Had my smart com SOS on me. It told me to do a safety stop at 10' for 2 minutes. This was a 40 minute dive with the deepest depth 70'. It gave me the safety stop info after I was 5' from the surface, which I didn't notice the warning at that time, so it SOS. I downloaded my dive to reveiw it and that's how I confirmed the info above. When I go into Smarttrak to change computer settings it will only get the settings, not allow changes and theres an SOS check box at top that I cant change. It's been 36 hours since it locked. Thanks for any input.
