Levling Question

Please define long-distance. How precise do you need to be? If it's for a railroad, not super-critical,, but if you are trying to level a high-speed rocket sled test bed, real critical.

Quality of instrument and operator would play a major factor, but I'd generally choose laser.

What do you mean by long distance?

Between those two choices, obviously laser.

Hello Guest,

All distance is Relative, you need to be specific.

The only Lazer I know spends most of the day on a couch watching TV.

When measuring long distances (intergalactic measurements) I have found that all optical measure is inaccurate, because the gravitational fields curve the light.

As far as levelling long distance, I have never had the pleasure.

Please reply, with

Kind Regards....

Water. You will need a bucket to carry it from one end of the long distance to the other. When comparing the two, make sure the water has stopped sloshing about. I do this in my garden all the time, and sometimes also use a plastic tube.
