Garmin is pleased to announce the new highly anticipated GMR 404 and GMR 406 open array radar. Both systems offer a powerful 4kW, 72 mile X-band digital radar designed for use with the Garmin Marine Network. They offer outstanding clarity, precision and target definition. The GMR 404, 4-foot scanner focuses on targets with 1.8 beam width while the GMR 406, 6-foot array takes beam width down to 1.1 for even greater target separation. Combined with an elegant industrial design, these systems will certainly be a complement to today’s modern boat designs.
