Raymarine RD424HD HD Digital Radome Scanner
Raymarine’s new HD Digital radome scanners combine the power and clarity of
HD Digital signal processing with an ultra-compact scanner suitable for all
types of vessels. Compatible with C-Series Widescreen, E-Series Classic,
E-Series Widescreen and G-Series Multifunction Displays, these radomes offer a
256-color radar display and the clearest, most lifelike radome presentation
available from any radome scanner.
The Raymarine RD424HD feature the same adaptive digital receiver technology
found in our open array antennas. By adjusting automatically to changing
environmental and sea conditions, the HD Digital radomes provide crisp, accurate
contact echoes at short ranges, as well as outstanding long range performance up
to 48 nautical miles.
- Adaptive digital receiver automatically adjusts to changing
environmental and see conditions for a dramatically clearer picture
- Fast digital receiver processor
- 256 color multi-level target display with selectable color palettes
- New High Speed Mode (48 RPM) automatically engages for optimal tracking
of high speed targets at short ranges
- Dual-range mode allow you to monitor both long and short ranges
simultaneously with a single scanner and display
