Overview
CHASING M2 PRO MAX is a professional underwater ROV designed for 360° omni-directional maneuvers and deep-water work to 200 m (656 ft). It integrates five accessory ports (mount up to five tools at once), a fast slide-in quick-mount system, and second-generation anti-jam motors. Imaging is handled by a 1/2.3" CMOS 12 MP camera with F2.8, 150° FoV, 4K30 video with EIS, and dual 4,000-lumen (8,000 lm total) 5000–5500 K floodlights. Power options include the onboard 300 Wh battery (up to ~4 h) or a shore-base power supply (200 m) for unlimited runtime. Typical uses span emergency rescue, hull/dock and offshore wind inspections, aquaculture, hydropower, and scientific exploration.
