Great versatile chronograph for zeroing in your airsoft rifle. Test modes available are for switchable from .20 gram to .25 gram BBs. View readings in Feet per second, or meters per second.  Also another great feature is you can read rounds per second. Many airsoft fields limit BB speed for insurance safety reasons so this tool is invaluable to setup your gun prior to leaving your home, and or in the field.  Low cost time saving device.  Here at 6MMZ.COM we are including a tri pod with the chronograph at no extra charge until supplies last.  Requires 4 'AA'  batteries which are not included.
