- Not having gear serviced frequently?
In my experience (not in diving, but just general life experience), this is the easiest one to fall into. In all things, probably most of us meticulously care for our things when they are brand new, but gradually take less and less care of them once the newness wears off. I service equipment for a living, and when learning, every step gets followed verbatim. But after performing a task for the umpteenth time, we start rushing through, doing steps from memory, etc. The problem is, most of the time this type of thing won't get somebody killed, so this type of thing gets overlooked. But in diving, it can get somebody killed. That's why pilots have checklists they have to follow. If you do things by memory, you tend to forget little details... like remembering to put the landing gear down.
Do any of you actually have a printed checklist of some sort you go over before a dive, or is that going a little overboard? I suppose for a simple OW dive that only goes down 50', it's not as important as surfacing is relatively simple be it through buddy breathing, or a controlled emergency swimming ascent. But how about for the more technical dives?
