The HT-669 WI-FI borescope extends your view beyond blind spots, allowing you to see otherwise hidden areas and inspect the root of a problem. A new-generation WiFi chip provides clear, smooth image transmission. Corrosion and wear resistance support everyday underwater work and work in oily environments. It can be used in hard-to-see or hard-to-reach places for aviation and ships, vehicle inspection and maintenance, mechanical, electronic, and electrical equipment servicing, air-conditioning, pipeline and vacuum-system inspection, scientific experiments, archaeology, outdoor exploration, and household inspection assistance.
