ABSTRACT:
A scale particularly for weighing fish which is portable and normally hand held and which includes a strain gauge for sensing the weight of a fish and the strain gauge providing a leg of a Wheatstone Bridge to provide the measuring of the strain placed upon a member to which the fish is attached. The unit includes battery sources for the required power and includes an LED display unit for reading of the weight of the fish. A zero set may be incorporated in the circuitry or a reset to zero reading may be provided. The unit provides a portable, accurate scale for weighing of fish and the unit may also include selective sensing circuitry for reading of other inputs such as temperature of water.
