The other day, I bought a compass at a one 100 yen coin shop.

It is the compass of spherical floating in the liquid in the round transparent plastic.

I think it's great invention for everybody.

I need the compass without being levelled, as a key holder.

Since the recent smartphone has also been equipped with a magnetic sensor, if I use it, there is no problem. But I am involved in the use of cell phone even now,I have to count on a printed map

I think that I am good at reading loads on map, though, I am afraid that my feeling of the reading become worse.

However, even a paper map, and if only the direction is known, I can improve the understanding the place more.

"This great thing is just 100 yen" is really unbelievable.

It might be useful at a disaster. If a smart Phone exhaust electrical, it become a just paperweight. Even if you know even the direction at this time, you can start walking towards a certain direction.

I say something, however, I know well, "using smartphone" is the best answer,
