POLARIS Waterdicht Micro- Kompas 2 Modellen/Horlogebandkompas of EDC-Kompas

i tried comparing it with my phone compass and other compass the difference it more than 10 degrees .

空気の入り易い某社のコンパスから買替え、正確に北を指してくれるので好いです。夜もハイビームを当ててやると視認し易い設計です。

nice

I have some Velcro straps hanging around so I threaded one through which lets me attach it to my bike.I bought this to go on my bicycle's handlebar stem but the stem bolt is steel so that didn't work.I then moved it to my aerobars (one advantage to using a Velcro strap) and it works brilliantly. It will also work on an alloy or carbon handlebar if you mount it away from the stem bolt. Orientation does not matter, it just has to be roughly flat.Some reviewers complain it doesn't rotate and that's almost certainly because there is iron nearby. Even attaching it to a watch strap won't work if your watch case is steel. But if you find the right place to put it, it will work great. It is slightly luminous, but only just.Very easy to read, good value for money, accurate. Checks all the boxes.

Parzialmente bloccata la rotazione, indica il Nord solo quando vuole. Pessimo acquisto
