Patent ID: 7272908

Claim:
A fishing float, comprising: a housing constructed of a buoyant material for floating on a water surface, said housing having first and second portions, said first portion having a configuration for facing downward when said second portion faces upward, said second portion having a configuration for facing downward when said first portion faces upward; a first battery mounted in said housing; a first light source positioned in said first portion of said housing and electrically connected to said first battery; a second battery mounted in said housing; a second light source positioned in said second portion of said housing and electrically connected to said second battery; a first orientation switch electrically connected to said first light source and to said first battery for automatically energizing said first light source when said housing first portion faces downward; a second orientation switch electrically connected to said second light source and to said second battery for automatically energizing said second light source when said housing second portion faces downward; a first depth sensor positioned in said first portion of said housing and electrically connected to said second battery for generating water depth data when said housing first portion faces downward; a second depth sensor positioned in said second portion of said housing and electrically connected to said first battery for generating water depth data when said housing second portion faces downward; a first CPU electrically connected to said first depth sensor and said second battery, said first CPU having means for actuating the transmission of first depth signals corresponding to respective water depth data generated by said first depth sensor; a second charging coil electrically connected to said second battery for inducing a current and charging said second battery, said second charging coil electrically connected to said first CPU for transmitting said first depth signals; a second CPU electrically connected to said second depth sensor and said first battery, said second CPU having means for actuating the transmission of second depth signals corresponding to respective water depth data generated by said second depth sensor; a first charging coil electrically connected to said first battery for inducing a current and charging said first battery, said first charging coil electrically connected to said second CPU for transmitting said second depth signals; and a receiver unit remote from said housing and having a receiver for receiving said first and second depth signals, said receiver unit having a user interface for indicating said corresponding water depth data determined by said first and second depth sensors to a user.
