It works! The 'Poor Man's Laser Level' proves itself to be accurate!

This is a video of a trench that was laid out with the 'Poor Man's Laser Level' and dug out to an average depth of half a shovel blade (soil was rocky in places). I was pleasantly surprised that I had a continuous puddle of water that stretched at least 300 feet! The water drained into arroyo as hoped and fed into a couple of check dams in the arroyo to hold back water for percolation. The soil should be saturated behind the dams now and can be made ready for planting of winter wheat and fall rye. Update: The total length of the trench is about 490 feet (197 paces at about 2.5 feet per pace).
