The ROMEO4XT-PRO offers the same high-end optical performance, quad-reticle, and legendary durability of the original ROMEO4T while adding key features requested by professionals. Illumination control moves to the top, providing easy access with either hand while staying clear of chest rigs and plate carriers when slung. A dedicated night vision override switch makes short work of drastic changes in lighting conditions and by combining MOTAC with a common AAA battery, the ROMEO4XT-PRO is rated for 50,000 hours of runtime. Like its predecessor, the ROMEO4XT-PRO is IPX8-rated for waterproof and fogproof performance and is tested to MIL-STD-810 to ensure reliable service.
