This is an actual Geophone sensor that scientists use to
detect earth quakes, that's how sensitive it is.
Don't be fooled by others saying their product is a
Geophone, most are using sensors that are nowhere near as sensitive as the
Geophone sensor but advertise otherwise. We are the originators of a geophone
sensor for the Paranormal community.
Work's off 4 AA Batteries.
Extremely sensitive detection of movement, footsteps,
banging on walls, walking, etc.
Full adjustment knob for filtering out ambient vibration's.
Super bright multi-colored LED's that indicate the 10 stages
of shock, 3 green for the slight vibration, 3 amber for medium vibration, and 4
red for high vibration. Designed for filming in night vision.
