I often get strange looks when I pull out the old CR-5 and even get the occasional "what is that?"
I really like the CR-style over the E6B. More compact and no parts to slide out and get lost in the rudder pedals. I keep my CR-5 in my flight bag but rarely use it.
It's incredibly accurate and 7 x 9 is still 36...! Hell No! Wait...
The answer I'm getting is 6.3. Wait! 630. Or is it 6300? No, I got it now. 7 x 9 = 1:10!
