The standard half-circle head is marked off in 2 ½ degree increments in either direction, allowing you to use this tool in any configuration.
Made of durable black aluminum construction with white radio-opaque markings (meaning that they'll show up on X-ray negatives), this goniometer is small enough to be slipped into a man's breast pocket comfortably, but large enough to be useful for any joint range-of-motion or axis-of-motion measurement. The white-on-black typeface is especially easy for those wearing glasses to read.
