My old Pro 2006 still delivers signal well. Even with a 3 ft. telescoping antenna it hears c17's at 150 NM--sometimes--, and surprisingly gets Helos 30 miles away on 123.025 Helo common.
My favorite mil air scanner is an old RS 2045. very good radio, and low band DXer as well. 35$ at a flea market. I have had 2 BC 780's, which have a good rep. , but I was not overly impressed. The remaining one seems a bit deaf now.
For me, the BC125 is an excellent scanner. It is very tough, important in a handheld. I usually do not use it for mil air, but when I have, it performed very well. There is a minor quibble on that radio, since a small slice above 380 MHZ on mil air is excluded. This has not been an issue for me.
On both the Pro 2045 and the Pro 2006, my display backlight is gone, but they work well.
