    Comments about 330 ft. (100m) Laser Distance Measurer:

    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.

    • 330 ft. (100m) Laser Distance Measurer


      Will this display measurements in feet and inches ? I want to read on the display for example 12' -6-1/4''. I don't want to have to convert decimals in the field from a feet and inches in decimal format like 12.625'
