All of the kits are great, but without solid training on how to use it, you are not even half way there. Having the biggest coolest first aid kit is worthless, if you don’t know what to do with the contents. I have found that something as seemingly simple as a tourniquet can actually be a problem. People know in therory how it is supposed to work, but underestimate drastically how tight it needs to be to work. I’ve been a fire/medic for well over 20 years now, and I can’t stress enough how important it is to go take a class on how to use the emergency gear you carry.
