Fully automatic

Whether you choose to navigate with the present Loran A system or the up-and-coming

Loran C system, you can do it faster, easier, and more'accurately with our DAL222 or

DL91 Dual Automatic Receivers. When compared with other Loran receivers the simplicity of our uncluttered front panels tells the story: no gain controls, no attenuators or level meters, no drift or sync knobs, no

AFC switches. The advanced solid-state computer circuitry used in both units does it all for you...automatically.

Faster, easier, more accurate

With either system, just select the desired stations and you get a precise fix from two digital LOP readouts. Your position is then continuously tracked, updated, and displayed ...automatically. Furthermore, DL91 is the only Loran C receiver that functions without pre-setting approximate LOP's.

The most precise, longest range Loran C

Unlike many combined Loran A/C units,

DL91 is a cycle-matching receiver specifically designed to make full use of Loran C transmissions. Accuracy of Loran C groundwave fixes varies from 100 feet at short range to 500 yards at 1000 miles from stations. DL91 has a special extended range mode that provides an additional 250 miles of groundwave coverage. Skywave coverage, especially at night, extends out to 2500 miles.

DL91's repeatability, accurate to within 50 feet, lets you return to the same position every time.

The ultimate Loran A

Along with fully automatic operation,

DAL222 has special solid-state circuitry that minimizes interference. As a result, both 1 j Q * : j . : : u I i " || - ' msm • § 1 I

Each LOP is then updated every 31/2 seconds. DAL222 also has a unique memory circuit which can freeze selected LOP readouts for later reference or log entry, while automatic tracking continues.

Compact, lightweight

Whether you choose DAL222 or DL91 (or both if Loran A and C coverage is desirable), you'll find them exceptionally light, compact and capable of mounting almost anywhere- table top, overhead, console, bulkhead, vertically, or horizontally. Both units have complete manual back-up controls. Remote dual display units and outputs for driving plotters and data processors are available.

We make our 2-year on-board guarantee work

Completely solid-state, both of these

American made Loran receivers use plug-in modular circuit boards and integrated circuitry for maximum reliability. However, if they ever need servicing, during or after the two-year guarantee, you can depend on the factory trained technicians of over 100 nationwide ITT Decca Marine dealers—and our world-wide service network—to have you underway quickly.
