FEATURES
-Convenience-
Measuring angles quickly with accuracy of ±0.3 degree. (±0.3 degree means the measure result may be either larger or smaller than real angle by 0.3 degree at max. Total difference between two measurements may be as much as 0.6degree)
Digital readout displays angle in 1-decimal.
Easy operation with only two buttons.
Good locking function could lock the measurement at any angle.
Compact structure to achieve convenient carrying and using.
-Multifunction-
This angle finder ruler could both measure angle and length, metric and imperial scale.
Woodworking: adjusting angles of table saw, miter saw, band saw etc.
Construction
Sketching, drawing
-Practicability-
Rulers of this digital angle finder made by durable brushed stainless steel.
The angle finder could be well used to various fields instead of angle ruler, straight ruler and square ruler etc.
Easily drawing line with the stainless steel rulers.
