Long time Petrel 2, got a Perdix AI and Swift for Christmas. So diving both computers for the time being while I get the Perdix set up the way I want it. When I open my tank valve, the Swift indicator lights up green. Perdix set up with Swift serial number and syncs up. Swift is on a 6" miflex hose (with HP spool). When I descend, my Perdix reads tank pressure. Then it loses comms with the Swift. And when I ascend to the shallows (recreational dives < 50 ft), such as for safety stop, my Perdix gets tank pressure readings again. This has now happened on multiple dives. Only about 5-6 dives on both the Perdix AI and the Swift. Any ideas what the problem could be, if something obvious, or do I need to contact Shearwater and possibly send things in?
