6stings A2OC Donor 17 Feb 2016 #1 Some tunnels here go deep under sea level, the deepest today was 220m. The GPS shows the level above and below the sea, but it lost the satelite connection at some point in that deep tunnel and didn't stop counting down until I exited the tunnel Last edited: 17 Feb 2016
