Where, exactly, is my second vertebrae?

Green,
It's not necessarily an exact science, it's a rough starting point to determine if a diver can reach back without physical impairment. The 2nd vertebrate is just below your neck about 4 finger lengths down. Essentially, all you are trying to accomplish is to get an approximate area where the valves would be when kitted up. We use the 2nd verterbrate as a generic starting point.
Hope that helps..
Regards
