Product Introduction
The N3 Laser RTK, equipped with Sinan's proprietary side-laser technology and a millimeter-accuracy laser module, offers a measurement range of up to 30 meters. Featuring carefully selected Class 3R green light that remains clearly visible even in bright conditions, it provides 360° panoramic measurement for an unparalleled working experience. With point-to-surface stakeout capabilities, it measures wherever the laser points, conquering complex environments and mastering the field of surveying.
Proprietary Side Laser Technology
Features carefully selected Class 3R green light that remains clearly visible even in bright conditions, with a millimeter-precision laser module embedded on the side, offering a measurement range of up to 30 meters.
360° panoramic measurement
Offers a unique working experience. With point-to-surface stakeout measurement, it's contactless and faster. Whether it's hazardous, complex, or indoor locations, simply point the laser and have precise measurements at your fingertips.
Inertial Navigation System (INS)
No initialization required-ready to use right out of the box. Tilt measurement and point-and-measure functionality for greater efficiency.
