Yes. the Swift comes with an adjustable head strap included, but it can also be mounted to a helmet with the purchase of either the Nightfox Click dovetail adapter (compatible with G24-style helmet mounts) or a GoPro compatible helmet mount. How does digital night vision work? The Swift emits infrared light (IR) using two LEDs, invisible to humans. A digital sensor picks up the IR. The image displays on a screen in the viewfinder. The Swift isn't damaged by sunlight, has a colour display in daytime, black & white at night. What is the range of the Swift at night? Does it work with an infrared flashlight? The Swift uses two 850nm infrared LEDs, and has a range of approximately 75 yards depending on conditions. This range can be boosted with a handheld IR flashlight (such as the Nightfox XC5) to around 180 yards. What is the weight of the Swift? The Swift has been designed with head mounting in mind, and we've made it as light as possible: Just 12.7 oz. This weight includes the integrated lithium battery. Can the Swift be used whilst charging? Yes, the Swift can be used while in use with any USB power bank (the sort you would use to charge your cell phone). Just make sure the Swift is turned on before you plug in. Which Nightfox is right for you?
