The pairing
The laser puts up a green line. The HL760U reads it and talks back.
HV1305GC
It puts a green reference up.
- Green beam (510–530 nm) for interior layout you can see.
- Horizontal or vertical: it senses which way it stands and self-levels within ±5°.
- 1/16″ at 100 ft, 0 to 600 rpm, scan lines of 5° to 90°.
- Plumb up and plumb down dots for point transfer and 90° layout.
- The RC1402 remote or the free Laser Remote App runs it from across the room.
HL760U
It reads green and red, and talks to the laser.
- The U means universal: it detects green and red beams (the HL760 is red only).
- A digital readout of how far you are from on-grade, on a 5-inch reception height.
- Two-way radio with the HV1305GC: PlaneLok and automatic Grade Match.
- Ships with its C70 rod clamp. IP67, survives a 10 ft drop onto concrete.
What the two of them do together
Inside, you work right off the green line. When the beam is hard to see — bright rooms, longer runs — the HL760U finds it for you. Because it talks to the laser by radio, it can also lock a vertical line onto a point (PlaneLok) or match an existing slope (Grade Match). For a vertical line, Spectra’s training shows the HL760U on the second point with its light bar facing down toward the ground.
One laser, two jobs
Horizontal and vertical.
HORIZONTAL
Elevation control and manual slope
Standing up, the HV1305GC self-levels and spins a level plane across the site. Read it with a receiver on a rod and every elevation is a number.
- Elevations: footings, foundations, forms and pads
- Grade checks: cut and fill, excavation depth, sub-base
- Manual slope: tilt one axis with the arrows for drainage, driveways and walks while the other axis stays level
- Interior: ceiling grid and raised floors
VERTICAL
Alignment
Lay it on its side and it self-levels a vertical plane, with automatic plumb down to put the beam right over your point.
- Plumb vertical wall setup: plumb walls for buildings and barns
- Retaining walls and fences: one straight line down the run
- Layout: wall and partition lines, floor to ceiling, column and anchor bolt lines
- Forms and panels: concrete forms and tilt-up panels, straight and plumb

Overview
A Green Beam Built for Interior Layout.
Spectra Precision HV1305GC-7 Multipurpose Green Beam Laser
The automatic self-leveling Spectra Precision® HV1305GC is the green beam version of the HV1305C: one rugged laser for horizontal, vertical and plumb work. The green beam is easy to see in brightly lit interiors, so crews lay out walls, transfer points and set ceilings straight off the line. A split beam gives you plumb point transfer and 90° layout.
The HV1305GC-7 is Spectra’s complete interior system: the laser, the HL760U universal receiver, the RC1402 remote, the M304 wall mount, the green ceiling target and green glasses, rechargeable power, and the medium case that has a place for every piece, the wall mount included.
Rugged
Survives drops of up to 3 feet onto concrete and tripod tip-overs up to 5 feet. IP66 dust and water rated.
Phone control
Bluetooth is built in: the free Spectra Precision Laser Remote App runs the laser from your phone. The RC1402 radio remote comes in the kit as well.
Green vs red
Same laser platform as the HV1305C. The green version runs up to 30 hours on the B10 pack (red: up to 45) and pairs with the HL760U, which reads green.
Inside and out
Built for interior layout; with the HL760U it also works outside, out to a 4,000 ft working diameter.
Slope, in plain words: the HV1305GC self-levels, and you can tilt one axis with the arrow buttons (single axis slope) while the other stays level. You cannot type in a grade like 2%. For a dialed-in percentage, you want an automatic grade laser such as the GL412N or the GL1425C. Not sure? Call 1-877-866-5721.

The HL760U — Spectra’s Universal Digital Readout Receiver
A green laser needs a receiver that can see green. The HL760U reads both green and red beams, shows exactly how far you are from grade as a number, and talks to the HV1305GC by radio for PlaneLok and Grade Match.

