I enjoyed this hugely. My wife and I have used the ordnance survey app for many years now. In the benign Welsh Marches it is great. The consequence of failure is minor. No cliffs to fall off if the weather comes in, no Grimpen Mire to be swallowed by. Nonetheless, we always have a power pack and lead in case one gets delayed and battery runs out. If we were going up to Snowdonia we would ensure we had a paper copy… just as we have other safety kit.

Years ago i dived in Malaysia. I always had a klaxon in BCD airline. Less experienced divers would ask ‘do I need one of those’. Maybe, I would reply. And I did. I dived with an instructor. It seemed benign but as we went down we realised a huge current was running along the bottom. We tried to get behind the shelter of a coral (that works, like a rock in a gale). But we couldn’t make it and we abandoned the dive. We did our safety stop and when we surfaced we were half a mile from the boat. The instructor put up a marker but the boat failed to respond. I blasted. It took three goes. A few days later two divers were in the sea two days because the boat couldn’t find them.

So we take care walking, but we use an app all the time and it’s brilliant.

A little note on ice-steps. My son climbed a 6000m summit in the summer. Last 300m 45 degrees took 3 hours in crampons, hammering in breathes with every step. I bet he was glad not to cut steps!

I'm so glad I came across this wonderful read! Little did I know, as an elementary school student visiting the USGS headquarters on our annual field trips there, that I’d one day be working in the world of maps and mapping apps once I moved to the UK. I’ll admit I’m heavily biased toward Harvey Maps, possibly as they feel most familiar in style to the USGS maps, though I would argue Harvey's are far superior!
