Rotary Laser Level 99-028K Dual Slope Self-Leveling - Contractor Ready

In this review of the 99-028K rotary laser level, the bottom line is simple: it is built for contractors and advanced users who need reliable, fast layout both indoors and outdoors. The single biggest reason to buy is its programmable dual-slope capability combined with dependable self-leveling, which removes mental math when setting grade and makes complex slope work far quicker. Reviewers and jobsite users will appreciate the solid kit that comes ready for daily use and long runs of work.

Key Features

• Self-leveling horizontal and vertical: Ensures accurate horizontal planes and vertical alignment for fencing, footings, drywall track, and more without fiddly manual adjustments.
• Programmable dual-slope: Lets operators set two-axis slopes up to 5 deg. to check grade or establish drainage lines without separate calculations.
• Visual and audible alarms: Alerts with a flashing beam and siren if the unit is out of leveling range, protecting accuracy and safety on uneven ground.
• Complete kit included: Comes with a rechargeable NiMH pack, charger, detector with clamp, tripod, 13 ft grade rod, remote, tinted glasses, and a hard-shell case for organized transport.
• Worksite durability: Designed as the workhorse of the line, it stands up to contractor and excavator tasks while offering the precision needed for flatwork and landscaping.

Who It's For

This laser is best for flatwork contractors, landscapers, and excavators who need a robust rotary laser capable of long-range performance and programmable slope work. It suits users who perform both vertical layout tasks-like post and footing alignment-and large horizontal site grades.

It is less appropriate for casual DIYers who only need simple, short-range leveling or prefer a pocket-sized unit; the 99-028K is a heavier-duty kit intended for frequent jobsite use and comes with accessories that assume a professional workflow.

Pros & Cons
