Wondering if anyone can recommend a mechanical map measurer that is currently available to purchase. ( I have a new found need for this arcane practise.
)
The device Im after is a hand held unit which has a small trundle wheel than you run around your map route, and the distance is given on a dial. The dial generally has scales to suit the map. I did have a plastic Silva one 20 years ago which i was not that keen on. (seemed cheap with a somewhat wonky trundle wheel) .
ive seen metal ones which were more precisely made which i would prefer. Any ideas?

A piece of string?
Seriously, I've used both (back with the dinosaurs) and the string worked better for me

A piece of string...
That is what I used the other day when my wife wanted to know how long was our morning walk. (13 KM)
But it would not be all that accurate.

Search for "Silva Map Measurer Plus site:au". Make sure you're sitting down when you see the price.
Note that I often use Google Maps for this purpose (moving the suggested route to match the actual route I plan on taking).

You could use a compass, the circle drawing kind, just measure out the cms.

Create a GPX route on a website like gpsies.com, and see how many km it is. Sites like gpsies.com can follow mapped tracks so you don't need to click on every wiggle.

Thanks for all the suggestions. I have found a nice vintage Swiss made unit . Apparently they're called Opisometers. I do like Google Earth for this kind of work- especially as you can get an elevation profile- but in this case I am working off paper maps.
