Well, another weekend, and another day in the pool. There's definitely something going on with the software in the computer. If I go into side mount or gauge mode, it will give me tank pressures, GTR, etc. Switching to Open Circuit, I get nothing. When in open circuit mode, I can go in and select the transmitter, and it will show me "Good battery" and the tank pressure, but exiting back to the dive screen, it just shows the gas mix, no pressures, no GTR, etc. I dove with it again today, and other than this huge issue, I really like it. I'm working on my side mount right now, so that's how I've been diving, but only with 1 tank. I opened a ticket with Apeks support when I got home, so I'll update the thread when I hear back form them.I don't see how it could be user error (not ruling it out though), since it will show me the tank pressure when I select the transmitter, but on the dive screen, only shows the mixture. Sat on the pool deck and went through the manual, and it should show the tank pressure to the right of the gas mixture. Photos attach.
