chamber having an upper end and a lower end with a target attached at the lower end, wherein said float is configured for free floating movement in said fluid;
- a proximity sensor within said housing, said proximity sensor positioned beneath said target and configured to detect a distance of said target from said proximity sensor,
- wherein a presence of an underground anomaly is determined based on said detected distance.
