    Quality laser with good features
    When you spend this much money for a tool, you do your research to make sure it is exactly what you want, right? Well, that's what I did, and it looks like this laser lives up to my expectations.

    It is obvious that it is quite sturdy and well made; I am not nervous about my tripod being kicked over by an oblivious employee. The unit powers up and performs exactly like you'd expect, with very precise grade changes. The receiver is one of the best features, with a 5" window, green light and beeper to show when you are dead on. The remote is a nice addition, but I have not yet had an occasion to change grade on the fly without moving the laser itself.

    The only drawback I can come up with is that the controls are not terribly user-friendly. I need to keep the manual handy in order to walk myself through the steps of setting up grade, or using the mask feature. A more thorough, user friendly manual could have helped with this product.
