Chasing M2 is an underwater drone designed for use in rough waters and can maintain the selected diving angle for video and photo recordings even in choppy conditions, thanks to its self-leveling feature. Chasing's patented anti-stuck motor technology minimizes the risk of individual drive motor failure, which can occur due to stirred-up sand or other sediments, ensuring safe operation. Additionally, the existing expansion system allows for the use of additional cameras or other devices. The battery required for operation can be quickly replaced via a waterproof quick-release mechanism when needed. With a single battery charge, it can dive for up to 4 hours without interruption.
