NEWMAR

NEWMAR of Newport Beach,

Calif., offers the NAV-222, an auto- matic digital direction finder for easy and precise navigation. This compact unit utilizes a microproces- sor in place of motors or other mov- ing parts, and allows signals to be locked in from either the beacon or broadcast band by a lightweight del- ta loop antenna mounted perma- nently on the cabin top or mast.

Two digital LCD displays indi- cate station frequency to the nearest kHz and relative bearing of the sta- tion to the nearest degree. The cir- cular LED display indicates the ac- tual bearing in azimuth to the sta- tion. A rotating azimuth bezel al- lows relative bearings to be con- verted to true bearings for simple navigation or homing.

The speaker can be remotely lo- cated for maximum audibility, while the processor unit can be tabletop-, overhead-, or bulkhead-mounted.

PUROFLOW MARINE

Puroflow Marine Corporation of

Newport News, Va., manufactures power-line filters that provide es- sential protection for shipboard communications and navigation sys- tems against harmful voltage surges and noise in ships' mains. Modern, solid-state electronics systems are extremely vulnerable to voltage transients and electromagnetic in- terference (EMI) that can cause these products to fail or malfunction without warning. It is estimated that voltage fluctuations may be responsible for as much as 60 per- cent of all service calls for marine electronics equipment.

Puroflow estimates that the aver- age shipowner could save thousands of dollars annually by adding proper power-line protection aboard ship.

The company offers an extensive selection of power-line protection devices, including voltage surge sup- pressors and EMI/RFI filters. These filters are designed to react within nanoseconds to shunt away harmful overvoltage surges and remove un- wanted noise from ships' mains.

The bi-directional, multi-stage filters were originally developed by

Puroflow to protect sensitive mili- tary electronics systems for the U.S.

Navy. They meet all military speci- fications for power-line condition- ing, including tests for vibration and

RACAL-DECCA

The Racal-Decca Master Radar series is a "building block" radar system that can be configured as a 16-inch relative motion radar and upgraded with modules to add anti- collision true motion and automatic radar plotting aid (ARPA) capabili- ties.

This modular approach gives de- sign and production economies and a wide range of usage applications.

As a result, Master Radar systems meet or exceed IMO standards, but can cost less to buy, upgrade, and service. Purchase and maintenance economy are achieved without per- formance compromise.

Racal-Decca ARPA technology has been extensively proven in oper- ation around the world. Master Ra- dar capabilities include automatic target tracking and collision-predic- tion alarms, pre-plotting of trail ma- neuvers, Cleanscan videoprocessing for best foul weather picture, bright recycled video, and easy-to-use "operator-proof" programming.
