We're fortunate enough where I work in the Middle East to have both a lat/long cursor readout on our screens and an instant replay facility for any land line and air/ground comms. You can't believe how handy that is in an area of the world where English is not the primary language spoken by most of our customers and comms can be scratchy a lot of the time. I'm surprised that major units everywhere don't have instant replay. We use it a lot.
