Another wireless transmitter mounting question...

    I've been diving with AI soon after they came out and I could afford it; I think it was in the early 1990. Never had a transmitter failure. I had one computer failure at depth where while I was around 50 feet, the sensor went bad and said I was @ 165 feet and need go up immediately. I did not go up as I had spg.

    But because I was doing multilevel multiway diving, I sat out for 24 hours then resumed the diving. I learned to have 2 computers when I go away and spend lots of money getting there.

    Hope this experience help someone who might be justifying getting 2 computers.

    I try to use AI as generic transmitter based pressure gauges, and WAI for wireless in particular. Unfortunately the AI computers were usually worse than the WAI ones. I would actually have 0 issues using one on the hose itself for backmount diving, but no one seems to be trying to sort that kind of computer out. I'm also frankly surprised that with the Shearwater DiveCAN out that more rebreathers aren't fitting transmitters into the heads for the onboard bottles. I think X-CCR is the only one currently doing it. Certainly not the first, but I think it's the only current one

    Do you really mind explaining that?

    I know you aren't asking me, but your post made no sense. I missed it the first time through but when the other member posted about your ignorance in regard to AI computers I went back and read it.

    AI computers whether wireless or hose take all the information that is necessary to determine the limits of a dive and turn it into a very useful and very accurate "dive time remaining" value which updates "on the fly" and provides the remaining bottom time based on the most limiting of 3 factors- NDL, P02, and gas remaining. It is certainly not "fluff" as you described it.

    I dive my Perdix AI on my left wrist and my transmitter comes off to my right. I've never had a single issue with the Perdix AI staying connected to the transmitter.

    Why. Why carry an spg with an A.I. dive computer? You get to take off a hose for less clutter less weight more streamlining, less to think about. easier for travel. If it ever happened when your dive computer dies you go to surface screw in a short 2 ft hose tiny spg and attach at shoulder. Itll be in your save a dive kit. You will already have a cheap backup computer like a zoop or whatever thats been attached to your bcd or wrist. We already do that to not have to sit out 24 hours.

    There is zero need for an spg in rec diving if you have air integration. In fact go the next step and get rid of the octo and go SS1 or Air2. I have 2 hoses not 4. Ridiculously streamlined. Super light reg set up. awesome for travel.

    1- A mini spg is about the size of a half dollar and is often on a very thin hose. Tucked behind the BCD you don't even know it's there.
    2- No need to abort a dive in case of the primary computer failure
    3- Much easier pre-dive gas check no need to wait for the AI computer to get to the right menu and sync with the tank to do the pressure check, it's a quick glance at the needle.
    4- If necessary a buddy can check your spg sometimes more conveniently then on the wrist

    I have an Air 2 and a 2+1 hose rig, the 1 hose of course being the extra thin SPG hose.

    I dived the 2 hose no spg system for years. After 2 AI computer failures over the past 10 years I prefer the redundancy. In fact I dive with not 1 but 2 identical AI computers (wrist, retractor in pocket) AND a mini spg.

    I have the same tiny spg on the tiny hose. It stays in my save a dive kit. so you may lose five minutes of a dive surfacing. You gain losing another hose..... there is no reason to have an spg. really. There is however many many reasons to carry a pony tank but an spg with A.I.? Thats just excessive as there is no danger not running an spg.

    This is one of those things that's simply of diver preference. I don't mind the extra hose in exchange for not having to risk interupting or aborting a dive- if you're at 100' you're not going to surface and lose 5 minutes, the dive is probably over. Plus the other advantages I wrote in my post.

    true, we all have different priorities and I believe everyone should dive with whatever equipment they want. ponys included
