F1 Fish Finder

The Chasing F1 (and F1 Pro) is a surface-traveling fish-finder drone made by Chasing Innovation (Shenzhen, China, founded 2016). It is not a fully submersible ROV but rather a surface drone that lowers a camera/sensor payload up to 20–30 m underwater. It is user-steered via a smartphone app (iOS/Android) or optional joystick remote over Wi-Fi (30 m range, extendable to 60 m with 3B remote), with autonomous features limited to GPS-based auto-return on signal loss. The F1 Pro variant adds features like infrared lighting, EIS, and bait drop; a newer model (CanFish F2) adds AI waypoint cruise and dual-frequency sonar, but that product is in pre-order. Several extracted facts appear to be from unrelated sources (academic AUV research, a video game boat guide) and do not describe the F1 system.
