Warms tips:
1. As strong sunlight would weaken laser energy, which
might influence the accuracy and measuring range, so we
recommend you to avoid using in a direct sunlight. If have
to use, we kindly recommend to put a smooth and opaque
reflective plate.
2. Measurements taken through transparent objects like
glass, water, crystal etc, powerful light sources, strong
light-absorbing objects or other highly reflective surfaces
may be inaccurate. Please use our attached target card.
