Abstract
An on-line fishing depth indicator is adapted to be placed either in series or in parallel on a typical fishing line in combination with fishing bait. The indicator is adapted to sense and store the maximum depth of a bait during a trolling operation under controlled conditions. The indicator is activated by a remote activation switch by placing the indicator in the proximity of a non-invasive, remote activation element. The electronics, pressure transducer and visual readout are contained in a shielded, water-tight, encapsulated compartment within the unit.
