PRL900HT
Bluetooth Rotary Laser

The Plott 900 HT rotary laser is a connected, dual slope rotary laser for precise indoor & outdoor leveling. It enables users to set slope and automatically dials-in the angle of the laser beams on both the x & y axis. Once connected to the free app, users can control rotation speed, scan angles, slope of x & y axis, and many other functions up to 1000 feet away from the laser.

The Overview

Top Of The Line Accuracy

The PRL900HT has accuracies of 1/16” at 100 feet on horizontal applications and  1/8” on vertical applications; with a range of 2,000 feet with detector.  It is ideal for leveling and grading applications for sport fields, parking lots, drive-ways and many more.

Frequently Asked Questions

What makes the PRL900HT different from standard rotary lasers?+
The PRL900HT features long-range Bluetooth 5.0 connectivity. This allows you to control rotation speed, scan angles, and dual-axis slopes directly from the free Plott smartphone app up to 1,000 feet away (when paired with the detector), making it easily operable by one person.
What is the maximum range and accuracy of the PRL900HT?+
It offers top-of-the-line precision with an accuracy of 1/16 inch at 100 feet for horizontal applications and 1/8 inch at 100 feet for vertical applications. When used with a detector, it boasts an impressive 2,000-foot working range.
Can I set custom slopes for grading projects?+
Yes. It is a dual-slope rotary laser, meaning you can automatically dial in the angle of the laser beams on both the X and Y axes up to an 8% slope using the connected app. This makes it ideal for grading driveways, parking lots, and sports fields.
What rotation speeds and scan angles are available?+
You can switch between three rotation speeds (300, 600, and 1200 RPM) and four scanning angles (0°, 15°, 45°, and 90°) directly from the laser's control panel or the smartphone app.
How long does the battery last?+
The PRL900HT features a built-in rechargeable battery that provides up to 20 hours of continuous operation on a single charge.
Do I need to send the laser away to a factory for calibration?+
No. Unlike traditional lasers that require weeks of downtime for mailing and servicing, the PRL900HT can be autonomously calibrated to factory specifications within half an hour at any partner distributor using Plott's Automatic Calibration Station.
