Compact mini prism designed for Swiss style total station surveying with a 17.5mm prism offset. Purposebuilt as a precise reflector target for staking, control point measurement, and routine field surveys. Key benefits Accurate offset matching: The fixed 17.5mm offset ensures correct horizontal and vertical measurements when used with Swiss style total stations that require this offset. Compact and easy to handle: Mini size reduces wind load and makes pole mounting and carrying simpler during long field sessions. Reliable optical : Precision prism element provides consistent returns for clear, repeatable measurements. Durable field use: Built for everyday surveying conditions with a stable housing that resists routine wear and movement. Faster setup and measurement: Simple to position and sight, reducing time required for each control or stakeout point. Features and attributes Function: Acts as a reflector target for total station distance and angle measurements, calibrated to a 17.5mm offset. Compatibility: Designed for Swiss style total stations and any surveying systems that specify a 17.5mm prism offset. Size: Mini form factor for low profile mounting and convenient transport. Material: Includes a precision optical prism element housed in a sturdy, fieldready enclosure. Performance: Consistent optical returns and stable offset alignment to support accurate surveying operations. Practical applications Construction layout and stakeout: Place on a pole to mark gridlines and control points during site layout and building setting out. Cadastral and boundary surveys: Use as a portable target to establish or verify boundary markers with compatible total stations. Topographic and control surveys: Deploy for quick control point measurements and check shots in the field. What you will notice in use Quick alignment and clear signal returns that help reduce rechecks. A compact target that is simple to mount on standard poles and to carry between points. Offset accuracy that integrates directly into measurement workflows for Swiss style total stations. This mini prism offers a focused solution when a 17.5mm offset reflector is required, combining compact size with dependable optical performance for surveying tasks.
