When you are trying to make line alignment at quite longer work distance, such as out of hand reaching or outside place etc, it is not any longer use of manual line drawing, but would have to choose even more advanced laser diode tech applied blue line laser module. it is a very easy work for users to operate such kind of laser line generator, only according to its proper equipment of 4.2V DC input power supply, it is just able to get continuous blue laser line emission all the time.

The use of Berlinlasers blue line laser module makes the best use of metal heat sink cooling system and APC driving circuit, within 8 hours to 10 hours continuous line alignment work, it is just keeping highly stable blue line targeting on desired working surface all the time. The operation of this laser line alignment tool has no serious limitation of work distance, height and other occasion, but noncontact blue line takes the lowest time consumption, making sure of the clearest line instruction all the time.
