I have about 20 dives and I find myself constantly looking at my wrist mount computer for depth and time. I also find myself fumbling for my console to check my air ALL THE TIME. So I wonder if an AI computer should have been the way I went from the start? If I had everything all in one spot on my wrist i might be able to stay more neutral and relaxed?
Three thoughts: 1) A wrist-mounted, wireless AI computer IS a convenience. If you are comfortably swimming in a neutral, horizontal position, hands lightly touching / joined together in front of you, you can easily read depth, time AND air supply with at most a slight rotation of the wrist. The system, considerng both the computer and transmitter, is not inexpensive but worth it if resources are available to purchase it, new or used (and there are good buys to be had on eBay and elsewhere from time to time). I use a Vytec and transmitter this way, even when diving doubles with deco bottles, and I love it; 2) I would not recommend
replacing your SPG with a wireless AI computer and transmitter. The actual streamlining benefit - removing a hose - is relatively trivial. And, although experinces differ, there may be instances where the units fail to synchronize, or where readings become anomalous (usually at lower tank pressures) during a dive. Why take the chance, when keeping a SPG (which you already have) is really not a problem?; 3) based on your description, I would encourage you to continue to work to develop good buoyancy and trim, and to practice using your SPG while maintaining that buoyancy and trim. (I didn't read anything in your post that suggests you are trying to substitute equipment for experience, but just want to add emphasis to a good point made by another poster).
I understand your comment about being relaxed, and was there this weekend. Diving deep (to the props on the Oriskany), with an AL80 and AL40 both clipped on the left side, a bungee strap broke on my Vytec mount as I entered the water. I took the Vytec off and put it in my pocket to avoid losing it (it is a back-up computer on deco dives, anyway). But, I then seemed to fumble a couple of times with my SPG when reclipping it. It was a minor issue, but still a distraction, and I probably sucked a bit more air getting frustrated with my inability to easily do something - unclipping and reclipping the SPG - that I usually do without even thinking, at a time when I particularly didn't want distractions, or any additional burden on my gas supply. My assessment afterward - I still really like the convenience of wireless AI, but want to avoid becoming too comfortable / dependant on it.
