I've got this "straightline" laser level, the one that resembles a tape measure. Now the laserlight beam comes out of the tool about 1" higher than what you have it placed on. Here's the Question-Example. EX: If I set 1 starter FencePost and place the level on top of said post, when I sight-up the final post, say 100' away, should the bottom of the laserbeam be 1" above my final fencepost or does the laserbeam compensate itself for this? It projects a "line", one that is brighter on the upper part and fading away on the lower, not a bright "dot". I'm still using a stringline for measurements but a 100' string is tuff to check for level. There's no instruction sheet and I don't want a group of fence posts gradeing up as I go along. Thanks for the help.
