Drainage that actually drains

Type the grade in on both axes and the laser holds it. No distance-versus-height math at the stake.

Match the grade that is already there

GradeMatch measures the slope between two points for you, so tie-ins come out right the first time.

Built for the jobsite it lives on

Survives a 3 ft drop onto concrete and a 5 ft tripod tip-over, sealed to IP66.

The pairing

The laser sets the grade. The CR700 reads it, on the rod or the machine.

GL1425C

It puts the grade up.

Dual grade. Enter a grade on the Y and the X axis; it self-levels to both.
1/16″ at 100 ft level, 1/8″ at 100 ft on grade. 300 / 600 / 900 rpm.
Typically ±9% per axis, up to ±15% with pre-tilt.
Bluetooth built in for the Spectra Precision Laser Remote app, plus the RC1402 remote.
HI alert: bump the tripod and it stops and warns you, instead of letting you work off a bad setup.
A 3 ft drop onto concrete, a 5 ft tripod tip-over, sealed to IP66.

CR700

It goes on the rod or the machine.

Rod or machine. The C70 clamp puts it on a grade rod; the C71 magnetic mount puts it on the machine.
A digital readout of how far you are from on-grade.
Two-way radio with the laser: GradeMatch and PlaneLok both work with it.

What the two of them do that neither does alone

GradeMatch measures an existing grade between two points, typically up to 260 ft, and sets the laser to it. PlaneLok locks the beam onto a receiver at a fixed point so wind, vibration and temperature cannot move your grade. Both need the laser and the receiver talking over radio, and that pairing is already done for you in this kit.

Spectra Precision GL1425C-28 dual grade laser package

The GL1425C-28 package. GL1425C Dual Grade Laser Transmitter / CR700 Machine Mount or Rod Mount Receiver / LARGE 5-inch Reception Height / with C70 Rod Clamp and C71 Magnetic Machine Mount / 105516 Vertical Adapter for HL Receiver / RC1402N Remote Control.

Overview

One Laser. Level, Grade and Plumb.

The automatic self-leveling Spectra Precision® GL1425C dual grade laser is the most rugged, cost-effective laser that does three jobs—level, grade, and vertical alignment. Even in harsh jobsite conditions, the GL1425C delivers consistently reliable and accurate performance, enabling you to work faster and smarter. The GL1425C has Bluetooth built in so it can work with the Spectra Precision Laser Remote App and eliminate the cost of the remote control. The laser can be controlled with your smartphone.

The rugged GL1425C laser can withstand drops of up to 3 feet onto concrete and tripod tip overs up to 5 feet. This strength, combined with full weatherproofing and dustproofing, reduces downtime and lowers repair costs over the life of the product.

The GL1425C has options for receivers. The advanced Deluxe CR700 Multi-User Digital Readout receiver provides automatic Grade Match which allows measurement of unknown grade values between two points over unknown ground and eliminates time consuming slope calculations. PlaneLok automatically locks on to an existing elevation or vertical alignment point which eliminates all drift or possibility of error due to improper calibration or weather. This CR700 is optimal when a machine mounted display elevation is required.

GL1425C-28

Why this kit

One receiver for the rod and the machine.

The CR700 does everything a rod receiver does — digital readout, GradeMatch and PlaneLok over radio — and then the C71 magnetic mount puts it on the machine. One receiver, two jobs.

This kit reads in INCHES. Need tenths of a foot instead?

The GL1425C-18 is the identical kit with the grade rod in tenths. Ordering the wrong scale is the most common reason a kit comes back.

GRADE

Grade, Three Ways — Type It, Step It or Snap It.

The GL1425C takes a grade in each axis and self-levels to it. Spectra’s user guide gives three ways to get the number in, from the keypad, the RC1402 or the app.

⌨︎

Digit Select — type the exact grade

Press M, choose Grade, press E. The arrows move the cursor and change each digit; tap Manual to jump between Y and X; press E to set it. Flashing “A” symbols mean it is still leveling to your grade.

M › GRADE › E

⇅︎

Step & Go — nudge it

Hold an arrow for about three seconds and the grade steps up or down: Up and Down for Y, Left and Right for X. Let go and the laser re-levels to the new value.

HOLD AN ARROW

⚡︎

Quick Change — whole percents

Press Up and Down together (or Left and Right) and that axis jumps to 0%, then changes in 1% steps. The fast way to rough in a grade.

BOTH ARROWS

∟︎

Steeper than 9%

Above about 9% the rotor runs out of travel; the laser beeps and shows which way to tilt. Raise or lower one tripod leg (or use the M401 tilting base) to reach up to ±15%.

