The Stabila 05700TR LAR 350 Rotary Laser Kit is a fully automatic rotary laser package built for contractors who need accurate long-range leveling, grading, and alignment on active jobsites. This is a rotary laser designed for horizontal leveling, vertical layout, and dual-slope site work. Model Number: 05700TR. If you are laying out foundations, checking elevations, setting forms, or handling exterior grading, this is the kind of tool that saves repeat trips and cuts down on rework.

What separates this unit from a basic construction laser is the dual-axis slope control. The LAR 350 lets you set controlled inclination up to 5° on two axes, which is a big deal for drainage runs, sloped concrete prep, landscape grading, and any layout where level is not the target. It is also built for both horizontal and vertical applications, so one tool covers standard level work, vertical alignment, plumb reference, and right-angle layout.

STABILA also built in MOTION CONTROL, which gives you remote operation in a way that is faster than walking back to the tool every time you need an adjustment. On a big site, that is not a gimmick. It means one person can fine-tune the laser position or settings without burning time crossing the slab over and over. The LED ASSIST system adds another layer of practical usability by showing operating status and axis information clearly, which helps when conditions are noisy, busy, or bright.

Accuracy and range are where a rotary laser either earns its keep or becomes a headache. The listed leveling accuracy of ±1/8 in at 100 ft gives you the precision needed for construction layout, and the working area diameter up to 2600 ft with the REC 300 Digital receiver makes this a serious option for large interior and exterior work. The receiver does more than just catch the beam, too. It provides visual and acoustic guidance and shows distance to grade, which helps you move faster when setting elevation or checking deviation.

On the durability side, the housing is clearly aimed at real field conditions. STABILA's PROTECTOR system is designed to protect the laser even if it falls from a tripod up to 6 ft, and the IP 65 rating means the unit is sealed against dust and water. That matters if you are working around mud, rain, concrete dust, or rough site conditions where delicate tools do not last long. The long operating life of up to 80 hours also means less downtime and fewer battery swaps during extended layout work.

This kit is not just the bare laser. It comes as a full job-ready setup with the REC 300 Digital receiver, RC-LAR350 remote control, heavy-duty tripod, elevation rod, 90° angle mount, target plate, laser goggles, carrying case, and batteries. That makes it a better fit for crews who want to get to work right away instead of piecing together accessories separately.

The Stabila 05700TR LAR 350 Rotary Laser Kit makes the most sense for concrete contractors, site crews, excavators, general contractors, masons, and commercial framing teams who need dependable exterior and interior layout over larger areas. If your work is mostly short indoor punch-list tasks, this is more laser than you need. But if you are running layout across a building shell, slab, foundation, or grade, this is the kind of rotary laser that pays for itself in accuracy, range, and time saved.

Stabila 05700TR LAR 350 Rotary Laser Kit is the real-deal site laser

If you need one rotary laser that can handle large layout, controlled slope work, and rough site conditions, this is one of the strongest options in the category.

• Who it's for: Contractors doing concrete, site prep, foundation work, grading, and large-scale interior or exterior layout.
• Why it stands out: Dual-axis slope, remote operation with MOTION CONTROL, long 2600 ft working diameter with receiver, and IP 65 durability make it more than a basic level-only laser.
