Wondering is anyone out there has the Oceanic Geo computer and if so how do you use the thing? I have read and re read the manual, installed the cd and downloaded the stuff to my computer and re read the manual again. It seems that without actually going for a dive I can only play with the watch, stop watch, alarm, ect. The book tells me to go into dive mode and then depress x & x button to bring up settings yada yada. Just cant figure it out. Do I just have to jump in the water to get it to work?
