Concept/Concept2

[zahgurim]

Am looking to buy a slightly used Concept for my girl, as her first BCD.
I have Zeagle gear myself, am happy with it, and want to stick with the brand to ensure swappability of parts if neccesary and make maintenance easier.

What are the differences between the older Concept, and the new Concept2 Pro as seen on the Zeagle site?

Thanks!

Been doing some research, and saw this.

How can I tell the difference between the new version and the old version with this problem?
If I do end up getting an older one, is it simply a case of switching wings and no longer having to worry about it?

If it is an older one, I'm not worried about swapping wings as I'm buying a larger one for myself soon anyway, and I can mount my current 34 onto the Concept for her...
