A world’s first! No matter whether faced with water, dust or even if dropped, the new PR 30-HVS takes hard use under the harshest jobsite conditions in its stride and continues to provide precise, reliable readings. Four hard rubber grips not only give users a secure hold, they also absorb impacts and protect the casing that contains the electronics and precision mechanism. The PR 30-HVS is a robust and highly reliable rotating laser for virtually all kinds of leveling, aligning and grading.
