| The Plott PRL900HT-R puts premium dual-slope rotary laser technology in the hands of contractors who are done paying premium prices to get it. With built-in Bluetooth, a free smartphone app, and the ability to dial in slope on both the X and Y axis simultaneously, this red beam laser handles everything from drain fields and parking lots to athletic fields and driveway grades: all controlled from your phone up to 1,000 feet away when paired with the included detector. It self-levels automatically up to plus or minus 6 degrees, fires to a 2,000 foot working diameter, and runs 20 hours on a single charge. This is a working contractor's laser: no fluff, no compromise, and priced where it should be. |

ONE LASER. EVERY GRADE. Most job sites throw multiple grades at you in a single day — drainage swales, parking lot crowns, driveway approaches, building pads. The PRL900HT-R lets you dial in both the X-axis and Y-axis slopes independently, up to 8 percent on each, without swapping equipment or resetting from scratch. Type your grade percentage directly into the app, hit complete, and the laser physically tilts to your target angle within seconds. Save your most-used settings as presets : next time you're back on that 2 percent drainage job, one tap gets you there.
TURN A TWO-PERSON JOB INTO ONE. Connect your phone directly to the laser for a 200 foot control range, or pair through the included detector for a full 1,000 foot Bluetooth radius. From the app you can change rotation speed, adjust scan angles, toggle slope settings, and even manage your HI alert : all without anyone walking back to the instrument. One person on the rod, one person running grade. Or one person running the whole operation.
POWER ON. SHOOT GRADE. DONE. Electronic self-leveling means the PRL900HT-R is ready to work the moment you turn it on. If a truck drives by and rattles your tripod, the HI Alert bump sensor detects the movement, alerts you on the phone app, and resets the laser before your crew has a chance to shoot a bad reading. That kind of automatic error-catching is the difference between a job that flows and one that has to be re-done.
CONTROL YOUR JOB SITE WITH SCAN ANGLES. Running multiple lasers on a large site? Use adjustable scan angles — 0 degrees, 15 degrees, 45 degrees, or 90 degrees — to isolate each laser's sweep zone so detectors don't pick up the wrong signal. Set one laser sweeping the north half, another at 90 degrees on the south. No interference, no confusion, no bad cuts. Accessible from the laser buttons or instantly from the app.
CALIBRATION THAT DOESN'T SIDELINE YOUR LASER. The PRL900 series supports autonomous calibration at Plott partner distributor stations — back to factory specification in about 30 minutes on-site, not weeks at a service center. For a contractor running a tight schedule, that difference is measured in projects, not hours.
2,000 FEET OF WORKING RANGE. Large site grading, athletic field layout, open lot development — the PRL900HT-R's 2,000 foot working diameter keeps up with your biggest jobs. The included PLLD detector captures the beam reliably at range and extends your Bluetooth app control to the full 1,000 foot radius at the same time.

| Included : Plott PLLD Detector Overview |
|
The included Plott PLLD Detector is more than just a signal catcher — it's the link that makes the entire Bluetooth control system work at full range. A direct phone-to-laser connection covers about 200 feet. Connect through the PLLD and that range extends to a full 1,000 foot radius. The detector connects to the laser, your phone connects to the detector, and you've got complete control of slope settings, rotation speed, scan angles, and HI alerts from across the largest sites — all from your phone.

| Contractor Tips : Getting the Most from Your PRL900HT-R |
- Save Your Slope Presets. If you're regularly running the same grade : say 2 percent for drainage or 1.5 percent for a standard driveway — save it as a preset in the app. Next time you're on that site, one tap dials it in.
- Use Detector Bluetooth for Solo Operations. Connect your phone through the PLLD to get the full 1,000 foot control range. Walk out to the rod location, read the detector, and adjust grade from your phone : no second person needed at the instrument.
- Use Scan Angles When Running Multiple Lasers. Set each laser to a different scan angle so their detection zones don't overlap. Keeps detectors from picking up the wrong signal when multiple crews are working the same site.
- X Runs Side to Side, Y Runs Front to Back. When dialing in dual slope, the X-axis runs horizontally left to right through the laser, while the Y-axis runs front to back through the unit. Keep this picture in mind when setting compound grades.
- Switch to Expanded Detector Mode for Long Range. At greater distances the laser beam naturally spreads slightly. If the detector is struggling past 500 feet, toggle to expanded accuracy mode on the PLLD to widen the capture window.
- Reset from Normal Mode. After setting a slope, return to Normal Mode in the app and the laser self-levels back to zero degrees automatically : no manual adjustment needed.
