I was curious if any of you own your own tank that you just keep at home solely for cleaning your gear when you get back from vacation and for testing before you go on vacation. In addition, having a tank would allow for more practice setting up your gear when you haven't been diving in a while. My diving generally consists of one or (hopefully) two weeklong dedicated scuba trips per year with my wife and we own our own gear. A week before the trip, each day as the trip approaches, my wife and I put on and take off our BCDs, put on our fins and remove them, and we start reviewing pre-dive checklists just so that we aren't totally brain dead on that first dive.
I'm asking because I've read advice that suggests rinsing your regulator while under pressure is safer in order to ensure water doesn't get in the first stage. Plus, while I get my gear inspected every year before we go on vacation (and I can verify performance at the shop before I go), maybe it would be nice to be able to hook up your regulator in the weeks before you leave just for a final sanity check.
I doubt I would every use the tank to actually dive with and think it would be around a $300 investment. Plus the cost of the fill but also I would probably need some sort of regular testing that a shop would require in order to do a fill?
Assuming I can afford the $300 initial purchase and some sort of occasional outlay for occasional testing, does it make sense? Or am I over thinking this?
