The FX-380 Wireless Shutter Release Kit operates at 2.4GHz frequency which gives the user a longer working distance (up to 220 feet) and less potential conflict with other frequencies. The FX-380 features an Auto Coupling Capability (ACC) channel setting ability which makes syncing the transmitter and receiver easier than ever by just a push of the button. A time-lapse function has been built into the wireless remote to give the user more photographic options in one handy device. The built-in magnetic poles on the transmitter and receiver help the user keep them together when not in use.
