Dual Range Radar Operation - Raymarine E90W User Reference Handbook

9.6 Dual range radar operation

The Dual Range radar function enables you to view 2 ranges at the
same time in separate windows. The function is only available with
HD and SuperHD radar scanners.
Using your multifunction display and an HD or SuperHD digital
radar scanner, you can view either a short or a long range image in
separate radar windows.
The default setting is Long, which provides a standard scanner
range.
Limitations
• Dual Range operation is not available if MARPA targets are active.
• You cannot acquire MARPA targets if Dual Range is enabled.
• Chart-sync and chart overlay are temporarily disabled when Dual
Range is enabled.
