Hi Paul,
Thatâs exactly what I used it for, locating steel and pipes and getting elevations of same. I happen to be back at the company that had the Hilti. I checked and they still have it, itâs still very popular with the pipe and structural designers. Matter of fact, I am taking it on a field trip next week.
The least expensive one that I have run across seems to be a quality instrument that I have come across is the one called the Disto Lite for $379. It has a range, or so they claim, of 650â with an accuracy of ±0.1â. Range is more than we would use, but what the heck. They offer a 30 day trail and payment plans J
I have seen cheap units that say laser tape or words to that effect, but they only use the laser to target. The measurement is done with sound waves. You can imagine how confused that instrument can get when attempting to identify one from a bank of pipes.
They really are great; you can locate a column or pipe in areas that are not safe to be physically close enough to work with the tape measure. Maybe pipingdesign.com could work up a large quantity price J

Some of these laser measuring devices are very expensive (thousands of dollars) but they are designed for really long (pipeline-type) range.
I was referring to ranges of less than, say, 100 feet for just doing existing column locations and that type of spotting.
This would be for smaller mod jobs where the existing plant drawings cannot always be trusted.

They are styled like some safety glasses, but I don't think they are approved
for use as safety galsses. They allow the wearer to see the little red dot
better in a facility's better lighter areas.

>>For what its worth. a company I used to work had a handheld Laser measuring
device for us our doing field work. It was made, or ay least sold by, the Hilti
company. It was very versatile and accurate. This was three years ago and I
believe the price then was about $650. They have come down, but not enough for
me to afford a good one for personal use. I would love to have one. The only
problems I remember when using it was, even wearing the laser enhancing glasses,
it was sometimes difficult to find the little red dot when using outdoors or a
brightly lighted facility. Also, if you set it on a surface that may be
vibrating from machiney running even little bit, it would be difficut to aim the
red dot where you wanted it. Anyway, I found it to be a very useful instrument.
Evidently others found it useful also, you had to reserve it days in advance in
order to get it. With it, I was able to get measurements affecting my design
