Take extra peace-of-mind with you on your next run thanks to the NU43's SOS and beacon modes in addition to a slow-flashing red light mode that will flag down passersby if need be.
This is an excellent running companion due to its incredibly light design and its IP68 weather rating which will persevere through storms of rain and sand alike.
State-of-the-Art Optical System — 400+ Feet of Throw
The unibody optical lens build of the NU43 houses a multifaceted reflector responsible for the soft, even glow of the TrueVision beam which can be viewed for hours with minimal eye strain. Additionally, you can switch over to the red light outputs which preserve your natural night vision and are exceptionally useful in serving as a personal locator in case of an emergency.
