Hey, I'm someone who the laser transmitter only hobby used (ie not in daily use, but rather a twice a month for a few hours). I bought the glasses to the laser spot of my Disto better seen X310 laser measuring device during the day. And yes it works well. Unfortunately, the thing is not miraculous. That I see as point better, but a real benefit gain is the thing now synonymous not. Although this has probably nothing to do with the glasses themselves but I wanted to mention it here once. Ie up to about 15m you can see the point quite well outdoors (I'm talking about a bright and beautiful day with lots of sun), without glasses one has since been quite an effort to see the point. At about 22m but then I have not seen the point, despite a long search no point for me was erkennenbar. Since I have already worked with other laser measuring devices I would buy laser measuring devices with optical viewfinder. This (PD42 Hilti) I was also possible in open space, without walls, to make a person to about 90m. Ie using the optical viewfinder saves you my opinion, the laser measuring glasses. Measure the much professionals then use anyway completely different systems with electronic receiver (but that's a completely different price category).
