What the difference bewteen this laser leveler and others?
The biggest difference is that our product has red/green/blue three laser colors, while others only have one green light which is more suitable working indoor, so our scope of application is wider than others.
Why this product doesnt have a turntable at the bottom like others?
We have designed a rotating chassis at the bottom of this laser level, which can meet the requirements of rotation without additional support. Therefore, we didnt provide a turntable because you acutally didnt need that.
What is the use of these 3 color laser lines? What is the use of laser lines with three colors?
No, we designed three color laser lines to make them more useful. The green line is not easy to be seen outdoor, while the red one can. And the laser lines of three colors indoor can help you better distinguish each plate and make the work easier.
How long can the battery work when fully charged?
A fully charged battery can work for about four hours. We have an extra battery given so if you need to work for a long time, please be sure to charge them in advance.
