Hi Karl,
Wow that got my attention! Could you elaborate a little more on this feature? I dont understand how a graph can help you do deco

Why not?
That's what you're doing when you run a profile on a computer topside. You're looking for a specific tissue loading profile before you deem it "safe" to exit the water.
The VR3 lets you see what its model is doing and where you are (according to the model) at all times, if you want. The tissue graph makes this possible, and as far as I know, its the only dive computer with that feature.
The "dynamic" view of how the model is perceiving your body's inert gas load is, IMHO, quite valuable underwater. You quickly learn what sorts of profiles produce what sort of (theoretical) tissue loads, and what behavior affects it - and how.
Have/do you dive a VR3?
