When the Military Map protractor is rectangular, it is less consistent to run the string.

To do this, we run a string from the center of the UTM Grid Reader to the point on the map, and then check the edge of the tool for the direction we can use on the compass. We will often run 2 maps, a small 1:24000 map for more of an overview, and a 1:12000 map for double the detail, and so having both slot tools on a single UTM Grid Reader or Military Map protractor is a huge benefit.įinally we often use the tool to check or get an azimuth or direction reading. We wanted a 1:12000 grid slot tool, but they are extremely rare to find, and we tried using a corner marking tool, but they are not nearly as easy to use as the slot tools. The slot tools feature a slot along the vertical axis which make marking a point super quick and they are easy to read. We struggled to find the best tool since most UTM Grid Readers we prefer (also called slot tools) use a 1:24000 grid. See the other pictures for more information.

In the main picture (a digital prototype), the pink/red is actually white around the outside edge (in the real life tool), and the slot cut lines are displayed as red lines. However we have been running a larger set of maps using a 1:12,000 scale so we can see more detail. The provided maps are 1:24,000 scale on a UTM grid. The main focus of this event is land navigation. Since 2016 Bison Tactical has participated in a 24-48 hour land navigation race called the Sniper Adventure Challenge. This is the Bison Tactical custom UTM Grid Reader. UTM Grid Reader | Military Map Protractor
