What's the difference between these. It's supposed to be in P-mode to do quickshots, but it only says GPS.

I believe it's P for Position ( or is is Precision ?) mode and S for sport mode.

If you're not in sport mode then just assume you're in P mode.  P-GPS, P-OPTI, P-ATTI

I didn't seen any on-screen indication of "P-GPS" on the HUD or UI so I understand where you're coming from.

Thanks! I thought I was going crazy. All I see is GPS. I guess it's just a legacy thing in the Spark video.
