I must confess, the PLR 15 has topped my expectations! He really is so small and light I was unaware (just 10x3,6cm!). You can put in your pocket (at least in the working trousers) it actually.
In terms of accuracy of the PLR PLR 50 is 15 by no means. Both deliver perfect results in the distance measurement. Only in the functional scope of the PLR 50 is considerably larger. The PLR 15 may provide only basic functions, distance measurement and continuous measurement, but in Allteag often sufficient. It can even be stored, the last measured value.
And the operation using the one-button is completely self-explanatory. And additional 2 AAA batteries are included, incidentally. The display is actually very readable.
For me, the part is fully recommended!
