Abstract
An electronic instrument capable of measuring the depth of operation
of fishing gear or any other object in the range 0-100 m with an
accuracy of ± 1 m is described. The main components of the
instrument are a hydrostatic inductive type pressure transducer and
an electronic solid state indicating meter. The range of measurement
can be extended considerably (up to 1000 in) by making easy
adjustments in the instruments. The advantages of the instrument
over those currently in use are its light weight, ruggedness and low
cost.
