Cons: i've used these everywhere, haven't found 1 negative aspect of anything these guys make. This Laser, when paired with the Berger CST tripod is formidable setup for layout. Probably the best all around laser out there. i used the RoboTools self adjusting laser when it came out, the remote was cool but the price wasn't. When Berger put these on the market i was happy to get one. As with any laser, they are very delicate instruments. Don't be dumb and drop these out of carelessness. Its the most important aspect of building anything, treat it properly.
CST Berger 5 point laser
Rain proof. Accurate, bright, small dot. So many applications for this thing. Lets see if Bosch ruins their name, their lasers don't last long on commercial job sites, but these CST's do.
