ingeniously simple and very accurate incl. Tip

The settings are easy to carry out - and especially logic.
The pressure points of the buttons are ok.
With 3AAA you come out forever.

The measured distance is 25m just OK. Other routes can also be measured when one considers a few things:
- Not be measured in the extreme brightness
- Best take the device somewhere or fasten it with a clamp (clamp hardware store with spring 3 euros) to a tripod
- The importance of a target point which best consists of a black / white reflective film (just experiment)
- The film as a destination point either glue or with a plug rod / stand somewhere

This allows increasing the distance and you can therefore measure out distances.

Accuracy is very good. Each steel measuring tape is inaccurate to classes because the temperature and the laborious measurements most errors caused (unless one takes temperature-independent measuring tapes).

Conclusion: very good device with sufficient functionality and high accuracy. Purchase is recommended.
