For longer range work, I find a basic laser level very useful - I have a
cheap Stanley cross-line laser from ebay for 90 quid (double that if new).

The downside is that you cannot see the red line outside - though you could
set up and mark up in the evening.


You couldn't trust the projected horizontal or vertical lines at a distance
because the lenses have some spherical aberration which causes the lines to
curve. It is much more accurate to use the spot beam to transfer some
reference marks onto your distant target and then continue the local
marking-out with your good bubble level. With a short, cheap laser level
you'd definitely need to turn the level around and do some averaging, but the
spot beam is much brighter than the lines and can be used in bright sunlight.

I paid £19.99 for mine, with not much in the way of expectations of its
accuracy from me - but I just cannot fault it even over 30 feet, when
compared to a water level or Stabila. It came with a tripod, you fix
the head on the trip release the internal bob weight, then turn on the
H V or both beams. You don't need to set it up, so long as the tripod
is roughly level it will do. I used it to build a small extension, with
string lines between for getting the courses straight, tiling and a few
other tasks over the years - much easier than a level.
