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 read and store the maximum depth of the bait during a trolling operation under controlled conditions. This permits the user to determine the performance of the bait under certain, predefined conditions. The electronics and pressure transducers associated with the indicator are self-contained in the unit.