What the HL760U Delivers on the Job:
- Reads green and red — works with the HV1305GC and any red-beam laser you already own
- Digital readout — the exact distance above or below grade, no sliding the clamp
- 5-inch reception height — catches the beam fast
- Two-way radio with the HV1305GC — PlaneLok and automatic Grade Match from the RC1402 or the app
- Fingerprinting — pairs to your laser and ignores other lasers on the job
- Anti-strobe sensor — no false readings from site strobes
- 10-foot drop rating — onto concrete; IP67
- Ships with the C70 rod clamp — mounts straight to your grade rod
- Light bar down for vertical lines — how Spectra’s training sets it on the second point
The HL760U features a digital readout of elevation on the large front and rear LCDs and shows exactly how far the elevation is from on-grade for fast cut/fill readings. Accurate measurements can be made without moving the rod clamp.
Radio communication allows working with another HL760U or HL760 for long range remote display and monitoring. “Fingerprinting” links the receiver with a particular laser, so it only accepts the laser it is paired with.

Bluetooth Control
Run the Laser From Your Phone.
The HV1305GC has Bluetooth built in. Download the free Spectra Precision Laser Remote App from Google Play or the Apple App Store and your phone becomes the remote. Spectra’s datasheet says the remote control app “allows operation of all laser functions from anywhere on the jobsite” and that the Bluetooth “eliminates the extra cost of the remote control.” This package ships with the RC1402 as well, so you have both.
How far does the app reach? Bluetooth range depends on your phone and the jobsite — expect roughly 100 to 150 ft with a clear line of sight. Need more reach? The RC1402 radio remote works up to 330 ft. (Our field estimate, not a Spectra spec.)
One person, one setup
Why it matters on site
- Change rotation speed, scan size and mask from where you are standing, not at the tripod.
- Set single axis slope and watch the rod while you do it.
- Nothing extra to carry or lose: the phone is already in your pocket.
Error codes in plain words
User guide, chapter 25
- With the app, the explanation of an error code is shown directly on the phone instead of a number to look up.
- Clear it with OK in the app, the same as E on the remote.
Speaks your language
User guide, chapter 18.5
- The app uses your phone’s language when the laser supports it, and English otherwise. No menu to change.
- The laser itself offers 14 languages through the RC1402.
What runs whereFrom the HV1305GC user guide (12/24)

Connecting takes 30 seconds: the steps are further down, in Pair it in 30 seconds ↓
One thing the app will not do on this laser: take a typed grade. The app runs the laser’s functions; it does not let you type in a grade on the HV1305GC. The HV1305GC is a manual slope laser. Tilt one axis with the arrows (single axis slope) and check it on the rod, or let PlaneMatch find an existing grade with the HL760U in this package.

Vertical Mode
Vertical Alignment & Layout Applications
When set in its vertical operating position, the rotary laser establishes a vertical reference plane for layout and alignment on interior and exterior projects. This allows contractors to establish straight building lines, check upright alignment, and transfer wall layout from the floor to the ceiling.
Common applications include:
Wall and partition layout
Establish straight layout lines for framing, interior partitions, and metal stud walls.
Floor-to-ceiling alignment
Transfer wall layout lines from the floor to the ceiling to align upper and lower wall tracks.
Checking walls and columns for plumb
Use the vertical reference plane to check upright alignment during installation.
Concrete form alignment
Align formwork with established building lines and check vertical wall forms for plumb.
Anchor bolt alignment
Keep rows of anchor bolts aligned with the required building reference line.
Fence and post alignment
Establish a straight reference for positioning fence posts along a run.
Façade and exterior panel installation
Provide a reference plane for aligning exterior wall panels and supporting framework.
The 90° Laser Dot, Explained
90° Squaring Using a Visible Reference Dot
With the laser positioned for vertical operation, the stationary reference beam projects a dot at a 90-degree angle to the rotating laser plane. Together, these references can be used to establish square corners for wall layouts, partitions, framing, and concrete forms.
The stationary reference dot cannot be detected by a standard rotary laser receiver. You must be able to see the dot with your eyes on a wall, target plate, or other surface to align and mark its position. This function requires lighting conditions and a working distance that allow the dot to remain clearly visible. Bright sunlight and longer distances can make the dot difficult or impossible to see.
The usable distance for this squaring function is limited by the visibility of the reference dot. The laser’s advertised working range with a receiver does not apply to this stationary dot.
The 90° layout and plumb beam, and the difference between the rotating beam a receiver reads and the stationary dot you align by eye, are described in Spectra’s HV1305C/HV1305GC user guide (12/24, introduction and chapter 21.2) under Downloads.

