Featuring a 360-degree swivel mechanism and an adjustable padded clamp, the NS Micro offers optimal viewing angles and positioning flexibility.

The NS Micro also features an easy-to-read color-changing backlit display, which is easily seen in dark scenes or in direct sunlight. Maximum battery life is ensured by the auto-off function, which automatically turns off the tuner after a few minutes to preserve the life of the CR2032 battery (included).
