easily to handle, and top in perspective

First I had the headband attachment for GoPro Hero 3. This is actually quite good and most of all cheaper. But if you do so much (and afterwards looks) will be easily seasick, because the camera so every movement of the head. This may at times have a good effect, but in the long run this is something an effort to see.

This chest attachment is there much quieter. I use them very much to document photoshoots. From this perspective, one sees oneself namely quasi themselves at work and can change the camera when you are working with several (photo) cameras, and later witness and possibly even see the images on the monitor the cameras behind.

I use them here in the "medium" setting from the image. And make sure that the GoPro is screwed something slightly tilted forward. Then you definitely hands-off, and the pictures are not quite as hectic as from the end position. Sometimes you just make sure that you also slightly rotates with the body, when what you want to see the left or right would have on the recording later.

I can as a standard attachment only recommend the part.
