I first used a rotary laser in 1986-87ish. On my first big commercial job. Wow! What a game changer. I your work requires a lot of elevations checks, these are a MUST-HAVE tool! One man can set grade stakes all day long much faster than a two man team with an optical level and and a grade stick. Can't remember exactly but I think it was fast beep=go down, slow beep=go up, and solid tone=on grade. For concrete flat work? Forget about it. Dump a little pile of concrete at the opposite corner of an imaginary square a foot or so smaller than your screed length and strike it off to grade with the laser. Then connect the pile with a line of concrete back to the form. Use the floated pile and the form as reference to screed the connecting line down. Now you have a line on grade and a form on the other side. Fill in between the line and form and screed off the filled area. One 10 or 12 foot box at a time. 1 man on the hose, 1 or 2 on the screed, 1 checking grade, 1 with a come-along/rake. No grade stakes to pull/forget. No more screed pipes leaving low lines. Dot, connect, fill, dot, connect fill, dot connect fill. + - 1/8 in in 10 ft with ease. Lather, rinse, repeat. All day long. They really changed the game.
Last week I was on construction site where concrete crew was using some Bosch rotary laser. I was called to check concrete level. Worst spot was +2mm from projected level and it was 40x110m building.
Spent 700£ on 3plain laser Great level but there magnetic bracket is not strong enough i won't to put it on a metal stud with out it falling down at the first small bump bracket for the 3 plain is exactly the same as my bosch 2 plain but the laser is 3 times the weight.

ah bugger
Last week, Milwaukee announced new green line lasers to be available in November, but no rotary lasers. I'd bet they aren't far behind though.
good to hear!
As far as lasers go that’s a monster 😯
Yep true, but it does everything EXCEPT make you a coffee 👌🏻
