MapWheel 7010009 Digital Map Measurer; 19 Built-in User Scale Factors Including All Common Map Scales; Measures in Miles, Kilometers, and Nautical Miles; Easy-to-read Liquid Crystal Display

This is the coolest tool. So far I have used it to find the shortest distance on my regular trips. Some of my travels are not direct main road routs and using the map wheel has cut up to 10 miles off some of my "back road" travels. Its even a fun "final word" when several people say they know the shortest rout. This tool can be set up to measure any distance on any map. I can also see it as a blue print reading tool - 1 inch equals 1 foot (mile)or any scaleing applacation. Its quick, easy and more versital than map quest. Jim

Very simple and easy to use. I needed it for mapping out the shortest distance for plotting a newspaper route. Worked wonderfully, saving me extra miles on my car, extra gas, and countless hours driving. Google was far too complicated to try and figure out the shortest distances. I would have spent hours just typing in all the addresses on my route. This mapwheel allowed me to just roll it over a map and plot the most efficient line of travel.

I bought this thinking it could be used for blueprint takeoffs. The description shows it is completely scaleable, but that is not exactly accurate. This is a digitizer for geographical maps only. There is nothing wrong with the device as I see. I either didn't read the description well enough, or the description was inaccurate. When I went to use it on a large construction bid, it would not scale to my blueprints. The return date had already passed, so I guess I own it now. Big waste of money for me.

Very disappointed!I tried following directions to set scale however still have not been able to use as intended.Too complicated as well as wheel too sensitive to measure on maps, even one inch to 40 miles.Sorry I spent so much, I would have been better off buying an $12 manual wheel map measured.

ok product

Easy to use even when the instructions can be a little confusing. I already used it in measuring a trail in a map that don't have standard scales. It work really nice and help me plot a route for a 15 miles hike I am planning for January 2018. Be aware, the measurements will be as good as the time and ability you have to follow a trail drawing in a map so, what you are getting are very close estimates. To avoid surprises will be better to take the highest and lower numbers and use it to calculate an average. The construction of the Scalex is in plastic and made in China so, if you drop it there is a good chance that render it useless. Just be careful when you use it and definitely do not take it in the trail with you since humidity may damage it as well.

What a great device. I use 7.5 minute topo Quads to hike in the wilderness and this device helps me plan my trip and how far it is to each location. What a great way to plan and prepare for the trips. I have enjoyed learning to use it. This one also is much easier to use than a manual map wheel.

Scaled for any USGS map and very easy to use!
