InstAlertTM, the new safety enhancing software upgrade for Raymarine’s TH Series handheld thermal cameras, automatically highlights in red the ‘hottest’ objects visible. Using the new InstAlert mode means that a person in the water now stands out in bright red against a black and white background; a quick and easy spot in an emergency situation. Available as software upgrade file 03.13.00.dfu, the new InstAlertTM detection palette can be added to the feature profile of both new and existing TH Series products and offers four pre-set levels to optimize the image contrast for maximum target definition. Making pictures from heat, not light, the rugged and affordable TH series cameras show objects, even ice, through the thermal energy they emit.
