PAUL D it functions sufficiently as a standard compass. main reason for purchase was to replace damaged unit for pro plus computer. it also helps protect computer P D

DENNIS V I believe it should work. Go to Oceanics site. They have all the compatabilities.

KIRK K I was in a similar buying/shopping situation a while back. I am not 100% sure that your anticipated compass perfectly fits the regualator that you have. But I think that it does. So why not buy the compass and if it does not go into place perfectly return it as the "wrong" size. There is a curve ball in fitting it together but once you figure it out, it was easy and is attached very well.

PHILLIP C If the compass is for the same model computer - pro plus 2.1 then yes. the compass replaces the top handle - as i recall it does come with instructions. If not it replaces the top handle - with the compass in your hand any screws / attachments should be obvious.

Brett H The datamax was the original computer in this series many years ago. Recently the pro plus 2 was updated to the 2.1, with this update they added increased memory to log dive data with, made the computer firmware upgradable, and gave the computer data retention during a battery change so you won't loose decompression data if you have to swap the battery.

CAROL M Yes it will. We bought a pro plus II for my son and bought the compass to put on it. I was lucky that I had bought the computer and compass from the same person and they installed it for me. But I believe its not hard to install at all. Good Luck

TIM S I purchased a replacement compass for my Oceanic and it fit perfectly.

WALLACE W As far as I know, I have the most recent pro plus II, and the compass fits fine.

JERRY B It should. The difference from the pro and pro 2 was the display screen.

LeisurePro S Yes, this will fit the pro plus.

LeisurePro S No, the Oceanic compass won't fit on the Atmos AI. Here is the compass that will fit on your computer.
