By all means get some training but if you’re going to purchase tourniquet, emergency bandage ( Israeli) and the like get more than one. You need to sacrifice one to practice with. A one day first aid course is useful, watching YouTube videos not so much. But familiarity with the gear is what’s needed when the shit happens, otherwise you get a ‘WTF do I do with this’ moment when the pressure comes on. Most people carry this stuff packed away and never looked at because they’re too tight-arsed to sacrifice $30-$60 dollars to break the seal and practice.
