Henry Co., Inc. of Moores- town, N.J., has been awarded a contract from National Steel and Shipbuilding Company to provide design and engineering services for the development of drawings for the AD-44, a 643-foot, 22,260- ton destroyer tender. This fourth ship of the class being built at Navidyne's new ESZ-7000 looks more like a satellite navigator than a Loran C. With good reason. Much of the same technology that made Navidyne's satellite navigator the world's best went into our new Loran C Navigator. So no wonder our Loran C doesn't look like any other. It's more advanced than any other. IT LOOKS TOO SIMPLE TO BE SO SOPHISTICATED. The ESZ-7000 is the soul of sim- plicity because at its heart is a very sophisticated microcomputer. One that puts on our Loran's screen everything a navigator could want to know. The date,precise time,present latitude andlongi tude,course and speed made good,and Simple initialization: Turn on...enter GRI...Period. course and distance to any of nine preselected waypoints for both great circle and rhumb line routes. Also the total distance run and estimated time of arrival. Even left-right steering com- mands for maintaining a precise predetermined course. All this. All displayed at once. Eliminating switching and look- up codes — and a large measure of human error. IT LOOKS TOO BEAUTIFUL TO BE SUCH A WORKHORSE. Our design meets all U.S. Coast Guard requirements, of course. And much more. Sealed membrane switches, instead of pushbuttons, keep salt and moisture out. The number of components has been reduced by ad- vances in electronics. And factory burn-in re- duces chance of failure to a minimum. Result: A Loran C receiver so rugged and reliable that we back it with a full three-year warranty. And if you ever need service, count on world-wide Navidyne shipboard service in nearly every major port. IT LOOKS TOO EXPENSIVE TO BE SO AFFORDABLE. By now, you probably think this is the most expensive Loran Con the market. Not so. Compare its features to units costing far more — and there's no comparison. The ESZ-7000 sets a whole new standard. TWO WAYS OF LOOKING AT THE ESZ-7000. LOP reading also available as well as LAV LONG. If warnings indicate possible tracking problems, you can easily change from the fully automatic latitude/longitude-reading screen to a display of up to five time differences (TDs) as shown here. With all pertinent information about the condition of each signal. A simplified version of the ESZ-7000 is also available which displays Loran C time differences only. But even it offers more information at a glance than any other Loran C. In fact, any way you look at our new unit, you find it's worth a closer look.
