Title: U NEED THIS
Review: This is very well worth every cent I spent. Just think of all the money you will spend on building materials not to have them level. Just sorry I had not had this years ago. Speeds up your leveling process with more accuracy. Works great for a 1 man operation. Works great in the brightest sunlight. Audio signal is teriffic. Even dropped it a couple of times and still works great. all lasers should come with one.
