Why this instrument
The Mini 360° Prism with L-Bar is built for surveyors who need a compact target that remains accurate in demanding site conditions. Its small size provides excellent centring accuracy while the 360° prism allows uninterrupted robotic tracking from any direction, making it well suited to single-operator workflows.
The integrated L-bar bracket makes installation straightforward for permanent monitoring applications on bridges, tunnels, rail corridors, mining infrastructure and construction projects.
This model is particularly suited to robotic total station surveys for construction and mining projects across Australia where durable, permanently mounted targets are required.
What sets it apart
- Full 360° robotic tracking: Allows robotic total stations to maintain lock from virtually any direction, reducing interruptions during surveying and setout work.
- Compact prism design: The smaller prism body delivers a centring accuracy of ±1.5 mm, helping improve overall survey precision where accurate positioning matters.
- Permanent L-bar mounting: The robust L-bar bracket provides a stable mounting solution for long-term monitoring installations on infrastructure and construction projects.
- Long robotic tracking range: Supports ATR up to 350 m typical, approximately 400 m under ideal conditions.
- Compatible with Leica and Trimble systems: Supports Leica (+28.4 mm prism constant) and Trimble (−6.0 mm prism constant) for easy integration into existing workflows.
- Standard 1/4" mounting thread: Installs onto common survey brackets and monitoring fixtures without specialised hardware.
- Optimised for robotic workflows: Ideal for feature surveys, construction setout, machine control support, monitoring applications and robotic total station operation.
- Lens options for maximum performance: Copper-coated lenses preferred for Leica; silver-coated for Trimble. Contact Terra360 before ordering if unsure.
