so the first is the technical screen. Top row is fixed with depth, *you get to choose between fresh/salt/EN*. EN is the "average" of the two, this selection only changes the accuracy of the number, but does not change your decompression obligation. Will show the ascent graph next to it when you are ascending, but goes away otherwise. Your bottom time *the line under the time goes in 15 second chunks so you can see seconds*, the battery gauge, and deco stop depth/time depending on where you are. Shows the surface interval if you're at the surface.
Center row changes depending on what is going on. Will either show your current PO2 if on OC, or your CC setpoints in the middle. The two open spots can show Max Depth, Avg Depth, @+5 *super useful to show your Time to Surface if you stay where you are for another 5 minutes*, deco ceilings, GF99 *your current tissue loading*, CNS clock, Time of Day, Dive End Time *in time of day not duration*, mini compass, Dil PPO2 and FiO2 for CCR. Mine has average depth and time of day most of the time. All of the other info is available during the dive, just not on the front screen.
Bottom row shows what mode you are in, what gas you are breathing, your NDL, and your TTS. Super nice.
Second picture is recreational nitrox mode shows your current depth in big ass numbers in the top left with your dive time in minutes and seconds below it. To the right is the decompression section where safety stops, deco stops, NDL's, and your nitrogen loading graph are shown. Bottom section is again configured by the user where you see what gas you are breathing, and then TTS, CNS Clock, PPO2, MOD, temp, time, Max depth, temp and time, PPO2 and CNS, or Max and Avg depths. You get to choose. One button clicks over to the other screens where all of the rest of the info is easily available, gas switches are two button presses since it automatically goes to the best gas for your current depth, etc etc.
