I’m tempted to purchase either a Bosch, or maybe Klein, Laser Distance Measuring tool.

They claim 1/16” accuracy, which to us woodworkers may as well be the Grand Canyon… We bicker (Or I do) over 0.005” of an inch… I’ve return Table Saws that have 0.010” deflection in the blade ;-)

How could I ever trust this thing???

Anyone using them with success…

I used one for many years to measure dimensions of houses. They’re fine for that purpose. They are extremely accurate but to that end, if you aren’t pointing it dead straight, you aren’t using it correctly and will get a bad measurement.

Not knowing what specific model you are looking at, I can’t speak to “how to use it correctly”. Mine was a device I’d hold against the wall, point across the room and click. It would tell me the distance to that opposite wall. But if i was pointing it slightly up or to the left, etc then I’m not measuring straight across the room so my results might be an inch longer than the actual dimension of the room +/-.

Honestly part of me was wondering how useful it would be for instance, in setting against your rip fence and hitting a carbide tooth on the blade.. that would be another layer of checking when setting up your crosshair/bubble… or even checking deflection?? Probably not that good right??
Again I was thinking more about shorter measurements like <5>

That is kind of ingenious, Fin. I would be curious as well. But I doubt it would work as we tend to deal with the thousandth of inches rather than 1/16” off here or there.

I got one as a gift once. I used it to rough measure rooms before going to buy baseboard and crown moldings,a nd I would add on a couple inches. I guess so I felt like a I had a use for it. I once heard the definition of “laser” as: “A high tech solution to a problem you don’t have.” that’s kind of what this gift was to me.

Thanks… I’ll be sure to update you with my results because I went ahead and ordered a fairly high end, color display, unit through Bosch today… ehhh if nothing else I got a great deal on it ;-)

Another thing about the 1/16th inch accuracy is that it is typically stated as 1/16th over X feet. With laser measuring devices X= a lot of feet. On mine it’s 1/16” on 200 feet. I’m not smart enough to do the math but being out 1/16 on 2,400 inches is pretty good
