A few years later these fancy electronic calculators came in and I said, "But what happens when the batteries go flat". Well, I found you can carry spare batteries and you get greater accuracy than the 3 figure accuracy of the slide rule. I still own a slide rule and keep it on my desk, but it's not my primary method of calculation any more.
I did orienteering for many years so I know how to navigate off track using only a map and compass. But my GPS not only has map, it also has a little marker showing "You are here". Why wouldn't I use it as my primary method of navigation? I have a huge collection of paper maps that are ideal for planning trips back at home, but they are never my primary method of navigation.
I still carry paper maps and a compass, but I never use them while bushwalking, they just stay in my pack like the first aid kit and PLB. It's a good idea to carry them but you hope you never need to use them. It's true that GPS batteries can go flat or you may fall over and smash your phone on a rock. But I have seen people fall over and smash their compass, or their maps get soaked in rain and become unreadable. So you need a backup for any system, but why use a map as your primary method when it doesn't have a You Are Here marker on it.

Using map to ground skills (checked with bearings) to interpret the features on the map with what your seeing on the ground is the most important part of navigation imo. It's not just where you are but where you have been and where your going.

As some people no doubt said when printed maps first became a thing: "If you're using a map, you lose the valuable knowledge of the terrain: having to learn where the watersheds are, how the tributaries flow, where the ridges meet, how there's more moss on the south side of the tree trunks, where the rock changes to granite..."
But it's like that for every new tool - it multiplies your abilities, at the expense of disconnecting you a little more from reality. I navigate by GPS now and I'm not going back to compass and paper. But every now and then, just for the challenge of it, I leave my map and phone at the bottom of my pack and navigate using just the land. A few years ago I discovered that I could get from Kanangra to Katoomba without consulting a map or phone. Similarly I can get from Wog Wog to Yadboro without a map, or from Bell to Dumbano Creek. Technology-free navigation is very satisfying (I consider a printed map to be technology too), but I wouldn't want to have to do it that way every time.

I don't mind getting "lost". In fact I quite like it but there are limits to lostness.Mechanic-AL wrote:crollsurf wrote:Haven't carried maps in years.
No Map....not even as a back up?? WOW![]()

The well worn track and the odd sign post definitely doesn't hurt either!
