Pacific Laser Systems PLS5 and PLS3 Laser Levels

Introduction

Pacific Laser Systems has long been recognized for manufacturing some of the most reliable and accurate laser levels for professional contractors. The PLS5 and PLS3 Laser Levels are standout tools in this lineup, designed to deliver fast, precise layout and alignment for a wide range of construction and installation tasks. Both models are engineered in the USA, offering rugged durability, intuitive operation, and industry-leading accuracy—key advantages for professionals who demand efficiency and reliability on the job site.

The PLS5 is a five-point laser level, projecting bright, visible laser dots for plumb, level, and square applications, ideal for framing, cabinetry, drop ceilings, and more. The PLS3, with its three-point system, excels at basic leveling, plumbing, and squaring tasks, making it a favorite for steel stud framing, HVAC, electrical, and residential construction. Both tools feature fast, automatic self-leveling, long battery life, and robust water and dust resistance (IP54 rating), ensuring consistent performance even in demanding environments.

The target audience for these laser levels includes contractors, carpenters, electricians, HVAC technicians, and DIY enthusiasts seeking professional-grade results. With an estimated price range of $200–$400,, depending on the model and kit configuration, the PLS5 and PLS3 Laser Levels are competitively priced for their accuracy and durability. They are widely available through major tool retailers and online distributors.

Pacific Laser Systems PLS5 and PLS3 Laser Levels are trusted for their ease of use, rapid setup, and precision—qualities that save time, reduce errors, and boost productivity on any project. Whether you need comprehensive five-point alignment or straightforward three-point leveling, these tools deliver the performance professionals rely on every day.

Safety Labeling & Instructions

The PLS5 and PLS3 contain a semiconductor laser diode with a wavelength of 635 nanometers.
The continuous output of any single beam never exceeds 1.0 milliwatts. Never stare directly into the laser beam or view the beam with optical instruments. Turn the laser off when not in use.

CAUTION: USE OF CONTROLS, ADJUSTMENTS, OR PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
These labels are attached to every PLS laser. These are not to be removed or defaced.

Beams

PLS5 The five beams of the PLS5 are: #1 Forward Beam, #2 Down Beam, #3 Up Beam, #4 Left Beam, #5 Right Beam. All PLS5 beams have the same brightness and are square to each other.

PLS3 The three beams of the PLS3 are: #1 Forward Beam, #2 Down Beam, #3 Up Beam.

Plumb

To establish plumb with the PLS5 and PLS3, place the #2 down beam over the mark to be transposed. See Fig.1. The #3 up beam is exactly plumb within specification. You can shoot plumb marks down and up, or cantilevered over the edge of a building/shaft opening or floor track, etc. See Fig.2. Use the floor stand with your PLS5 or PLS3 to increase the sight angle of the #2 down beam.

The PLS3 and PLS5 can quickly survey existing conditions for plumbing. Use a tape
and #3 up beam. Position the laser near the structure.

Check any distance up or down the structure. It is also possible to transpose marks from a roof or ceiling down to the floor. Move the laser until the #3 up beam hits the edge or center of the ceiling component to be transposed. Mark the floor at the #2 down beam. See Figs. 2 and 3.

Precise level and grade marks are easily established with the PLS5 and PLS3. Swivel the unit about its center, stopping to mark the desired level or grade points. See Fig. 4. Any stable surface can be used. When mounted on a tripod or wall mount, swivel and mark.

See Fig. 5. When turning your PLS5 or PLS3 on a tripod,, be sure the tripod head is perfectly level. An error in marks can result in the tripod being out of level.

To survey existing conditions for the level, point in the direction to survey. Using a tape or rod with a benchmark, the variations in level or grade can be noted quickly at various distances. See Fig. 6.

Square

To establish the square, place the PLS5 with the #2 down beam over the layout reference line. See Fig. 7. Place the pendulum target on that line, and center #1 forward beam on the center of the target. Once centered, move the pendulum target to square on #4 left beam or #5 right beam. Make a mark on the floor or surface near the laser,, and the second mark at the desired distance from the laser. See Fig. 7.

Magnetic Bracket Instructions

To use the magnetic bracket with the PLS laser:

Screw the 1/4 x 20 threaded knob to the mount on the base of the PLS laser.
Mount the PLS laser and bracket to steel studs, steel door frame, I-beams, carpenter’s square, etc.
Rotate the PLS laser tthe o the desired point and make your mark.

Combine the PLS laser, the magnetic bracket, a standard steel carpenter’s framing square, and one or more clamps,s and can mount the laser in unlimited ways. Clamp carpenter’s square to concrete forms, ladders, wood studs, etc. Attach the PLS laser with the magnetic mount as described above. If you drill two small holes centered on the long section of the carpenter’s square, the square can be attached to unfinished drywall partitions with screws or removable nails. Slide the PLS laser up and down the mounted carpenter’s square to the precise desired height.

Pendulum Target

Use the PLS5 pendulum target for a variety of time-saving alignment tasks. For square: For consistent accuracy in establishing or checking the square, use the PLS5 target to transfer the laser beam to the floor surface. To establish a square, see page 8 of this manual. Always mount the PLS5 laser on the floor stand when establishing a square. The pendulum target is designed so the beams are best seen at this height.

For transfer of vertical lines:
To transfer vertical marks quickly and accurately to a wall:

Place the front of the PLS5 laser against the wall with the #1 forward beam on the mark to be transferred. (If the mark is on the floor, place the #2 down beam over the mark.)
Place the target with its back flat against the wall at the desired height and move the target until the #3 up beam is centered on the plastic-lined target.
Mark the top or bottom of the target arrow pins.

PLS5 System Interior - Exterior System

The PLS5 is the only point-to-point layout tool for use on both indoor and outdoor job sites. Bright sunshine has traditionally limited the use of visible beam lasers to interior projects. The PLS5 partnered with our laser receiver gives the contractor the ability to accurately lay out a job site up to 250 + feet, even in the brightest outdoor conditions.
The PLS5 can also be used inside, without the receiver, for all point-to-point alignment tasks.
