When it may not be suitable

This flashlight is not intended for deep-water diving or prolonged submersion, as it is rated for IP66 water resistance rather than full underwater operation. Additionally, users requiring extremely high-intensity long-range searchlight capabilities may find the beam profile more suited for general area illumination rather than long-distance spotting.
