How many have avoided hitting something at night because you saw it on
radar?
I have a 2006
Raymarine E80
radar. After hating it for two years, I've learned how to get it to perform pretty well, in that it will show "stuff".
Now how much it picks up all depends on the sea state.
It takes careful adjustment of both the gain and sea state values.
I also adjust it so it does best in the short range, meaning minimal false alarms, but it will see anything within 1/4 mile.
At night, i also always set the
alarm. I do a 15° to 20°, 3000 ft to 2800 ft.
Alarm 2 is a 330° almost circle around
boat, from 1500 to 1200 feet. Any closer and it produces false alarms.
The alarms only went off at night a few times from the
Canaries to the
Panama Canal.
