by FLIRFLIR's First Mate family is the most popular line of handheld marine thermal night vision cameras in the world. They give every boater the power to see clearly in total darkness. The NEW First Mate MS uses the same thermal imaging technology as FLIR?s best-inclass Navigator II, Voyager II, and M-Series thermal night vision systems, but it?s even smaller, lighter, and more affordable than ever before. First Mate MS makes pictures from heat, not light, to help you see landmarks, bridge abutments, and other vessels clearly in all light conditions from daylight to complete darkness. Thermal night vision improves your ability to see rocks, buoys, oating debris, and even helps you nd people in the water when just a few minutes can mean the difference between life and death.
