#AtoZChallenge L is for Laser Transit Accuracy

The key to an effective and affordable drainage solution is to create a negative grade or pitch so water will naturally drain away from your home. We achieve this with great accuracy by employing a laser transit for accuracy.

A laser transit is a tool which offers solid-line laser mounted in a set location. The laser used by these devices is visible in the air, which makes for easy tracking. These devices are used in surveying and construction to create an easily-identifiable, but non-permanent, line. The laser transit was first used as a surveying tool—it was mounted onto a standard survey scope to provide a visual indication of the scope’s tracked line. This tool has since branched into other applications, such as construction and home repair, where it is commonly called a laser-line level.

Transits are common in many fields of science and engineering. Each of these devices has specific functions, but they all have one thing in common. Transits allow measurement or observation of very specific slices or areas of space.
