How Do Shearwater Work Out SAC Rates? #askmark #shearwater

Updated Gear Affiliate: https://divernet.com/go/youtube-affil... Visit Shearwater.com: https://www.scubadivermag.com/affilia... @sebastienschaer8111 #askmark would it be possible to explain how the SAC rate is calculated in the shearwater? It seems different that the SAC rate calculation that you can find in internet. I also know that everybody is different and the condition also affect this consumption , but what value would be a average SAC rate vs a good SAC rate? @leemiller358 #askmark - 4 dives on my Perdix 2 and loving the AI and the easy to read screen and functionality. Here's another question on SAC rate. Perdix is telling me my average SAC is 20.4 psi/min. My introductory understanding is if I want to convert to cubic feet/min (RMV - using DAN's definition) I would need to factor in tank volume and working pressure. Does Perdix allow for this? I have two tanks I routinely use that are slightly different. I don't see where I can enter "Tank 1- 100 cu ft, 3445 psi" and Tank 2- 100 cu ft, 3144 psi" in the computer. Shearwater associates the AI serial number to the tank to support up to 4 transmitters. How about managing multiple tanks with one transmitter.
