I don't know about green £££ lasers, but with a red one not much chance
beyond about 3 metres in daylight, unless you like working at twilight
(or willing to buy a laser receiver, in which case make sure your laser
has a pulsed mode).

It happens that fred formulated :

A cheap red on will work outside, but at dusk.

I find red OK if you use a white target.

I have my grandfather's Cowley level, and I know how to use it

I've just checked my Bosch Quigo self levelling green laser device outdoors

With a white card as the "detector" I could just about see the line at
around 6 to 7 metres. Without the white card I could just about see the
line at 4 to 5 metres on my hand. This was at mid-day - bright overcast sky.

Do you mean outdoor as in waterproof, or outdoor as in seeing it in full
sunlight?

Slightly sideways.. have you considered a *water level*. As used by the
Egyptians:-)

Use requires a bit of care but they have benefits not available to
lazers. Firstly, you don't require line of sight. Secondly, they don't
need initial levelling.

I see Screwfix have a kit for £17. Don't leave water in the pipe for
years as mine grew fungus.

With the cap on the hand held end and *off* at the reference station,
you can move to your measure point, remove the cap and adjust the gauge
height to the level mark.

Tried a water level once for hinges on gate hanging. Useless as I hadn't spotted the bubble :-(

That's going to need a very powerful laser. With the associated H&S
problems.
