Expect very useful aid but no miracles

I had no desire to measure longer distances with the ruler or tape measure 5 m, given that many were primarily to measure longer distances through various projects at home and I generally sometimes wanted to survey the land suggested I.
I'm really surprised in terms of accuracy. All sample measurements that I made up to 15m was the determined value well within the Tolerance of + - 1.5 mm. What is at first a relatively large sound over short distances in my opinion, of course, is relative to each meter more. Since the device has the + -1,5mm also at 80 meters the deviation is seen very low. Such routes conventionally measured result certain deviation several cm.
The angle indicator also works quite well, for most major work safely enough.
Positive also the surfaces, - space, - and other measurement functions. Ruckzuck the square meter Number of living rooms is determined. In addition the last 20 measurements are saved. These can be added or subtracted to new measurements or stored values ​​or.
However, indierekten measurement functions work only approximate. Even with meticulous measurement procedure adds up to Tolerance of length measurement or the angle measurement. The longer the distance is that I want to measure indierekt the greater the inaccuracy. With 4m height, there were already several cm.
The laser could be brighter because of what the emission class is not likely possible. But then at least ne sighting device for a chance to have to find the point at greater distances.
In cloudy daylight I depending on surface real problems the point in 15-20m Entfrn. yet to identify. 80 meters so rather progresses Twilight using a tripod and remote Glass (but quite possible).
Oh and the trigger could go really easily. Depending on how the device is held and how far and large the surface to be measured is blurred to measure continuously during, but can help with the shutter lag.
Other than that I like the unit well (weight, dimensions, processing, display illuminated and even rotation, battery life, measuring pin for measuring from corners).
The green version or the hardware store products are hardly less expensive but have higher tolerances, no protractor and measure just between 20-40m wide.
On the whole, I am quite happy.
