The Sentinel is also a slim-profile powered earmuff. It too has a fold-away, fully-adjustable, padded headband to fit a wide range of head shapes and sizes. The Sentinel has front-facing microphones that amplify hearing, while Rapid Noise Suppression technology reduces harmful noises down to a safe level. An auto-shutoff feature turns the power off after four hours on continuous use to extend the life of the two AAA batteries (included). The Sentinel offers an NRR rating of 26dB and has a 3.5mm AUX input jack for use with mobile, MP3 and other devices. The Sentinel is perfect for operations where cell phones or radios need to be used to coordinate team members. It is also ideal for range use for those that like a little music while sending rounds down range.
The Sentinel is available in Black and Powder Blue colors.
