I keep my dive time alarm on deep air dives. I always worry I might get sufficiently narc'ed I don't realise I am overstaying my planned bottom time.
I also keep my ppO2 alarm on. Just in case.
why hate safety devices?

Every now and again I play with the alarm settings on my computers, but I always disable them again before I go diving. I can't think of any circumstances when an alarm would be useful to me.
Its great fun when someone leaves a computer lying around to set the depth alarms and time alarms to something like 5m and 5 mins so they get all confused on the next dive when it starts going beserk.
ppO2 alarms for minimum possible are fun too.

I tried using audible alarms but found I knew the pressure remaining before the alarm told me. So they became just annoying reminders of what I already knew. It felt like, approaching a red light, slowing down then having the passenger say, "The light is red."

I once forgot to change the gas settings on my computer for a dive to 240 fsw ... the computer thought I was doing the entire dive (including deco) on EAN32.
The X1 gives you some interesting displays when it thinks you've done bad things to yourself ... but I found myself very glad that the audible alarms were turned off ... could've proven majorly distracting ...

Interesting. I have gotten into the habit of timing my computer checks. Like keeping pace during a marathon, I try to keep track in my head. When I check my gauge I have a rough idea of what it should read. If I'm off a little I check my depth or try to be more aware of time as it passes. Whenever I check my gauge and it differs significant from my expectation my first thought is that I am narc'd (which so far has been the correct thought). I then try to check my gauges what feels like twice as often as I normally would, which happens to work out to as often as I actually do check my gauges.
I won't use an air integrated computer for several reasons. Potential failure of the electronics and transmission, cost, and the fact that my hearing often does not detect alarms from my regular computers.
A good diver will check their SPG with reasonable frequency. Yes, I know... there are enough divers out there who don't. That's why the Darwin Awards were invented.

My Nitek Duo would on occasion spontaneously change my gas mix for reasons I never could explain. I dive strictly air so I wasn't changing anything. Several times it switched me to 50% or higher O-2. Of course I dive with two computers since according to that one I was dead on several dives!
He would make a great EU Commissioner! When they put a question to "democratic" vote they simply throw the question back time after time until by attrition they get the answer they wanted all the time.
