Laser distance measuring device Company: SNDWAY Distance: 100 meters Condition: New Measurement types: cm / m / m2 / m3 / inch / and others.... An excellent device, I have 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 bought one as a gift for my father a year ago, and it's still working perfectly, thank 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 measure up to 100 meters in just 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.
