The patent application process is a rigorous process that ensures that one manufacturer does not completely replicate another manufacturer on one idea or invention.
Because of this, there are many types of devices and programs that use laser leveling.
I will cover several more common types and how and where they are used.
What one needs to know first is some security issues.
Don't look directly with a laser, and don't shine someone else's eyes with a laser.
These tools can cause serious damage to the retina of the eye and sometimes even lead to blindness.
Ensure the line of sight from the area where the laser leveling machine is located to the work area (s)
Obviously, you don't want to inadvertently block a line projected on the surface.
Nowadays, there are two types that dominate the market, one is mounted with a tripod, which is more expensive, but it cannot be defeated in terms of accuracy.
Larger lasers like this are also useful in larger areas or outside.
The tripod can also be height adjusted through the telescope, which is good when installing the ceiling.
The handheld model is more affordable, but the accuracy has declined, and the distance of the laser to "draw" a line is greatly reduced.
In most cases, the handheld model is enough for the average homeowner ,(
Unless you are building a home)
Or casual users.
I suggest setting a level automatically.
There are a lot of this feature, and the cost difference is not enough to worry about.
Use a laser mounted on a tripod to remove areas that work in obstacles and anything that may interfere with a beam or tripod.
Set up a tripod, if the surface is mounted and the legs are adjusted, make sure it is plum blossom by hanging a pendulum from the center, so that the pendulum hangs at the exact center of the leg.
Most of the tripod has a lower platform with an indicator point or cross on it.
This step can be omitted if the laser leveling machine is automatically adjusted.
Then install the laser on the tripod and open it.
The rest depends on you.
Handheld laser is much easier. In fact, most lasers are self-flat, you just need a clear surface to set the level without obstacles, place the level on the surface, open it, aim at it, then go to it!
That's why I prefer this unit for ease of use.
There are other types, the use is getting less and more complicated, please consider carefully before purchasing the laser leveling machine.
