This is a Bosch Red, 800′ 360? Self leveling laser. It is as top of the line as you will ever get with this tool. This one is brand new. Never even been on a job site. Everything is still in the packaging and it still has the original batteries. I bought 2 and ended up only needing one. I own and operate a concrete and paving business and I can tell you that if you’re doing any grading or leveling of earth you need one of these.
