High-quality, inexpensive and very compact CIGMAN CM-701 3D laser level with three 360-degree green planes. The device also has a full plumb line, which is formed on the intersection of the two vertical planes above and below.
The main advantage of this model is its size, and the ability to adjust the brightness of laser lines in 4 options. The CIGMAN CM-701 laser level also has remote control, but see the review for details.
Oh, and also, the device has passed a large number of different certifications: CE, UKCA, RoHS, FC, FDA.

The build quality of the case is perfect, with all major parts having an almost imperceptible mating. And all other parts of the case also fit together perfectly.
Almost the entire surface of the case is covered with quality rubber.
The protective towers are made of plastic, and are fastened to four bolts through rubber gaskets at the top and bottom of the glass, which provides protection against the penetration of dust and moisture inside the case.
The instrument is equipped with good laser modules with factory markings. In the review below we will see the thickness of the laser lines at different distances.
The CIGMAN CM-701 laser level uses a built-in 3.7V 4,000mAh lithium-ion battery.
You can charge the battery while it’s plugged in through the USB Type-C port, which is also convenient. The port is located at the top of the back of the case under the rubber cover.
Due to the fact that the battery is built-in here, and the two main parts of the case are attached to each other using a slot-and-slot system, the case turns out almost monolithic. And in my opinion, the protection against dust and moisture should be much higher than the declared IP54.
In the base of the device neatly built in a brass bushing with a 1/4″ thread for mounting on a tripod, magnetic mount or swivel base, the latter two incidentally come with the kit.
The CIGMAN CM-701 laser level compensator
The laser level is equipped with a fast compensator of mechanical type on magnetic dampers.
It is installed inside on metal supports, which is undoubtedly a plus.
The speed of resetting the pendulum takes literally a couple of seconds, it is very fast.
The maximum permissible inclination of the instrument housing at which the compensator can align the pendulum is 4°±1°. If the inclination is higher than this range, the laser lines will automatically start flashing. This is a kind of visual alarm that indicates that the instrument should be placed on a flatter surface.
The CIGMAN CM 701 is controlled by a two-position toggle switch and four buttons on the top membrane keypad.
When the toggle switch is in the “open lock” position, all planes light up. Then you can use buttons V1, V2, H to switch planes individually.
But here there is a small disadvantage – the buttons can not turn off all the planes, will still light up some plane when the last one is turned off.
There is also a red power button on the control panel. It is responsible for activating the TILT function for marking oblique lines. To do this, turn the toggle switch to the “closed lock” position and press the red button for 2-3 seconds. Then all planes will light up, but the pendulum will be locked, allowing you to mark at any desired inclination.
Oh, and one more thing about locking. Be sure to lock the compensator when transporting it!
Also this red power button controls the brightness of the laser lines. When you have the CIGMAN CM-701 laser level on, the brightness will change with each brief press of this button. A total of 4 brightness modes are provided. See below for a Luxmeter measurement of the brightest mode.
Here you can see 5 indicators on the panel. Four indicators show the gradual discharge of the battery. Another indicator at the top is green when the instrument is on and ready for operation, and red when the TILT mode is on or the instrument body is tilted above the compensator operating range of 4°±1°.
Remote control of the CIGMAN CM-701 laser level
All control is duplicated on the remote control. With buttons V1 and V2 the verticals are switched, with button “H” the horizon is switched off, and with the fourth button the brightness of the laser lines is adjusted. The TILT function cannot be switched on with the remote control.
I must say that the remote control is also well made, has a good, balanced on the elasticity of pressing buttons, with a duplicating indicator in the corner, which lights up a nice blue color when pressed.
Laser line thickness at different distances
In this test, the CIGMAN CM-701 laser level performed well.
At 1 meter from the wall, the line thickness is just over 1 mm, at 5 meters it is about 1 mm, and at 10 meters it is 2-2.5 millimeters thick.
Measuring laser line brightness
The brightness will be measured in the brightest mode. For those who don’t know, laser levels with cone prisms have non-uniform brightness around the perimeter, there are dimmer areas and brighter areas. Therefore, I measure at different distances and different areas.
And so, the results are as follows:
- 5 meters bright side – 26.6 LUX
- 5 m faint side – 4,4 LUX
- 10 m bright side – 10.3 LUX
- 10 meters dim side 1.8 LUX
See the complete brightness table for many other models of laser levels.
Declared accuracy (compliance)
Testing at 10 m showed that the CIGMAN CM-701 laser level fully complies with the stated accuracy specifications of ±3 mm at 10 m.
At this accuracy, the maximum distance between points at 10 m can be 6 mm. (See how the accuracy is calculated correctly for laser levels with cone prisms)
No serious deviations were found in the verticals.
Adjusting the CIGMAN CM-701 laser level
If necessary, you can calibrate the device yourself, here it is quite simple.
1) After checking it turned out that all planes have the same deviation.
In this case, it is necessary to correct the position of the pendulum as a whole.
a) If the horizontal plane is facing up or down, the longitudinal alignment bolt on the pendulum must be screwed in or unscrewed.
b) If the horizon is tilted to the right or left, you must use the cross alignment bolts on the pendulum. There are several of them, 4 on one side and one on the other side. If the misalignment is small to 2 mm, moving one bolt will be enough.
2) Two planes are exact, and the third has a deviation
Here you directly adjust the position of the individual laser module. The calibration is done with the four screws at the base of the module.
