The red DeWalt you have purchased is accurate to .3mm over a meter, so over a room of 8m you could be out by 2.5mm
Pretty much similar to spirit levels.
I’m basing this on an average Bathroom (the only tiling I do) being about 8 linear metres on the horizontal plane and being about 1 to 3mm out if I draw a level line around the room.
Anyway, great advise on the Dewalt Gents. Looks like I might need to go shopping. Any places that sell it over the counter?
