功能:指北针/温度计/地图测距仪/钥匙挂件

名称: 地图测距仪

材质:工程塑料外壳

重量:26克

特点:

此款指北针上带有一个地图测距仪,即当滚轮在地图上两点间滚动时,测距指针随之转动,按照相应的比例尺记录此数值,乘以比例系数,既可得到两点间实际距离,比用直尺测量的直线距离要准确许多。

四种比例标尺模式、

1:1原始比例(外圈),1:50000,1:20000,1:5000,可以根据实际的长度来选择不同的比例标尺,只需将本体前端的滑轮片,在地图上从起始点沿路径移动至终点,然后根据不同的比例标准来测算两地间的实际距离

指南针使用常识:

指南针务必水平地拿着,而且要远离以下列举的各种物品,才可避免磁针发生错乱:指南针应离铁丝网,高压线,汽车和飞机,以及含有磁铁如磁性容器等
