A fishing float includes a housing having first and second portions. The housing first portion may contain a first light source and a first depth sensor. The housing second portion may contain a second light source and a second depth sensor. The housing may include a battery, orientation switch, CPU, and charging coil. An optional remote receiver unit includes a receiver and an interface. After the housing is cast, the orientation switch completes a circuit that automatically energizes the downward-facing light source (whether first or second). The corresponding downward-facing depth sensor (whether first or second) generates water depth data. The CPU may actuate the upward-facing light source to indicate the water depth data and may actuate the charging coil's transmission of this data to the receiver unit. The housing rotates when a hook is struck, flashing the downward-facing light source. Inducing current in the charging coil may recharge the battery.
