New, unique in its kind 4D laser level Huepar S04CG with optical scheme 2H/2V/plummet.
Today, you will not be surprised by two horizontal planes of 360 degrees. Such models already exist, the same Huepar 904DG or, for example, Fukuda MW-94D-4GX. But only the Huepar S04CG laser level has a screen that displays the angle of inclination of the housing. Yes, by the way, electronic inclinometers can be independently calibrated.
There are some other advantages, for example, the presence of Bluetooth, but about everything in order. Looking ahead, I can only say that the device is definitely worthy.

The build quality of the housing
The case is made of high-quality composite plastic, which is almost completely covered with a two-millimeter layer of rubber. The rubber is very dense, so it looks more like soft touch plastic.
The ergonomics of the housing is made in such a way that it is comfortable to hold in your hand. Despite the fact that the housing has a difficult form, it is made very high quality. The pairing of the two main parts is almost imperceptible.
On the side, under the rubber cover, there is a USB Type-C connector for charging the battery installed in the device. But you can also just work from the mains without the battery installed through the same connector.
This is undoubtedly a plus.
Thus, the maximum variability of power sources is realized in the Huepar S04CG laser level. From a lithium-ion battery, from AA batteries, and from the mains. You can also add a power bank here.
All the protective towers except the lower big “paw” are made of metal. They are attached to four bolts. But the most important thing is that all the towers are attached through rubber gaskets. Moreover, the glass is inserted into a special groove in the rubber gasket, which is on top, which is on the bottom.
Therefore, the penetration of dust and moisture into the interior of the housing through the towers tends to zero.
As for the large lower protective tower in the form of a “paw”, it is made of plastic. And this is not the best solution. In general, not bad, but it feels like you can easily break it if you fall. I could be wrong.
At the bottom of the “paw” there are four rubber supports. Therefore, the Huepar S04CG laser level stands confidently on slippery surfaces such as tiles or laminate.
There is also a 1/4-inch thread for mounting on tripods or other optional accessories included in the kit.
The battery cover is not removable, this should be attributed to the advantages. It opens by clicking on a black improvised button. Quite an interesting solution.
Yes, by the way, on the battery cover there are abbreviations of all passed certifications, and as you can see there are a lot of them.
But it should be noted that despite the fact that the inside of the lid is covered with a layer of rubber, it does not close very tightly.
It should also be noted that high-quality laser modules are installed in the laser level, which project bright and thin laser lines. This is a big plus.
LCD screen with backlight
This is the most important difference between the Huepar S04CG laser level and other similar devices. In general, laser levels with screens exist, but as a rule, they show only the remaining charge, and information about the enabled mode.
In Huepar S04CG, in addition to all the above information, the angle of inclination of the housing along the “X” axis and the “Y”axis is shown. These are completely different possibilities for solving highly specialized markup tasks.
The device has a classic tilt compensation system within 3.5°.
In this interval, the pendulum will be set strictly vertically. If the angle is exceeded, a visual and audible alarm will automatically start. In other words, the laser lines will flash once every half a second with a simultaneous audible alert.
This is done so that the user understands that the markup is currently being performed incorrectly.
In the mode of operation with a locked compensator for marking at any arbitrary angle, the lines also flash. But once every 5 seconds and without sound. This is also a kind of informational notification that a special mode is selected.
Installation of the compensator after switching on or pushing the device occurs within 5 seconds. This is a little more than declared.
Laser level control methods
The Huepar S04CG laser level has several control options, let’s look at all three ways.
Toggle switch and control panel on the device
On the side is a two-position toggle switch that locks the compensator for transport, and also turns the laser level on and off.
By the way, the pendulum is not locked quite tightly, so when shaking, you can hear a characteristic sound. This backlash is allowed, and is not considered critical.
When you turn on the toggle switch, all four planes immediately light up.
Further control is performed by the buttons on the top.
Here everything is simple. The “H” button is responsible for switching the horizontals separately, and the “V” button is responsible for switching the verticals. In this way, you can choose any combination of planes. This is very convenient.
The button in the middle is responsible for turning on the receiver mode and activating the TILT function. (hold the button for 3 seconds while the compensator is locked)
The Huepar S04CG laser level comes with a Bluetooth remote control.
To activate the remote control, turn on the laser level and hold down the white power button on the remote control for 5 seconds. The white button should change to green. If this button is red, the remote requires charging.
Buttons “F1” and “F2” are inactive here. According to the manufacturer, they are intended for other new models. What functions will be tied to them is still unknown.
Buttons “H” and “V” completely duplicate the buttons of the same name on the device.
