The Umarex T4E X-Tracer is specially designed for rubber and pepper projectile guns.
Its primary function is to accurately mimic the muzzle flash of real firearms by briefly illuminating the exiting gas with external orange LEDs when fired.
The second function is provided by the internal UV LEDs. When using Performance TRB series fluorescent ammunition, the balls are lit up as they pass through, providing a good overview of their trajectory during flight. This function is more suitable in low light conditions.
You can switch between the functions by holding down the button located by the M22x1,5 thread. You can therefore choose only the external LEDs, only the internal LEDs, or all LEDs at once.
The device is powered by an integrated battery that can be charged with the supplied USB-C cable.
The X-Tracer .68 model is compatible with the shotgun HDX68 ( newly called TX68) and doesn't require any additional adapters for installation - it is screwed onto the original thread on the barrel.
