How far can laser level dots be seen outside in the sun?
The laser beam itself will barely be dissipated by the sunlight, check the specs on each device for their range. The difficulty seeing the laser can be attributed to the sunlight flooding all* light spectra/frequencies as well as sensitizing your eyes (or camera white balance) to light. Creating a shadow with your hand near the laser point on the wall should easily reveal it. If you can find/afford it, a green laser would work better for outdoor applications, the light frequency is further away from infrared as well as they are typically stronger.

* "All" is relative to visible frequencies (and a few invisible ones) but for cases of visible light by human eyes, the near red frequencies are visibly flooded heavier due to infrared being so close.
