Prism Assembly & Target (Single-Tilt Reversible Dual-Offset)

Description

The Professional Single-Tilt Surveying Prism Assembly & Target is a high-accuracy optical reflector engineered for precise EDM distance measurements. Featuring a reversible holder that quickly toggles between 0mm and -30mm offsets, this heavy-duty target is fully compatible with Topcon, Sokkia, Trimble, and Leica total stations. Built with a rugged aluminum target plate and a sealed 64mm copper-coated prism, it guarantees stable long-range returns in demanding field conditions.

Dual-Offset Versatility For Seamless Integration

Eliminate math errors in the field with the Reversible Dual-Offset Prism Target, which is designed to fit standard surveying workflows. The metal prism holder easily unscrews and reverses to switch from a 0mm constant to a -30mm absolute offset. This functionality allows a single crew to swap between various hardware ecosystems without needing separate reflectors or confusing offset recalibrations in the data collector.

Long-Range Clarity & Rigid Alignment

The core contains a premium, high-density 64mm optical glass prism backed by a copper-reflective coating. This design minimizes signal dispersion, maximizing your total station’s EDM tracking distance and performance in thick haze or high-glare environments. The high-visibility, contrast-heavy target plate features explicit sighting marks for rapid manual aiming across long baselines.

Key Features:

• Dual-Option Holder: Easily flip-mount the assembly to achieve 0mm or -30mm constants.
• Copper-Coated Optics: Heavy-duty internal reflective coating prevents moisture fogging and maximizes distance returns.
• Lockable Tilting Axis: Equipped with an oversized brass friction knob to firmly clamp the target at vertical or angled positions.
• Universal Thread Mount: Built-in 5/8″ x 11 bayonet base installs onto standard range poles and tribrach adapters.
• All-Weather Target Plate: Hardened aluminum alloy plate resists bending, wind-shake, and UV fading.

Professional Applications:

• Topographic Mapping: Deliver crisp, clean points to your total station over extended ranges.
• Construction Layout: Achieve precise corner staking and utility placement using the zero-offset mode.
• Boundary Surveys: Secure high-accuracy property lines using industry-standard -30mm configurations.
• Monitoring Sessions: Lock the tilting axis into fixed positions on control points for long-term settlement analysis.

📐 Pro Tip: When setting up for a zero-offset configuration, verify that the “0mm” stamp face on the tilting yoke is oriented directly toward your instrument to prevent horizontal error.