PRE-TILT

The number almost nobody lists

Grade range: ±9% per axis, ±15% with pre-tilt

Up to about 9% the GL1425C reaches the grade on its own. Past that the rotor head runs out of travel; Spectra’s user guide says to tilt the laser toward the slope with one tripod leg (or the M401 tilting base), and then it reaches ±15% on each axis.

THE RECEIVER

The CR700 Reads It on the Rod or the Machine.

Spectra CR700 Machine or Rod Mounted Laser Receiver — INCLUDED in GL1425C-28 Package

1.5 mm/30 m | 1/16" @ 100 feet | 10 arc seconds

The CR700 has the same “light bar” technology included in HL receivers and delivers extremely accurate and consistent results. Super bright directional LEDs are ideal for entry-level machine grade display that provide instant grade information to the operator and eliminates the need for a rod man in the trench.

CR700 Combination Laser Receiver Unique Functions: LARGE 5-INCH RECEPTION HEIGHT

Bright LED Arrow Displays — Super bright Red/Green/Blue LED arrows visible in all conditions

Magnet Mount for Machine Mounting — C71 Magnetic Mount is 25% Stronger; will not slip on the machine

CR700 Machine Display Laser Receiver Applications

Backhoe, Skid Steer or Mini-Excavator for Grading or Excavating

Grade Rod Mounted Receiver for Elevation Control

Vertical Alignment

Digging footings • Basement excavation • Checking sub-base materials

Setting and Checking elevations • Leveling and Aligning forms • Screeding concrete

GL1425C laser when used with the CR700 DRO receiver, several advanced features can be utilized:

Grade Match: Wireless communication between the CR700 receiver and the transmitters provide automatic Grade Match which connects different elevations and will actually calculate and display grade values between two points when using the GL1425C, GL412N and GL422N.

PlaneLok: For applications that require maximum stability and accuracy is available on the horizontal Y-axis and in both vertical planes. PlaneLok automatically locks the beam on the receiver and keeps it on-grade, reducing typical environmental factors that may induce an error. PlaneLok for vertical alignments provides quick, accurate set-up and easy control. Also provides the ability to quickly set up a vertical plumb or slope reference.

Paired with the GL1425C, the receiver works across the laser’s 2,600 ft working diameter; its radio link to the laser reaches up to 330 ft.

Hover any photo to enlarge it.

It is not locked to this laser, or to this brand

It reads any red beam rotary laser you own.

The CR700 is a red beam receiver. Put it in front of any red beam rotary laser and it reads the beam, whatever badge is on the case.

What changes is the radio. Paired with the GL1425C, the two talk to each other, and that is what turns on GradeMatch and PlaneLok. With any other laser you simply read grade the ordinary way. So the money goes in once.

Range and accuracy, together

One setup for the whole site — and the grade is still right at the far edge.

The GL1425C works across a 2,600 ft working diameter. Set it once and cover ground that would otherwise cost you three or four moves.

And it holds 1/16 in at 100 ft level and 1/8 in at 100 ft on grade, while the HL760 reads down to about 1/32 in on its finest setting.

That combination is the whole point. Range without accuracy is just a long way to be wrong.

Why fewer setups means fewer mistakes

Every time you move a laser you re-establish your height of instrument, and every move is a chance to be a fraction out. Cover more from one position and you carry one benchmark across the job.

Accurate the first time is cheaper than accurate the second time.

IN THE MANUAL

Six Things in the Owner’s Manual Most Sellers Never Mention.

⚠︎

It stops itself when the tripod gets bumped

Once the HI alert arms (5 minutes by default, or 30 seconds), a change of about 1/8″ stops rotation, turns the beam off and sounds a warning. Error 120 on the screen.

HI ALERT

🌡︎

It re-checks itself when the temperature changes

A temperature reference check runs when you enter a grade and again after a 9°F change inside the laser, so a cold morning and a hot afternoon read the same.

TEMP CHECK

⎗︎

It remembers yesterday’s grade

By default it starts on the last saved grade. Sharing the laser between crews? Set Settings › Start Grade › 0 Grade so nobody inherits someone else’s number.

START GRADE

◼︎

It can blank out windows and other crews

Mask mode turns the beam off in up to three of the four quadrants: no false readings off glass, no beam in a neighbor’s receiver.

MASK MODE

⏸︎

It can pause at lunch without losing the setup

Hold Manual for 3 seconds: leveling and beam stop, settings stay, and the HI alert keeps watching. Hold it again to resume.

STANDBY

⚖︎

Sensitivity can be set for wind

Low for wind and vibration, Middle (default), High for calm days. Fewer nuisance re-levels on a gusty site.

