The first one I posted is out, the 4 vertical lines dont do what I want
I'm going to try a cheap cross line one, if it works all good but I'm not sure it will do what I want
I've got a big boiler install coming up and well any excuse for a new toy especially one with lasers
The multi beam and cross beam is what I need, dont have Leica money and it only needs to be spirit level accurate
