When to Use a Cross Line Laser vs a Rotary Laser
The bottom line is that rotary lasers are meant for outdoor applications where you need high accuracy and—most importantly—when you have a receiver/detector. A cross line laser uses less moving parts. A prism allows a nice, even beam that is extremely bright and easy to see. That goes double for the newer green lasers hitting the market from DeWalt, Bosch, and others. Can youuse a rotary laser indoors? Absolutely? Shoudl you? Probabaly not—assuming you can use a brighter line laser instead. For hanging cabinets or laying our flooring, a nice cross line laser can't be beat.
