I thought laser levels were a gimmick until I used one on a retaining wall
For like 10 years I was a string level guy all the way. Thought lasers were for guys who couldn't read a bubble. Then I took a job building a 60 foot retaining wall in Tacoma last fall and the ground was way too uneven to pull a tight string. Borrowed a Bosch GLL from my buddy and honestly it saved me like 3 hours of rework on the first course alone. The thing kept every block dead level across the whole run without me having to climb up and down 50 times. Now I feel kinda dumb for being stubborn about it so long. Has anyone else switched over from old school methods and felt dumb for waiting?
...and that's exactly what happened to my neighbor Stan up in Bellingham. He spent 30 years doing concrete work with nothing but a string and a 4-foot level. Last summer he had to pour a sidewalk that curved around a big oak tree and he was out there for two days trying to get the grade right with his old methods. His son finally bought him a DeWalt laser level for his birthday and Stan called me that night almost mad about how easy it was. He said he felt like he'd been carving wood with a pocket knife when chainsaws existed the whole time.
Wait, am I the only one who thinks there's something to be said for the old way though? I get that the laser level made the job way faster, but Stan spent 30 years reading a site with his hands and eyes, and that kind of skill is hard to replace. There's something to knowing the ground by feel that you just can't get from a gadget, you know? And what happens when the battery dies on that DeWalt mid-pour and the sun's going down, and there's no backup? The old methods might be slower, but they'll never leave you stranded.
