The Rothbucher RSL420M is a precision laser scanner target with ball-bearing swivel and tilt function, designed for 3D laser scanning, photogrammetry, and drone surveying workflows requiring accurate, repeatable fixed reference points. Its ball-bearing joints allow the target face to be aligned smoothly in any direction - including difficult angles on walls, ceilings, and structural surfaces - while remaining precisely on axis and in position throughout the scan. The RSL420M is printed on one side with offset 0, making it the standard choice for general-purpose scanner reference applications where a single viewing direction is sufficient.

The RSL420M is built around an 11-magnet special magnetic base that provides fast, tool-free attachment to any metallic surface without adhesives, drilling, or surface preparation. The 100mm tilting axis height matches common survey prisms, allowing XYZ coordinates to be determined precisely with a total station when needed - connecting scanner data to a surveyed coordinate system with sub-millimeter accuracy. Optional suction cup mounts extend the RSL420M to smooth non-metallic surfaces such as glass and furniture fronts. RSFP-X90 adapter compatibility allows placement on any standard tripod or tribrach, or directly over an RS Mini Prism for combined scanner and total station workflows. Sold in a box of 2.

Key Features

• Ball-bearing swivel and tilt joints - allows smooth, precise target alignment in any direction while maintaining exact on-axis position; no drift or slippage during scanning
• 11-magnet special magnetic base - provides secure, tool-free attachment to any metallic surface for fast deployment without adhesives or drilling
• Printed one side, offset 0 - zero-offset configuration for exact reference point measurement from a single viewing direction
• 100mm tilting axis height matches common survey prisms - XYZ coordinates can be determined with a total station for precise georeferencing and coordinate system connection
• Compatible with RSFP-X90 adapters (sold separately) - mounts on any standard tripod or tribrach, or positions the target directly over an RS Mini Prism
• Dual use as scanner target or drone target - single target type supports both terrestrial scanning and aerial photogrammetry workflows
• Suitable for indoor and outdoor use - robust magnetic base and UV-stable target face perform reliably across construction, industrial, and field environments
• Fixed reference point capability - links multiple scan positions and assigns spatial reference information to geodata sets for complete point cloud registration
• Part of Rothbucher's "One reference point for all instruments" accessory system - compatible with the full range of RS sockets, adapters, suction cups, and mini prisms
• Sold in a box of 2

Compatible Instruments

• Leica laser scanners - BLK360, RTC360, P-Series
• Faro laser scanners - Focus series
• Zoller+Fröhlich (ZF) laser scanners
• Trimble laser scanners - X7, X9
• Geomax laser scanners
• Drone / UAV photogrammetry systems (as ground control target)
• Total stations (via RSFP-X90 adapter and RS Mini Prism, for tachymetric coordinate determination)

Common Applications

• 3D laser scan point cloud registration - fixed reference points for connecting multiple scan positions with sub-millimeter accuracy
• Construction as-built documentation and BIM data capture
• Industrial plant and facility scanning - magnetic base attaches directly to structural steel without surface preparation
• Drone photogrammetry ground control - dual-use target functions as GCP for UAV survey missions
• Georeferencing and geodata set linking - assigns spatial coordinates to scan data for integration with surveyed control networks
• Mixed scanner and total station workflows - 100mm axis height and RSFP-X90 compatibility allows the same reference point to be used with both instruments
• Indoor scanning on non-magnetic surfaces - suction cup mounts extend deployment to glass, tile, and finished wall surfaces
