Topcon LN-1000i Layout Navigator

The LN-1000i Layout Navigator features one-person, self-leveling setup, reflectorless measurement, and camera-guided targeting. It can operate in congested spaces and measure points reflectorlessly up to 50 meters (164 feet) away, reaching difficult overhead areas with an extended vertical range. It allows work directly from digital plans to reduce layout errors and eliminate manual calculations. Instead of relying on estimations, you can see your target point clearly through the integrated camera and lock onto a prism instantly. The high-visibility green laser makes point identification easier in bright indoor environments, ensuring meeting accuracy requirements with confidence. The entire process connects your digital plans to the field through Topcon Digital Layout software, which simplifies calculations and creates a reliable record of your work.

Features:

• Reflectorless measurement: Capture points up to 50m away without a prism

• Integrated camera: See your target point and lock on instantly

• One-person, self-leveling setup: Start working faster with automated instrument setup

• High-visibility green laser: Identify layout points clearly even in bright interior environments

• Topcon Digital Layout integration: Connect your digital model directly to the field

• IP65 durability and external power option: Operate reliably in tough job site conditions for longer