Walls, a 90° layout off an existing wall and suspended ceilings with the HV1305GC.
Step by Step
Three Interior Jobs, Shot by Shot.
Align a wall between two reference points
1Plumb down over point one
Lay the laser on its side; automatic plumb down puts the green dot right on the first survey point.
2Beam visible? Use the target
Stand the green target on the second point and swing the beam onto it.
3Steer from where you stand
Use the arrows in the Laser Remote App, or the RC1402, without walking back to the laser.
4Hard to see? Use the HL760U
When the beam is difficult to see, put the HL760U on the second point with its light bar facing down and steer until it reads on grade.
5Mark the line
Mark the wall line at the receiver and start the layout.
90° layout from an existing wall
1Set up at the wall
Set the laser on its side near the reference wall.
2Measure near
Measure from the plumb-up dot to the wall close to the laser.
3Measure 5–10 ft away
Measure again farther down the wall. Same distance = parallel to the wall, ready for layout.
4Scan mode from the app
In bright rooms, set a scan line (Line Size) from the app so the beam shows where you work.
5Mark the 90° line
Mark the line on the floor for track or framing. No chalk lines, no string.
Suspended ceiling installation
1Hang it on the M304
Mount the laser on the M304 wall mount (in the kit), fixed to a stud or framing member at ceiling height. The floor stays clear.
2Set the height
Hold the green target at the laser and set the beam to your ceiling height.
3Scan from the remote
Turn on scan mode from the RC1402 or the app to put a bright line where you are working.
4Target on the grid
Clip the Q104124 magnetic target to a grid component and set main runners to the beam.
5Check it across the room
One setup covers the room; check each runner against the target without walking back to the laser.

How It Works
Level, Vertical and Plumb — From the Keypad or Your Phone.
Press the power button and the HV1305GC always starts in automatic self-leveling. It works out for itself whether it is standing up (horizontal) or on its side (vertical). The green LED flashes once a second while it levels, the rotor starts when it is level, and it comes back at the last speed you used.
Rotation, scan and point
Rotation button: 0, 10, 100, 200, 300, 600 rpm. Scan button: 5°, 15°, 45° or 90° lines for visibility. At 0 rpm the arrows point the beam anywhere around 360°.
Manual and single axis slope
Press Manual once and the arrows tilt both axes by hand. Press it twice for Y single axis slope (three times for X): one axis tilts, the other keeps self-leveling. Red and green flash together. No grade number is entered.
Vertical: line scan and plumb down
On its side it self-levels vertical. Press Left and Right together for Line Scan to centre the beam. At 0 rpm it drives the beam to plumb down over your point, within 1/4 in at 4 ft.
HI alert, mask and standby
Bump the tripod and it stops and warns you (delay 5 min or 30 s, set from the remote). Mask mode shuts the beam off in up to 3 sectors. Hold Manual 3 s for standby at lunch: beam off, HI alert still on.
Horizontal, outdoors — on site
Find your height of instrument (HI).
1
Set up and let it level
Tripod on firm ground, laser on top, power on. Wait for the solid green LED.
2
Read the benchmark
Put the rod with the HL760U on your benchmark and slide the receiver until it reads on grade.
3
Add it up
HI = benchmark + rod reading. Spectra’s example: 100.23 ft + 4.34 ft = 104.57 ft.
4
Work from the HI
Every other elevation on the site is HI minus the rod reading there.
Vertical, outdoors
Line up two points: forms, fences, anchor bolts.
1
Lay it on its side
On the tripod’s vertical 5/8 x 11 mount, roughly over your first point.
2
Plumb down
Set 0 rpm: the beam drives to plumb down so you can put the laser right over the point.
3
Swing the line
Line Scan centres the rotor; Left and Right move the vertical plane until it hits your second point.
4
Mark and build
Set the rotation or scan and mark the line along the forms, footing or fence run. Watch the X axis: in vertical it has no drift sensor.
Interior
Points, walls and ceilings.
1
Ceiling grid: mount it on the wall molding
Install the first piece of molding at finished ceiling height, slide the wall mount over it and lock it. Turn the fine height screw until the slider edge sits on the 0 mark, then tighten the locking knob (user guide 22.1).
2
Walls and partitions: set over the near control point
Put the laser over the near wall control point. With the wall mount on the floor track, set it to the edge of the track (the 0 mark) (user guide 22.2).
3
Point to the far control point
Use the Left / Right arrows to point the beam at the far wall control point, then walk to it and fine-tune the line from the remote until the beam is on the mark. For the 90° beam, Beam Plunge on the RC1402 moves it to your mark (user guide 22.2).
4
Mark the track, floor and ceiling
Press Manual after the line adjustment so the laser re-levels, then mark or install the track line on the floor and the ceiling (user guide 22.2).

