I also use the 1x1 degree grid search system (marking the corners if not using UOAutomap or UOC, or just standing on one of the corners and starting to dig to the front of me and to the side every 4 steps, walking the grid as if mowing a lawn).
But, Malee, Dizzy - it's not as simple as that for those that might think the map pictures are somehow definitive. The DL Coordinates are right, but for some of us the spot depicted on the map can be off by a screenwidth or more - especially in CC.
In the two cases below, the pin is shown completely on one side of a physical barrier, but the chest ends up being on the other side (to the right, in every case). I run into the pin displacement issue every so often, but about 1 in 100 maps it's truly amazing (and these are just two of the incidents - I had multiples in the Hedge Maze (with the pin completely out of it), at the river NE of Vesper, and along the river between Britain and Trinsic, that I never remembered to make screencaps of).
This one had the only part of the pin crossing the water near the "pushball" end, while the chest was across the water on the pointy end. This was before the recent changes, by several years.
This one is a map from last week, where the pin shows completely on the west/left side of the ridge (Where there is maybe a 1-2 step wide strip in the proper latitude and longitude), when the map was on the east/right side, and somewhat further south than the pin seems to extend.
In BOTH cases the locker coordinates were right - the MAP depiction in CC was wrong. I even had one on Moonglow, almost a decade ago before the Davies Locker existed, that was on the East Road (toward the Telescope and the Illusionist guild, but before those roads split) that seemed to be almost 2 screen widths closer to the city fence than where the chest actually was found (directly north of that intersection where the road split).
