Oh, I gave the compass to Keith Lober, the brilliant Team Leader of Yosemite Search & Rescue, after working with him as he collected compasses. Refining this innovative invention, I developed the GRT. The compass capsule was mounted on a Perspex plate that had orienting lines etched into it AND lines running perpendicular which they use to determine their grid reference from the map. The crew’s makeshift assembled these for use in the bocage of Normandy, which presented a unique theatre for armoured close quarter combat as distant features could not be seen to resect in determining their exact location, instead they micronavigated. In researching the history of these compasses, I corresponded with a WWII German tank commander, Oberscharführer Ernst Barkmann, who completely unexpectedly sent me his military compass. Firstly, thank you for your review and yes, a great idea to put it on your baseplate compass lanyard. Comes with a hole to enable a lanyard to be attached.ĭavid this is a long answer to how the GRT came into existence.Ruler edges are marked in actual map distance – no fussy calculations required, easy and precise.1:50000 & 1:25000 scales colour coordinated to avoid confusion.Romer scales numbered to prevent mistakes.Rounded corners to prevent snagging and holes in the pocket!.Extended grid lines make sure you correctly align the tool on the map so you don’t make a mistake, even in bad weather.Accurately plot and give 6 & 8 figure grid references on 1:25000 scale maps.Accurately plot and give grid 6 figure grid references on 1:50000 scale maps.Ideal for both Search and Rescue professionals and outdoor enthusiasts. Ideal for GPS users – accurately project and plot waypoints. Take the guess work out of grid references – accurately give and plot 6 and 8 figure grid references with confidence, and accurately measure travel distance.
How many times have you received an inaccurate grid reference, or made a mistake plotting one using a compass roamer? Need to Navigate? Then you Need one of these! The Pocket 1:25000 or 1:50000 Grid Reference Tool Map Romer Scale
