That's by far the easiest pulse to find. Though, from my training, I'm always feeling for breath while taking a pulse at the same time. For first aid reasons, usually the reason you take a pulse is to gauge whether you need to give CPR - and if they don't have a pulse to begin with, there's not really a point in CPR.

Plus, most people with existing medical conditions worth mentioning usually wear a bracelet. I feel this would fall into the same category.
