My much used German made map measurer

Map measurers

Map measurer, opisometer, curvimetre, mile-o-graph, meilograph, chartometer, call them what you will, in the era of digital mapping, who uses such an antique analogue object today? Well, Three Points of the Compass still does. I have used a simple little map measure for decades. The  cheaply made one shown above, made in Western Germany,  has been pulled down off the bookshelf hundreds of times over the past twenty years when planning routes. It replaced another that gave equally lengthy service but had eventually died the death.

It never goes on actual walks with me. Though I am one of a seemingly dying breed who still likes, appreciates and takes hard copy maps with me on trail. If I want to measure a distance on the map while sitting in a tent, pub or hostel lounge, I either guesstimate, infrequently use a roamer scale on my compass baseplate, a strip of paper which is then measured against the scale at the bottom of my map, or, most frequently, I use a length of thin cordage. The small hank of 2mm yellow cord in the image below is one of the two I carry for attaching my Katabatic Palisade quilt to my sleeping pad.

Map measurers can be sweet little pocket watch style affairs that were tucked into the waistcoats of the gentry, or simple little wheeled opisometers, like the one below,  sold in the likes of Stanfords map shop in the mid-twentieth century.

They could be made of plastic, bakelite or metal. Have handles incorporating bone or ivory. Cheap versions were given away at petrol stations, or combined into all-singing all-dancing measurer/compass/thermometers made in China by the thousand. That said, they still work. The cheapest will do the same job as the most expensive gold plated measurer ever made. They even make incredibly expensive digital versions today. I look on them with dismay, much preferring my little analogue measurers.

The idea of map measurers is an old one, probably as old as ‘to scale’ maps themselves. Beyond simple calipers, early map measurers, or opisometers were very simple affairs indeed, little wheels on a threaded bar that could be pushed along a line. More expensive designs that incorporated a dial scale didn’t really appear in any great numbers until the later nineteenth century.

Anyone that required a map was also using a map measurer. The military use them, sailors use them, motorists use them, town planners and draughtsmen use them, and still, just a few walkers use them. You run a little wheel along a route, a path, a road, a river, a line on a drawing, then either read off the result or measure against a standard.

While a piece of cord or length of paper will simply measure a length, more complicated versions can measure in many units- multiples or sub-units of inches or feet, centimetres or metres, versts, miles or kilometres. Also to different scales- The two-faced French made measurer below has scales for 1:20 000, 1:25 000, 1:40 000, 1:50 000, 1:75 000, 1:80 000, 1:100 000 and 1:200 000. Made almost a century ago, it is still an effective and useful piece of kit that cost me less than a tenner. Not that I ever use it of course, I still pull down the old favourite from the bookshelf.

Along with thousands of other hikers I rely very much on my online O.S. Maps when planning my routes. This will give me not only distance but also daily elevation. However I still like to use a map measurer on my paper maps when I can. It forces me to look at the terrain, the twists and turns, the type of country being crossed- across bogs, through woods, traversing moorland, traipsing through the backstreets of towns.

I won’t go in to any great detail on map measurers here. There is an expanding page on my website that gives more information. Over the years I seem to have built a bit of a collection of these little devices, just a small handful of which are shown above. There seems to be a dearth of information on these online or in print form. Perhaps it is because they aren’t that interesting, just to the likes of me and one or two other like-minded souls. So I have decided to share just a few from my collection with you- good reader, over the next year. Twelve, one a month, beginning January. I bet you cannot wait…

Making a final choice…

Though fiddly, and occasional needing an extra bite, the small bottle opener on the Squirt S4 will do just that

Over the past few days I have been looking at the various little multi-tools that Leatherman have released over the years with the aim of seeing which is most suited for taking hiking.

As you can see from the tool table below, a wide variety of capability is provided by these little multi-tools. However for Three Points of the Compass, the E4 is just about useless on trail whereas almost any of the remaining eight, shown above, would be a great partner.

The lack of any scissors on the Squirt P4 also precludes this tool from any gear list I would compile. I can see how many hikers would pick the Micra or Style PS from this line up. Certainly the latter accompanies me as part of my Urban EDC to work each day. Inclusion of a pair of pliers would be a nice feature on trail however I prefer a full size pair of scissors over pliers which narrows my choice to just three: the Micra, Squirt S4 and Style CS. All three have a similar blade. So it comes down to what other features are included and all three in my shortlist have similar extra tools. While I have a pair of tweezers in my First Aid Kit, I still prefer removable tweezers over those fixed to a multi-tool such as the Micra and those in the Squirt S4 (and E4) are conveniently tucked away yet easily removed.

The useful detachable tweezers on the Squirt E4 and S4 tuck away into the tool efficiently and could easily be missed if you were not aware they were present. They are easily extracted, unlike some of the alternatives

I like the extra medium sized screwdriver on the Micra and S4 though I do wish it were an awl instead. If it were exchanged for an awl that would remove my often used bottle opener. I prefer the dedicated thin eye-glass screwdriver over using the less convenient flat Phillips tip. However the Style CS offers a small but useful toolset, is the thinnest of the Leatherman keychain multi-tools and weighs less. The lightest Micra is 49.9g, Squirt S4 is 52.3g while the Style CS (still available for purchase by the way) is the lightest at 41.7g.

Still looking good after thousands of trail miles, the Leatherman S4 remains a favourite for Three Points of the Compass

My biggest preference other than my essential two tools is the ease in opening tools from the outside with no need to unfold the entire multi-tool. So, for me, it narrowed down to the old, now discontinued, Squirt S4.

Carried in my ditty bag, one of these great little multi-tools has accompanied Three Points of the Compass on well over 3000 trail miles over the years. While I do occasionally swap it out for a different knife or multi-tool, seeing if something else works for me better (usually trying a 58mm Victorinox or Leatherman Style CS), I constantly find myself returning to the old favourite S4. Perhaps I need to find a spare on the second-hand market in case mine should ever get lost on trail somewhere. If only it also had a can opener and that awl…

While you may not choose to carry one of the small Leatherman multi-tools as part of your hiking gear, they make great EDC items. Whichever you may purchase, one of the X-small leather Heritage sheaths produced by Leatherman to celebrate their 35th birthday in 2018 makes a great holder

Three Points of the Compass has looked at quite a few knives and multi-tools that may, or may not, be suitable for backpacking, day treks or Every Day Carry. Links to these can be found here.
