It is designed to save significant time and money on the job site. It has 20 powerful built-in functions with audio indicators and BlueTooth for optional SmartLink App to instantly create tables, profiles, sections, 3D or topo maps directly from your measurements. Saves up to 10,000 internal memory with 2-3 years 9V battery life of typical use. ZIPLEVEL is extremely fast and easy to use, has numerous powerful built in functions and is built job site rugged. Now, contractors can use the sub-millimeter performance of ZIPLEVEL over unlimited ranges to precisely level, set pool negative edge or read floor or foundation deviations. Engineers can easily measure real-time beam, floor or bridge deflection, plants can precisely level equipment and shops can build projects of any size without line-of-sight or distance error. Since 1996, ZIPLEVEL has become the de facto standard in many applications and is used in all phases of construction worldwide. The possibilities are endless. Material: Plastic.
