What is a disadvantage of using laser alignment systems?

The reason that frequent recalibration is considered a disadvantage of laser alignment systems is that these systems rely heavily on precise measurements to ensure accuracy in the alignment process. Over time and with changes in temperature, vibrations, or even mechanical movement, the calibration of a laser alignment system can drift. This necessitates regular recalibration to maintain precision and achieve reliable results, which can be time-consuming and may hinder efficiency on the job.

In contrast, traditional alignment methods, such as those using dial indicators or straight edges, might not require as frequent recalibration and can sometimes provide a more straightforward approach in certain environments. While laser systems offer enhanced accuracy and ease of use in many scenarios, the need for ongoing calibration remains a notable consideration, particularly in dynamic settings.
