We rarely discuss actually using emergency gear, but that is an important aspect of preparedness. An emergency is no time to be taking a gadget out of its wrapper and reading the manual. Get familiar with your stuff and with what it can and and can't do. Packs should be adjusted and known to be comfortable,shoes should be broken in, etc. This aligns with the notion that EXPERIENCE is really critical in dealing with problems.

Go out and use your gear, preferably in as realistic a situation as possible....
