Weather radar / dry hail

[Mach trim]

1)For those of you who are familiar with the older Bendix weather radar. When should one be in the NORM mode and when should one be in CONT ?

I take it CONT is better at painting bigger cells but the NORM has a more accurate narrow beam for the light stuff.... ?

2) Could someone please tell me more about dry hail.... Which one cannot pick up on weather radar ?


Thanks in advance and blue side up
