I have both scanners. Much prefer the SDS100, the display is much easier to read. Really like the ability to charge it while scanning. To my ear the 100 has a bit better audio.
Bcd436hp/3600xlt all the way. It's slimmer and takes AA batteries if there ever were to be a disaster it could still work. Once the sds 100 battery is dead that's it unless you have multiple 70$ batteries. The sds100 battery clip also breaks very easily.
It will definitely do air band. But it is designed more for digital systems and a such operates better with them. An analog scanner would be the best option if you only want to monitor airband. I'd say the 125at or sr30c would be a good choice, or their equal European versions.
