Choosing A Line Laser Level for Indoor Use Only

This article will help you determine if an indoor line laser level will fit your needs. Line Lasers project lines either vertical, horizontal or vertically and horizontally simultaneously.  All line laser levels are self-leveling and higher quality line laser levels will have a locking compensator, so the inner workings of the laser will not fall out of calibration during transport of if the laser level is dropped.  All Johnson line laser levels have locking compensator systems built-in.
