My brother brought out his laser level so we could dig some level areas and to scope out some pond stuff. Seemed like a pretty smart device. You get the little bubble exactly in the circle and then wander around with a beeper-thing-on-a-stick. Every place is perfectly level. And then it rained. And it turned out things were not perfectly level as water typically runs downhill. I suppose gravity might work different here, but I really think this laser level thing is stupid. So my brother says that sometimes they get whacked and they are no longer level. He then suggests I rent one. But I can't help but think that a rental unit may have been whacked. And couldn't the same be said for one that was new at the store? And mail order cannot be trusted either. I think the idea of the laser level is great. To make sure that two points that may be 500 feet apart are level. Is there such a thing?
