I like the idea of tablets etc in an appliance - a great resources. However, at Sampson Flat, strike teams were sent to s specific location. My appliance got the map book out, and navigated to where we had to go.
Other appliances had to ask for directions, as they only had a tablet (no map book) and either it was too hard to work it out, or they had no service (which was a distinct possibility)
