Laser distance measuring device Company: SNDWAY Distance: 100 meters Condition: New Measurement types: cm / m / m2 / m3 / inch / and more.... Excellent device, I've used one like it for over a year with no issues. The last time I used it was two weeks ago to measure a room for buying floor covering. I also got one for my father as a gift a year ago, and it's been working perfectly for him until now, by the grace of God. Excellent for measuring large areas without the hassle of traditional tape measures or needing someone to help hold it, especially on uneven ground. With this device, you can easily measure up to 100 meters in one second. It's also excellent for measuring heights that are difficult to measure with a regular tape measure. The device does not come with a warranty, but I guarantee it for the buyer for a week of operation after two days of shipping.
