Why This Instrument
The MPC102 Cats Eye Prism is built for monitoring work where surveyors need a low-profile, durable and repeatable target installed in a fixed or semi-permanent position. Its +20° angled housing improves line-of-sight acquisition, helping the total station pick up the target more efficiently from practical field positions.This model is particularly suited to deformation and movement monitoring where repeated measurements need to reference the same point over time. For Australian road, bridge, rail and mining projects, the MPC102 gives crews a compact monitoring target that can stay in place and support consistent measurement across multiple survey visits.
What Sets It Apart
- 17 mm prism diameter: Provides a compact reflector for monitoring points where a full-size prism would be too large or exposed.
- +20° angled housing: Improves line-of-sight acquisition by presenting the reflector at a practical angle for total station observations.
- CNC aluminium housing: Gives the prism a robust body suitable for road, rail, bridge, mining and civil monitoring environments.
- Weather-resistant design: Helps protect the prism during long-term outdoor monitoring on exposed infrastructure sites.
- Up to 300 m measuring range: Supports practical monitoring observations across road pavements, bridges, rail corridors and mine sites.
- Permanent or semi-permanent installation: Allows surveyors to establish repeatable monitoring points that remain in position between measurement cycles.
- Suitable for deformation monitoring: Helps crews track movement in bridges, settlement zones, rail tracks, pavements and mining ground conditions.
- Low-profile monitoring target: Reduces obstruction risk compared with larger prism assemblies, making it practical for installed monitoring locations.

Works With
The MPC102 Cats Eye Prism works with monitoring and total station workflows used across Australian civil, infrastructure, rail and mining projects, including:
- Road pavement monitoring programs
- Bridge deformation monitoring setups
- Mining ground movement monitoring
- Settlement monitoring points
- Rail track movement monitoring
- Repeat total station observation workflows
- Permanent and semi-permanent monitoring installations
This prism is best used where surveyors need to return to the same monitoring point over time and capture repeatable measurements from a known target location.
