Product Description

This is a large UTM Mini Corner style tool intended for use in a classroom teaching situation. It is about 4 times the size of our regular tools. That means you can hold it up to the whiteboard to demonstrate how to use it, and you students can see it.

You can easily mark a grid on the whiteboard for your demo map. Just use the tool to measure out and mark the corners with a dot. Do as many grids as you want, and then connect the dots with a straight edge and your whiteboard marker. Add some grid coordinate labels and you are ready to demo UTM coordinates.

The actual scale of the tool works out to 1:6,369. Use that scale if you want to create a map image for printing on a large sheet of paper to use with the tool, using a service like to create your pdf file. If you want to enlarge part of a 1:24,000 scale map, enlarge it by 377%. (24000 / 6369 * 100)

We use the same scale for our UTM Grid style classroom training aid, so it’s easy to move students from the conceptually simple idea of the grid tool that just fits inside the grid, to the more complicated, but more precise, measurements they can make with a mini corner style tool.

There is also a hole in the corner that you can use to hand the tool from a nail or peg, to keep it handy. I put a self adhesive backed hook on the edge on my whiteboard to hang my training aids from.
