GemRed depth gauge and protractor kit #GR903 includes 82305 Digital Angle Finder 200mm*1 and Digital Depth Gauge*1

Both of these two measuring tools are the most useful gadget s in your workshop.

Digital depthe gauge is for measuring the cutting depth or height on material.

【Accurate Data】 The GemRed digital angle finder applies world's first Capacitance Displacement Transducer patented technology, to ensure the accuracy of data up to ±0.3°. Hinge mechanism on the angle rule allows a full range of 0 to 360-degrees to measure inside outside and reverse angles.

【Simple & Easy Used】 ☆The Angle Finder Tool both measure the angle and length, metric and inch display. Calculating quickly and accurately, avoid tedious calculations, never guess or eye ball the angle and length again with one convenient tool. ☆The angle measure tool with large LCD display, read clearly. ☆Also easily operate with only 2 bottons.(The red and white buttons make the function distinction clearer and more convenient.)
