ELECTRONICS UPDATE Raytheon Marketing New Electromagnetic Speedlog Series —Free Literature Available— The new Navi Series of Electro- magnetic Speedlogs from Raytheon offers economy and performance in a rugged, commercial-quality de- sign. Available in two speed ranges, the Navi Series is made for use aboard fishing vessels and work- boats. A large analog speed dial is switchable from 0-10 knots to 0-30 knots; or from 0-25 knots to 0-50 knots, depending on range selected. Each unit has a built-in distance indicator. Featuring standard 200 pulse- per-nautical-mile outputs, these speedlogs can be easily interfaced with satellite navigators, plotters and other microprocessor-con- trolled systems. Operation is select- able from 12 to 24 vdc. The new Navi Series is less sensi- tive to cavitation disturbances be- cause of its electromagnetic design, so that positioning of sensors is less critical. Two models are available, a Navi 3 EM Speedlog with through- hull, flush-mounted sensing unit, and Navi 5 EM Speedlog with gate valve assembly.
