The Front Side of the Measuring Instrument comes with geographic coordinates and a scale.it has an engineering plastic shell which is solid and durable.it will measure accurately with the small wheel at the front end just moving slightly, and the simple design of rear handle make it easy to use and carry for going out.
When the wheel rolls between two points on the map, the ranging pointer will move it. then records the data according to the corresponding scale and multiple by proportionality coefficient. on this way you can get the actual distance between two points which is more accurate than the straight distance measured by ruler.
The map range finder is convenient and fast to measure mileage and distance, so it is specifically used to measure the actual distance of the bending routes map
Rangefinders allow you to quickly calculate the distance by measuring the distance between two points on the map.
Card measuring tool is made of high quality metal and plastic, durable, wear-resistant, rainproof and durable.
Nice gift for people who like to be active outdoors. Good for outdoor use, camping, hiking, cycling, hunting, etc.
The map distance meter tool is easy to use. Simply place the mini metal wheel on the map and roll it. The pointer would point to the exact scale.
This card measuring wheel is lightweight and portable and features a mini metal handle for easy hold.
Model No: WBB16617
Features:
The map gauge is used for route planning with a map as you put the bottom wheel in a right angle to the map,
Then you "write" the route you want to drive and after you can read on the scale how long the journey will be in kilometers.
The scales are 1:100.000, 1:75.000, 1:50.000, 1:25.000 at one side and 1:500.000, 1:300.000, 1:200.000 and 1:150.000 on the other side.
