Depends on your diving but an integrated computer that monitors your PP02 can save a bit of deco time and if covers screw ups as well. Like forgetting to change the set point, (not that i would ever do such a silly thing

)
What ever you chose you will need another computer to back up the primary so I chose one inboard and one off board on my classic.
This became irritating because the inboard was always clearing before the off board but now I have (or will when i get the cable sorted) my back up inboard as well. When i need it for OC I just unplug it from the unit and use it.
I was using two VR3's now i have a Hamerhead primary controller with on board deco and a Sherewater plumbed in as back up.
