Recently I found myself 2 days before a hike without a map ruler for 1:24000 scale maps. I didn’t know of any retailers locally that would have what I needed and I didn’t think that an online retailer would be able to get the ruler to me in time for the hike. Sure, I could get by by just using the scale on the map, but those are often scaled in miles and I prefer to have the option to measure things out in yards or meters if possible.
MapTools.com to the rescue! I was already on their site to order some other tools (which will be reviewed in an upcoming article) when I noticed that MapTools.com has a free download section. They have a ton of great tools in .PDF format that can be downloaded for free. I downloaded a 1:24K map ruler and had several printed on overhead transperancy sheets at a local office supply chain. You may also want to consider laminating your ruler since the printing may rub a bit under field conditions. The rulers worked perfectly and I was able to share some spares with others on the hike.
