Frequently Asked Questions (FAQs)
1. What is a laser line detector used for?
A laser detector can find the position of a laser beam in relation to the measurements of a grade rod, which can ensure a more accurate reading by providing an audible sound when the device has found the laser.
2. Will laser detector work with line laser?
Different kinds of laser levels will only work with specific types of laser detectors. For example, rotary lasers will not work with line laser receivers. Also, because red and green lasers operate at different frequencies, they require laser receivers that are tuned to their specific frequency.
3. How accurate are line lasers?
Good laser levels are accurate withing 1/16 of an inch per 100 feet. This is ten times more accurate than a spirit level, which is only 1/2 inch per 100 feet. This level of precision is made possible through a laser diode that emits a concentrated beam across the area you need to level.
4. What is a 3 line laser level?
This 3 Line Green Laser Level features a green beam for clear visibility on the jobsite. This laser features a second plumb line that forms a 90-degree intersecting line on the floor and ceiling, great for installing lighting or cabinetry.
