Water level cheap easy accurate and you can see it in daylight.60 ft 5 bucks at the box stores.That's what I ended up using after I could not see my fancy laser.If you decide to go with a laser go high end or you won't be able to see it.
Im sure that you can't see the laser at 50ft with about every laser during the day light.
Has anyone ever tried using a laser at dusk and were they able to see the laser well??
One of my buddies said he just used his laser level at night and didn't have problem with seeing the laser and marked all his boards and started the next morning on building again
