great tool
I ordered this to find operating distances for moble cranes it works great so far very accurate. The only problem i have is with the spotting laser i have a hard time following it past 75 ft this thing would be awesome if the laser was a little brighter.

HUGE Time Saver!!
I'm in the market for a new house and I need to make sure that all my existing furniture and other junk will fit into a new place. I was using my tape measurer but I got a little sick of the reeling and unreeling. I was at an open house and I saw someone using a digigal measuring device and I realized it was the way to go! Here are some of the reasons that I now find this a "must" for house hunting:

1. The red laser dot lets you clearly see where you are measuring to.
2. It stores you previous measurements so you can check out a place and go back later and get all the square footages from your saved location.
3. The unit is small and fits in my pocket.
4. It automatically and easily calculates square footages as well as cubic feet for spaces.
5. I can go around a house and have the place mapped out in about 10 minutes.
6. It can be used as a level to get a sense of how true the floors are.

Beyond the thing I use this for, I see there are tons of other ways to use the unit. I love this product and would highly recommend it to anyone who needs to take fast and accurate measurements.

does this convert inches to meters?
ROCKIE on May 27, 2016
BEST ANSWER: I can't answer that right now, as I don't normally have a need to do so. I will certainly check for you when I get to my vehicle early this afternoon and let you know.
Can you see the light outside in bright sunlight?
Me on Jul 15, 2015
BEST ANSWER: Yes, the large 3-line backlit display helps improve screen visibility in both dim and bright conditions.
Does this have lazer pointer to show were the measutement is coming from. I have one now but don't trust it because sometimes I get false reading that comes from something in room.
CJB on Feb 6, 2016
BEST ANSWER: Yes, the distance measure has an indicator so you know exactly where it is targeting
