Yes, I ran all three devices (Subsurface-mobile, Companion app, 
independent GPS) simultaneously. I wish to do a wider inspection of the 
coordinates for the other dives on that trip, but at this stage I cannot 
scroll down to the start of the previous day's dives because 
Subsurface-mobile FREEZES before I can scroll so far down the list. It's 
a time consuming process but probably worth it to check whether there 
are other similar cases. The error is close to one geographical minute 
in both directions, using the companion app and the GPS as a yardstick 
that have positions at 11:33 and 11:34 respectively, compared to the 
11:30 measurement by Subsurface-mobile. Perhaps a rounding error in 
converting degrees to minutes?

Would it be possible to perhaps pull my coordinates from the server and 
email these to me? This will allow me to get to the data for the other 
Kind regards,
