Exactly.There should be a 4th option for Sidemount.
Ok, thanks. Thought so but was confused.Correction, Dive Log has a sidemount mode and does average litres per min calcs, the Perdix itself does SAC and GTR calculations from one TX or the other.
sac is consumption rate. gtr is how much time you have to reach your designated onboard pressure. IE you are set to be on board with 500 psi ad you have 750# YOU ARE AT 100 FT AND THE COMPUTER SAYS AT 50 psi a min you have 5 minutes. if you went up to 30 ft the time would change to 10 minutes because the consumption rate would be less. TTS is different in that it is (either) the time it will take to go to the surface at designated ascent rates or the time till you have to start your ascent. I dont remember which for sure. Its been a long time since i have used an AI computer.So, does the Perdix not calculate SAC rate?
I'm a little confused on the difference between SAC rate and GTR.
FYI from SW:
"The GTR calculations on the Perdix AI are only for single-tank diving that does not require decompression stops.
