I would only use the one we had issued when I was doing an event. That way I could walk away from the unit and have the small essentials. I would have several pairs of gloves, trauma shears, pen light, note pad/pen, and a CPR mask.
I too find it odd you are required to carry one on the unit but aren't told what to put in it.
As a student you should always have tons of pens (black only), notebook for taking notes, an ECG ruler, and any protocol/info you think you might need...
