Finding fish from the bank is guesswork with better marketing. The F2 is a small surface craft that goes and looks: a pan-and-tilt camera reaches 30 metres down and pans 320 degrees with 115 degrees of tilt, dual-frequency sonar (310/110 kHz) maps from 0.6 to 100 metres, and on-device AI turns the returns into recognisable fish arches rather than noise. It builds contour maps as it goes, remembers GPS spots so you can return to the same rock next week, and can drop bait on command. It is a survey vessel shrunk to backpack size, and it answers a question anglers have always had to guess at.
