Yup thats the one! I'm an EMT-B. Its awesome that you're doing the course! When you go on your first tour on thursday don't be afraid to ask questions. Ask tons of questions and take initiative into doing some your skills on the field. Don't be afraid to step in just to take vitals. Plus, make sure u got all your gear(watch,scope,cuff,penlight, ect). If you don't know how to do something or you're unsure, always ask one of the techs for help. As far as the GPS is concerned, for that price you should jump on that and buy it!