The upper button is the brightness control, but, in fact, it just duplicates the lower button “P” – the mode of operation with the receiver. Thus, both of these buttons switch the Huepar S04CG laser level to a pulsing mode for working with the receiver, at which, as you know, the lines start to burn a little dimmer.
The Bluetooth remote control (model QBR07B) is equipped with a built-in 3.7 V/200mAh Li-ion battery and it is also charged via a USB Type-C connector, which is located on the side.
When the device and the remote control are turned on, a short press on the white power button on the remote control will simultaneously turn off or turn on all planes.
Controlling with an app on your phone
First, you need to download and install a special app called “Huepar” in the Play Market on Android or the App Store on iOS.
Then open the app and turn on the device. If everything is fine, then you get to the first screen, where you need to click the line “S-serials” (photo below)
Then the application menu will open. There is nothing special here. “Information” and “new products” there are simply listed models, so we will not focus on these buttons. “Settings” – in this menu you can change only the language. We are only interested in the button “S series”
Click it and get to the main control panel of the laser level Huepar S04CG
In fact, this is a complete duplication of the display on the device. Here you can select the necessary combination of planes, see which planes are activated, and see the angle of inclination along the “X” and “Y” axes.
You can also activate the receiver mode.
The mode of operation with a locked compensator (TILT) can not be turned on either from the remote control or from the phone.
Another such moment. In the upper left corner there is a power button, if you shortly press it, you can immediately turn on or off all the planes.
Huepar S04CG laser level functionality
Today, this is probably the most functional laser level that has no analogues. It’s only a matter of time, but it’s still a top model.
Two horizontal planes of 360 degrees allow you to work as comfortably as possible, both with ceilings and with floors to choose from. It is also possible to project the verticals as close as possible to the walls.
Marking on the street in sunny weather is also not a problem! A special mode of operation in conjunction with the receiver allows you to work on the street at a distance of 80 meters in diameter.
The TILT function will help you cope with non-standard design tasks where you need to mark up inclined lines.
The LCD display, TILT function and built-in inclinometers will help you set a certain slope of any construction.
Also in this mode, the device will automatically turn off after 5 minutes of inactivity. And every 30 seconds, an audible alert will be heard in the form of a short signal.
In general, the laser level Huepar S04CG = maximum functionality!
Checking for accuracy
The declared accuracy of this model is ± 2mm/10m (±1/13 in at 33 ft). Therefore, the maximum allowable run-up between points at the horizons at a distance of 10 meters should not exceed 4 millimeters. You can see how the error is correctly calculated here.
The photo shows that the upper and lower horizon, when checked by sectors at 10 meters, absolutely exactly fit into the declared corridor.
All vertical planes were checked by a thread plumb line. No deviations were detected.
But do not forget that any laser level may need to adjust the accuracy over time. How this is done will be discussed below.
How to do calibrate at the laser level Huepar S04CG
Almost all 4D laser levels with two 360° horizontal planes have the same adjustment algorithm.
- the lower horizon is usually adjusted by the position of the pendulum,
- adjust all the remaining planes individually.
Setting the position of the pendulum is done with two bolts: longitudinal and transverse. The longitudinal adjustment bolt can be reached by removing the protective tower from the front vertical.
To get to the transverse adjustment screw, you will have to unscrew the device housing. It is located above the toggle switch.
The upper part of the housing is not removed freely! Everything is very tight inside. But there is no need for a full disassembly. The upper part opens so much that you can easily adjust the position of the transverse adjustment bolt.
There is nothing difficult here. By moving these bolts in the body of the pendulum, its center of gravity changes, and when it is switched on again, it is set differently. For more information, see the video at the end of the review.
After adjusting the lower plane with these bolts, we check the accuracy of the remaining planes. And if necessary, we adjust them separately. The adjustment is made by four bolts at each laser module.
Calibration of tilt sensors
The Huepar S04CG and S03CG laser level models provide calibration of the built-in inclinometers. Therefore, if your tilt sensors display incorrect values on the screen, do not rush to despair, it is very easy to fix.
The calibration algorithm is as follows:
- install the device on the most flat horizontal surface
- turn on the laser level with the compensator locked
- hold down the “V” button for 5 seconds. The values on the “X” and “Y” axes will be set to zero. That’s it, the sensors are calibrated.
The thickness of the laser line at different distances
This test showed the following results.
At a short distance of 1 meter, the line thickness was just over 1 millimeter.
At 5 meters from the wall – 1mm!
And at a distance of 10 meters, the lines became a little more than 2 mm! Excellent results! The brightness at all distances is perfect!
The lines always look thicker in the photo. The true thickness cannot be captured due to the high brightness.
