for something that will project a level line over 50' and in all directions...you're gonna have to spend a few hundred bucks for something with the accuracy you need ..even if the B&D units were accu

or get a long piece clear plastic tubing and suspend it from a known point. fill it with water and walk around the area you want to level maeking the level points by the level of the water in the tub

It's a lot of bother, but its dead-on accurate: A hundred feet of clear tubing and some water. Phil "used to build lasers, too cheap to buy one" Ethier

I was wondering about this... Is the proper use of a water level described anywhere? I'm wondering how this works on sloping ground. Like, if you're doing a pole barn and the ground slopes 8" down o

I don't know how you're "officially" supposed to use one, but I've done this to level a huge deck and also the foundation for a 38' x 25' hangar, and they've come out as close to perfectly level as

Nope. Regardless of the location of the intervening tube, the end points will be level to a high degree of accuracy. Errors due to local gravitation gradients (including tides) will be microscopic.

I know the two end points will be level. What I wonder about is if the two end points will be at the same place they were on a previous measurement. I.e.... You've got a water level, with all its tu

The level stays the same as long as the ends don't move - the pressure difference isn't enough to compress the water or expand the tubing enough to be detectable. As I posted before, once you carry

Mark Andy Nope. The volume of water in the tubes is exactly the same, so the water level doesn't change on the ends. If you raise and lower the entire "system", including the ends, then things change

I can't think of any reason for the level to get lower on both ends unless the tubing expanded or got longer. Dave Russell

Yup - that's how you do it. The reservoir would be a great help if it's relatively large, but the volume in the reservoir relative to the volume of water in the tube will determine how sensitive it