SETTINGS

Worth Knowing

Before It Comes Out of the Case.

Worth knowing before it comes out of the case

It always wakes up level

Every power-on starts in automatic self-leveling, and it decides by itself whether it is sitting horizontal or on its side for vertical.

It works stood on its side

Lay it on its stands and it detects vertical: Y self-levels plumb, the arrows walk the line left and right, and Line Scan centres it for you.

The casting shows you which way each axis runs

Slope indication marks moulded into the housing show positive Y and positive X, so you can line the laser up with your fall before you touch a button.

Two Things Worth Knowing.

Power: rechargeable, with an alkaline backup

The B10 NiMH pack runs typically 45 hours and charges in under 10 hours on the CH10, and it can charge while the laser runs. As a backup it takes 4 D-cell alkalines (not included), so a missed charge does not end your day. Never take the cells out of the rechargeable cage to fit alkalines: Spectra warns that charging will then damage the unit.

Check it before the job, and after any drop

The GL1425C carries a 5-year warranty on materials and workmanship, but calibration is the user’s responsibility. The 100 ft wall check takes ten minutes; it is step by step in the user guide under Downloads.

BLUETOOTH CONTROL

Your Phone Is Already a Remote.

The GL1425C has Bluetooth built in and a free-to-download app, the Spectra Precision Laser Remote. Spectra’s datasheet says the remote control or the app allows operation of all laser functions from anywhere on the jobsite.

Connect the app (user guide)

1. Turn the laser on. It is discoverable for the first 30 seconds (or start it from M › Settings › Pairing › Bluetooth).
2. Open the app, accept the license and turn on the phone’s location.
3. The level LED turns blue when the phone is connected.

Three ways to run it.

No phone, no remote

At the Laser Itself

✓Power on — always starts in automatic self-leveling
✓Grade entry on both axes
✓GradeMatch, PlaneLok, mask mode and every setting from the menu

The app or the RC1402

From Anywhere on Site

✓Grade changes without walking back to the tripod
✓Rotation speed — 300 / 600 / 900 rpm
✓Errors shown in plain text in the app

Why crews keep the RC1402

The RC1402 Remote

✓Radio range published: up to 330 ft
✓Works when the phone is flat, gloved-up or in the truck
✓Same buttons as the laser keypad

QUESTIONS & ANSWERS

GL1425C-28 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.

Before You Buy 10

What comes in the GL1425C-28 package?

The package includes: GL1425C Dual Grade Laser Transmitter; CR700 Machine Mount or Rod Mount Receiver; LARGE 5-inch Reception Height; with C70 Rod Clamp and C71 Magnetic Machine Mount; 105516 Vertical Adapter for HL Receiver; RC1402N Remote Control; Smartphone Bluetooth Remote Control / Free App; Rechargeable Batteries; Charger 120412-00; Small Carrying Case; Deluxe Heavy-Duty Elevator Tripod; SitePRO 11-815-C 15-Foot Grade Rod with Measurements in INCHES; Multilanguage CD, Quick user guide and Safety Instructions; 5-Year Warranty.

What is the Spectra GL1425C?

A self-leveling dual grade laser that does three jobs: level, grade and vertical alignment, read with the CR700 receiver included in this package.

How accurate is it?

Leveling accuracy is ±1.5 mm at 30 m (1/16 in at 100 ft); grade accuracy is ±3.0 mm at 30 m (1/8 in at 100 ft), per the Spectra GL1425C user guide.

How far does it work?

Up to 2,600 ft working diameter, so one setup covers a large job site.

How much grade can it run?

Typically ±9% in each axis on a normal tripod setup, and up to ±15% when you pre-tilt the laser with a tripod leg or a tilting base.

Do I need the remote, or can I use my phone?

This package includes the RC1402 remote, which does everything the keypad does from up to 330 ft. The GL1425C also has Bluetooth built in, so the Spectra Precision Laser Remote app lets your smartphone control it.

How long does the battery last? What if I forget to charge it?

The rechargeable NiMH pack runs typically 45 hours and charges in under 10 hours with the CH10 charger. You can charge it while the laser is running, and it also takes 4 D-cell alkaline batteries as a backup (not included), so a missed charge does not end your day.

How tough is it?

IP66 dust and water protected, and built to survive drops of up to 3 ft onto concrete and tripod tip-overs up to 5 ft. Check accuracy after any drop.

What is the warranty?

5 years on the GL1425C laser for materials and workmanship (calibration is not covered), 2 years on the RC1402 remote.

Where can I buy it?

Contractors-Tools.com is an authorized Spectra Precision dealer. Call 1-877-866-5721.

