I have a list of Perdix AI "updates" that I wish Shearwater would implement. This weekend, my list grew by one item. I decided to post my whole wish list here and see how many people want the same things. Maybe if enough people voice support, Shearwater will implement at least some of these things. Starting with my new item first.
1) Change the display settings for the middle row (OC Tec mode) to allow more than just ppO2. Specifically, I would like to be able to display T1 and T2 tank pressures AND also have a Timer. As it is, the center field in the middle row only allows ppO2 or nothing. So, in sidemount, I have to decide whether I'd rather see both tank pressures OR have a timer replacing one of the tank pressure fields.
2) Change the GTR function to reflect ALL the time required for an ascent and any stops that the computer will prompt for. Including if you go into deco. IMO, it's fine to calculate GTR assuming the diver will only use the Active gas and based on the SAC measured on any/all transmitters that are currently enabled. My Oceanic AI computer calculates GTR to include any and all stops that will be prompted for. I don't see why my Perdix AI cannot do the same.
It would certainly seem fine to me if GTR was limited so that it is only displayed when there is exactly 1 gas Enabled. I.e. if I have a deco gas marked as Enabled (not necessarily Active), then GTR doesn't display at all, ever.
3) Add another setting for what transmitter is displayed. That setting would be something like T Active. When that setting is selected for display, the Perdix would display T1 pressure if the first gas in the gas list is Active. It would display T2 pressure if the second gas in the gas list is Active. That would allow the diver to have a transmitter on each gas to be used during a dive and only have to display 1 tank pressure on the screen, and the tank pressure displayed would automatically be whichever one corresponds to the gas currently being breathed.
If you install transmitters on 1st stage and leave them there, and you always use the same 1st stage for your back gas, the same 1st stage for your lean deco gas, and the same 1st stage for your rich deco gas, then you would just have to configure your computer one time and it would then always be correct. You would only ever need to edit your gas list to set the gas mixes for each gas.
This would require a programming change to the gas list, as it currently shows them in order from richest to leanest. You would need to be able to have Gas 1 remain as the first gas in the list, even if it was not the richest gas in the list.
4) Give me some way to have my current Gradient Factors setting displayed on the main screen. I don't change my GF often, but it's something I should check on every dive. Having it on the main screen, so I am reminded of what it is without having to remember to check and then press buttons would definitely be more useful to me than, for example, having my current ppO2 displayed. I'm diving OC. I select my gas based on my planned max depth and ppO2 preferences. I know I am "safe" before I get in the water and don't need to see it displayed once I'm in the water.
5) Update the onboard dive log to let me see Start and End tank pressures for all configured transmitters. Also, show the measured SAC.
6) Let me configure a tank size (in cu-ft or liters) for each transmitter. Let me choose RMV for display, as an alternative to SAC. (This one is definitely low priority for me, but I have seen other posts wishing for this)
7) Let me choose 30' (or 9m) as my last stop depth. It's really common at least among my circle of tech divers, to use EAN80 as a final deco gas, in order to stay down out of surface chop. It would be nice if my TTS display reflected that.
Anybody else have anything to add to the wish list? Think any of my wishes should be changed to be of more benefit to more people?
If you think the Perdix AI is already perfect and cannot be improved in any way, there really is no need to comment at all.
