Rated 5 out of 5 by from Plot EXACT positions on a map I first learned how to use one of these UTM grid readers back in 2001. It took less than 5 minutes to master and ever since, I've avoided lat/lon like the plague. Think about it... lat/lon is the system Columbus used. But now it's the 21st century. Assumng you understand what the term "datum" means, the UTM system is EASY, FAST, and ACCURATE. Learn to use this; you won't regret it.

Rated 5 out of 5 by from excellent piece of kit An excellent, inexpensive plotting tool. With this simple piece of plastic, a compass, and either some good deductive reckoning or a GPS, you should never get lost, and should always be able to find your way. It is so good that I am getting a second one so I'll never be without.

Rated 4 out of 5 by from Probably very useful. TERRIBLE manual. A simple one page of info provides minimal info, and provides a physical address, to which you can send snail mail, to request "The Universal Transverse Mercator Grid, a USGS fact sheet". I found that document online, in PDF format. But the point is that the company should provide a URL that will provide that PDF, and other useful information. The included basic sheet states that this reader will work with eight different map scales...yet it doesn't even clarify which eight scales those are. To provide a list of those scales on that sheet, or online, seems like common sense to me. It seems very simple, and I'm sure I'll learn how to use this product very quickly. But, in this age of Internet, it surprises me that they don't have a detailed PDF and a how-to video on YouTube. Laziness, is what it comes down to.

Rated 1 out of 5 by from Protractor is useless, buy a better reader. UTM grid reader works if you pick the correct scale. But the protractor is printed like the ones Westcott makes for geometry class, where the angles increase in the counterclockwise direction. Compass angles increase on the clockwise direction. No idea what they were thinking, since there's no documentation with it except for using the UTM scale markings. Basic map and compass training, including military, teaches use of the protractor for plotting the intersection of two bearings to locate the grid coordinates of a distant object, using the protractor on a standard grid reader. Those angle markings always read clockwise, exactly like your compass does. So do most other plastic grid readers you can buy for the same price as this one. Do yourself a favor, and buy a better one than this, that's not printed backwards. Even if all you wanted was the UTM scale, why not carry one that at least works if you ever use the protractor? Maybe you'll even get some better documentation with it, since the doc that comes with this one is also worthless.

Rated 3 out of 5 by from good tool almost This is a useful product for most maps, unfortunately it doesn't work with the popular Green Trail maps sold at REI.

Rated 1 out of 5 by from Degrees Backwards?!? I bought this on a whim since my Military UTM plotter won't work on 1:24000 USGS maps, got home and realized the degrees starting on North are backwards. Not sure why you would want the degrees going backwards doesn't seem to make much sense.

Rated 5 out of 5 by from Essential -third leg of the navigation stool I bowed to technology and ditched the compass (actually still carry it) in favor of the Suunto Ambit. But the two other pieces will always be with me -map and this grid. Full size GPS are still to clunky and myopic for me. With your UTM coordinates in hand, you can pinpoint your location immediately.

Rated 5 out of 5 by from Great Point Position Tool This grid reader is a bit complicated at first but is very useful for establishing point position. I typically use it for 1:24,0000 USGS charts but it can do far more - including DMA maps of several scales. Not only a good training aid, but a good tool to keep at your chart table.