Two Things Worth Knowing.
Manual slope means you tilt it, not type it
The HV1305GC self-levels, and single axis slope lets you tilt one axis with the arrows while the other stays level. The app runs the laser’s functions; it does not let you type in a grade on the HV1305GC. For a dialed-in percentage, look at the GL412N or GL1425C grade lasers.
Check it before the job, and after any drop
Calibration is the owner’s job, not the warranty’s. Spectra’s check: set up 100 ft from a wall, mark the beam on both ends of each axis; more than 1/8 in apart means it needs calibrating. It is step by step in the user guide under Downloads.

QUESTIONS & ANSWERS
HV1305GC-7 Questions We Actually Get.
Grouped so you can find yours. Buying questions first, then how to work it, then what to do when something is wrong. Every HV1305GC error code is under Troubleshooting.
Before You Buy 15
What is the Spectra HV1305GC-7?
Spectra’s own HV1305GC green beam package: the self-leveling horizontal / vertical laser with the HL760U universal receiver and C70 clamp, the RC1402 remote, the M304 wall mount, the Q104124 green target, Q104252 green glasses, the B10 rechargeable pack and charger, and the 100981-00 medium case.
Green or red: which should I buy?
Green (HV1305GC) is easier to see indoors, so it suits interior layout where you work off the visible line. Red (HV1305C) runs longer on a charge (up to 45 hours vs up to 30) and suits general site work. Accuracy, range and toughness are the same.
Will my HL760 receiver read the green beam?
No. The HL760 reads red beams only. The HL760U in this package reads green and red, so it works with this laser and any red laser you already own.
How far does the HV1305GC reach?
Up to 500 ft (150 m) visible, and a 4,000 ft (1,200 m) working diameter with the HL760U receiver: 2,000 ft from the laser in every direction (Spectra).
How does it compare with a line laser?
Spectra rates the HV1305GC at up to 4 times the accuracy of standard line lasers (1/16 in at 100 ft) and up to 5 times the working range: 500 ft visible and 4,000 ft with a receiver.
What if I cannot see the beam?
Use the HL760U. Put it on your point with the light bar facing down and steer the laser until the receiver reads on grade, then mark at the receiver. It detects the beam even where your eye cannot.
Does it do PlaneLok and Grade Match?
Yes. The HL760U talks to the HV1305GC by radio, so it does PlaneLok and automatic Grade Match (PlaneMatch), out to 260 ft. Start them from the RC1402 or the Laser Remote App.
How long does the battery last?
The B10 NiMH pack runs the HV1305GC up to 30 hours and recharges in under 10 hours, in or out of the laser.
What if I forget to charge it? Am I out of business for the day?
No. Lift the B10 pack out and four D-cell alkaline batteries go straight into the battery compartment. D cells are not part of the kit; they are simply what the laser also accepts. Never put alkaline cells inside the B10 pack’s own cage.
Why the medium case?
The 100981-00 medium case has a designated slot for the M304 wall and ceiling mount that comes in this kit. The small case has no room for it.
How do I set a suspended ceiling with it?
Hang the laser on the M304 wall mount at ceiling height, clip the Q104124 green target to the grid, and use scan mode from the RC1402 or the app to put the beam on the target.
How do I align a wall between two reference points?
Use automatic plumb down to put the laser over the first point. If the beam is hard to see, put the HL760U on the second point with its light bar facing down toward the ground, then steer the laser with the arrows in the app while you watch the receiver.
Is this Spectra’s package or a Contractors-Tools.com kit?
It is Spectra’s own HV1305GC-7 package (July 2026 catalog, page 14).
What is the warranty?
5 years on the HV1305GC laser for materials and workmanship (calibration is not covered) and 3 years “No Excuses” on the HL760U receiver.

