@Hedwig Well first there is the manufacturers own specs. You can get off their websites

Comparative study of accuracy in distance measurement using: Optical and digital levels

That PDF is the owners manual for the 600M one

Notice it says 100lux ?

Sokkia's LDT520, a 5” digital theodolite equipped with a telescope with laser beam emission capability, boasts the world’s longest laser range, class-topping dust and water protection,and a continuous operation time over 2.5 times that of its predecessor. The LDT520 is designed for directional controls in tunnel excavation, precise marking and alignment in construction and engineering applications.

It has to be dark to see the reflection

600m meters on a cvery dark day

Daylight washes it out

I doubt it is even very accurate at 600 meters

Which means @Hedwig

Next we have what is called Spatial Disorientation & Visual Illusions which includes our visible horizon. Sometimes called the offing, this apparent line is where the sky meets the ground and is being perceived as an edge because of perspective due geographical slant and other optical phenomena.

Lastly, do you believe we live on a cylinder? If you think the horizon drops, it should be dropping in a 360 degree circle around you. 3 boats spread apart by say 20 miles should be at different heights.

<@561690854620659723> it says angle

Take a look. All the information is there.

I dont believe you are a surveyor or you would know this

Yes it is

Its max distance

Which is measuring angle

Lol

Show me specs for a Theodolite that is capable of measuring anything beyond 600 meters

Thats not accurate.

You are using the Theodolite incorrectly. Plus i dont believe you.

Im talking about measuring anything with a theodolite. Its 600 meters max.

After 600 meters the accuracy is not correct

Look it up

Its accuracy of the entire theodolite

Show me specs of a theodolite operatiing furthing than 600 meters

No its not just the laser
