A really

to monitor
strata
displacement.
How does it work?
FIRST TRIGGER: The RockSpy is anchored in the competent strata layer. Once separation starts to occur, the roof or hanging wall will push the flange downwards. This will trigger a blue reflective piston and it will snap out.
SECOND TRIGGER: The roof or hanging wall might move again. The flange will be pushed further to trigger a red reflective piston. This piston will snap out over the blue reflective piston. The blue reflective piston is no longer visible.

How to install
With the anchor point first, push the RockSpy upwards into the drilled hole. Once the locking-pin reaches the roof or hanging wall, remove the pin and push further until the **flange stops firmly against the roof or hanging wall. Ensure no gap is between the **flange and roof or hanging wall surface.

The RockSpy can be supplied in any given quantity. Slight price adjustments are made on devices longer than 2m.
The RockSpy was designed specifically to be installed in lower underground mining areas.
Apart from the **Flange, no other part protrudes from the drilled hole and makes the RockSpy less prone to vehicle and blasting damage.