Using It 10
Can I control it with my phone?
Yes. Install the free Spectra Precision Laser Remote App, turn on the phone’s Bluetooth and location, and start the app within 30 seconds of switching the laser on. The laser’s LED turns blue when it connects.
Which phones does the Laser Remote App work on?
Android and iPhone. The Spectra Precision Laser Remote App is free on Google Play and the Apple App Store. The first time you open it, accept the license and turn on the phone’s GPS and Bluetooth.
How far away does the Laser Remote App work?
Bluetooth range depends on your phone and the jobsite — expect roughly 100 to 150 ft with a clear line of sight. Need more reach? The RC1402 radio remote works up to 330 ft. That is our field estimate from using these lasers; Spectra does not publish a Bluetooth range for the HV1305GC.
Do I still need the RC1402 remote if I use the app?
For everyday work, no: Spectra says the app allows operation of all laser functions from anywhere on the jobsite. Three things are RC1402 only in the user guide: changing the radio channel, the Info menu (runtime, firmware, serial number) and the remote’s own backlight. This package includes the RC1402 as well.
Can I type a grade into the Laser Remote App?
No. The app runs the laser’s functions; it does not let you type in a grade on the HV1305GC. Tilt one axis with the arrows (single axis slope) and verify on the rod.
Can a laser receiver pick up the 90° squaring dot?
The stationary reference dot cannot be detected by a standard rotary laser receiver. You must be able to see the dot with your eyes on a wall, target plate, or other surface to align and mark its position. This function requires lighting conditions and a working distance that allow the dot to remain clearly visible. Bright sunlight and longer distances can make the dot difficult or impossible to see. The usable distance for this squaring function is limited by the visibility of the reference dot. The laser’s advertised working range with a receiver does not apply to this stationary dot.
How do I use it vertically?
Lay it on its side on the vertical 5/8 x 11 mount and switch on: it detects vertical and self-levels. Press Left and Right together for Line Scan, move the plane with the arrows, and set 0 rpm for automatic plumb down over your point.
What happens if someone bumps the tripod?
The HI alert stops rotation, turns the beam off and sounds a warning when the laser height changes by about 3 mm (1/10 in), so you do not keep working off a bad setup. Set the delay to 5 minutes (default) or 30 seconds from the remote.
Can I keep the beam off other crews’ receivers or windows?
Yes. Mask mode shuts the beam off in up to 3 of the 4 sectors. It always powers up with mask mode off.
How do I check calibration?
Set up 100 ft from a wall, mark the beam on the +Y and -Y sides, then the X axis. If the marks differ by more than 1/8 in at 100 ft, it needs calibrating. The full procedure is in the user guide under Downloads.
