Lightweight and durable construction The digital angle gauge uses an ABS shell for a sturdy, lightweight body that stands up to daily use in workshops and on job sites. Easy to use Powered by 2 AAA batteries (not included) with a simple onebutton interface for effortless measurements, making it quick to start and operate. Flexible angle and slope readings Switch between angle and slope readings and convert between relative and absolute measurements at any holding point. Clear, straightforward controls keep operation intuitive. Battery saver and stable mounting Automatic shutoff after 5 minutes of inactivity saves battery life. The builtin magnet allows stable adsorption on the measured parts, reducing movement for more reliable readings. Portable and versatile Compact size for easy transport and storage. Use it on its own or with other measuring tools to extend your measurement range. Suitable for both DIY enthusiasts and professionals.
