RDI Circle 27 on Reader Service Card Radar Devices, Inc.'s advanced automatic radar plotting aids series RDI ARPA I and RDI APRA IV sig- nificantly reduce costs of installing collision avoidance radar systems aboard all vessels of more than 15,000 gross registered tons to meet International Maritime Organiza- tion's (IMO) September 1988 dead- line. Ships' owners realize these cost savings when they retrofit RDI ARPA I or RDI ARPA IV to their ships' existing radar instead of buy- ing expensive new radar systems with costly built-in collision avoid- ance systems. RDI ARPA I is one of the world's most economical add-on ARPAs that puts computer-generated ARPA symbols and vectors on al- most any marine radar display, meeting IMO's requirements. The easy-to-use system is interswitch- able between two existing radar dis- plays and offers a 10 or the new GA- 20 target tracking system with man- ual, semiautomatic or full automatic guard zone acquisition, with Radar Devices' patented Guard Zone warning alarm. With its own very bright 16-inch CRT, the RDI ARPA IV is one of FOR MARINE USE Safety Treads & Safety Surfaces WOOSTER PRODUCTS INC. manufactures the complete line of Anti-slip Safety Products for ships' ladders, decks, ramps, showers, galleys, gangways, passageways.

The basic 20 target RDI ARPA IV system automatically tracks radar targets which are ac- quired manually, semiautomatically or automatically by Guard Zone System. The radar information is displayed in the form of target echoes, track symbols, history points and vectors. In addition, the RDI ARPA IV is designed to serve as a second display or simply be an ARPA add-on to a ship's present radar.
