If you're into adventure sports, traveling far from home, driving off-road (or even on freeways), handling firearms, etc.—or if your access to medical services could be delayed, you need a more advanced medical kit.
When it comes to serious injuries including broken bones, life-threatening cuts, puncture or gunshot wounds, and other serious medical incidents, a basic first aid kit won't do.
Having the right gear is essential—but knowing how to use it is critical. With the right training, you can not only reduce the amount of gear you need, but be more effective with it.