Using Your GL1425C 8

Can the CR700 go on the machine?

Yes. This package includes the C71 magnetic mount, so the CR700 goes on the machine as well as on the grade rod with the C70 clamp.

Can it measure the slope of existing ground?

Yes. GradeMatch measures the grade between two points with the CR700 in this kit, typically up to 260 ft, so you do not have to calculate it.

What does PlaneLok do?

PlaneLok locks the beam onto a receiver at a fixed point by radio, so vibration and temperature changes do not move your grade. It works horizontally on the Y axis and vertically on either axis, typically up to 260 ft.

How do I dial in a grade?

Press M, choose Grade, press E, set each digit with the arrow buttons and press E again. You can also hold an arrow key to step the grade up or down, or set it from the RC1402 remote or the Laser Remote app.

What happens if someone bumps the tripod?

The height-of-instrument alert stops rotation, turns the beam off and warns you if the laser is knocked out of position, so you do not keep working off a bad setup.

Can I use it vertically?

Yes. Lay it on its stands and it detects vertical. Line Scan centres the beam and the arrow buttons move the line, for anchor bolts, forms and layout.

Can I keep the beam off windows or other crews?

Yes. Mask mode blanks up to three of the four quadrants.

How do I check calibration?

Set up 100 ft from a wall at 0.00%, mark the beam on +Y and -Y; if the marks differ by more than 1/8 in, it needs calibrating. Repeat for the X axis. The full procedure is in the user guide under Downloads.

Troubleshooting 5

The screen shows Error 120. What happened?

The HI alert tripped: the laser’s height changed, usually a bumped tripod or a sinking leg. Press E to clear it, then re-check your elevation against your benchmark before you keep working (Spectra GL1425C user guide).

Error 130 during GradeMatch or PlaneLok?

The laser hit its mechanical limit: the existing grade is beyond ±15%, or the laser needs pre-tilting toward the slope. Clear it, tilt the laser with one tripod leg and try again.

Error 150 or 152: no receiver?

The laser cannot find the HL760 or CR700. Check that the receiver is on, paired, has not auto-shut-off, and is within radio range and on the right axis. Then restart the function.

Error 155?

More than one paired receiver is switched on. During GradeMatch or PlaneLok only one paired receiver may be on; turn the other one off.

The laser beeps and will not start rotating.

It is outside its ±5° self-leveling range: the level and manual LEDs flash together with a warning sound. Re-set the tripod closer to level. If it stays out of range for more than 10 minutes it shuts itself off.

STEP BY STEP

How to Set a Grade on the GL1425C.

The one job everybody asks about, the way we would walk you through it on the phone. The example sets 1.00% on the Y axis for drainage; the method is the same for any grade and for the X axis.

Before you start

The laser on a tripod, a grade rod, the CR700, and the laser, the RC1402 or your phone. Note which way your fall runs.

Set the laser up on the tripod

Solid ground, legs pushed in. Everything after this inherits whatever you do here.

Point the Y axis down the fall

The slope indication marks on the housing show positive Y and positive X. Aim with the sighting guides.

Switch it on and let it finish leveling

It always starts in automatic self-leveling. Wait for the green level light before you enter anything.

Open the grade screen

Press M, choose Grade, press E. The cursor starts on the +Y sign.

Type 1.00 for Y

Left and right move the cursor; up and down change each digit (and the sign, for a negative grade). Tap Manual to jump to X if you need a cross-slope too.

Press E

The “A” symbols flash while the laser levels to your grade. When they stop, the grade is set and the HI alert arms after its delay.

Check it on the rod

Read the receiver at a known point down the fall before you trust it with concrete.

Two things that catch people out

1. Past about 9% it needs a tilt. The laser beeps and shows which way: raise or lower one tripod leg toward the slope (or use the M401 tilting base) to reach ±15%.

2. It remembers yesterday’s grade. By default it starts on the last saved grade. Check the display before you trust it, or set Settings › Start Grade › 0 Grade on a shared laser.

The other job: matching a grade that already exists.

GradeMatch — five steps

1. Set the laser up over the first point and aim the Y axis at the second.
2. Put the rod beside the laser and slide the receiver to on-grade.
3. Carry the rod to the second point, receiver facing the laser.
4. On the laser: M › GradeMatch › E › E. “GM” flashes while it searches.
5. When it beeps, the measured grade is on the display and the laser holds it.

The one that ruins it

Do not change the receiver height on the rod between point 1 and point 2. The whole method works because the receiver is at the same height at both points.

Not sure on any of it? Call 1-877-866-5721 and we will walk you through it with the laser in front of you.
