The Garmin GMR 20 Radar uses a 2 kW radome that provides a 3.6-degree horizontal and 25-degree vertical beamwidth to deliver accurate target acquisition and better penetration through rain and fog. For fast presentation of radar signatures, the radome processes the raw data and sends it to a networked multi-function display – Garmin recommends the GPSMAP 3006C or 3010C chartplotters. Radar features include automatic and manual sensitivity and tuning controls. Designed to work with the Garmin Marine Network system, the GMR 20 sells for $1,919.99.
