And Alden's new Marinefax" TR I gives you the information you need to plan your best and safest course. A Wealth Of Information With your Marinefax TR I, you can receive a wide variety of charts, available free from over 50 govern- ment transmitters worldwide. Charts not just on weather, but on sea conditions as well. Surface an- alyses and prognoses let you avoid storms or take advantage of favor- able winds. Gulf Stream and other oceanographic charts, as well as wave height and direction charts, show you the speediest and most comfortable course. Beyond comfort and safety, weather charts can help plan a course to minimize fuel con- sumption. And fishermen will especially appreciate sea tempera- ture information to show the most likely hot spots. Automatic Reception Marinefax TR I is a new genera- tion of weather chart recorder from Alden. It features a unique micro- processor that lets you program the recorder to automatically receive the exact charts you want. You tell the recorder when to come on, what frequency to receive, when to change frequency, and when to go off. You get your maps, whether you're onboard or ashore. Programming is easy, with the LCD display leading you through the steps. Yet despite this sophisti- cation, Marinefax TR I is the smallest weather chart recorder on the market. Improved Frequency Selection Recall any transmitter frequency you like just by hitting two buttons. Or store up to ten stations of your own choice for one-button recall. And the TR I has a new, improved radio. Fine tuning is incredibly sim- ple: just push the button for precise, 0.1 kHz changes until you optimize reception. The frequency then locks in, eliminating the "drift" common to many other radio receivers. New Paper Our new Alfax thermal paper is dry for easy storage, and produces bright, high- resolution maps. Thermal printing is exceptionally quiet, - and provides for simple and inexpensive operation.
