Ideal for Navy and Coastguard Ships, Freighters, Merchant Marines and Shipping boats, the FLIR MS224 First Mate Water-Proof 240x180 Handheld Thermal Monocular 0008-02-00S is an incredibly compact, easy to use thermal imaging device that will help you see clearly on pitch black nights on the open ocean. That's because these FLIR Systems Maritime Thermal Imagers detect heat signatures, not light, with their 240x180 VOx microbolometer thermal detector, delivering an always-crisp image with its advanced internal camera software. Weighing just 340 grams with a battery, these small Waterproof Thermal Imaging monoculars are extremely compact and rugged, achieving an IP67 environmental rating, that allows the device to take a beating from powerful projected waters without being damaged. The ergonomic design and intuitive controls (the monocular is operated by four buttons on the top of the unit) make the FLIR Systems MS-224 First Mate Thermal Imaging Monocular usable by everyone from salty veterans to weekend pleasure-seekers to government and shipping boats that need additional protection from theft. When you want to perform small tasks around your boat but don't need to activate the full thermal power of the monocular, the Flir First Mate Waterproof Maritime Thermal Imaging Monocular has a small LED task light that will illuminate a small area in front of the monocular. FLIR Systems has designed the monocular to operate for up to seven hours on a single charge, and it can be re-charged with a simple USB cable connection. Professional-grade handheld thermal imaging just got affordable with the FLIR MS 224 First Mate Compact Thermal Imager.
