Chest Mount Harness to use with you GoPro camera. I use a Hero 3 so i´m not sure how it will fit newer cameras like Hero 4.The Harness Lock might be a bit bulky and maybe not the most clever solution but it works and i´m sure someone can come up with a great replacement!If you are thinking of using this it´s important to consider the conditions where you are about to use the mount. High or low temperatures for example can affect the durability of such a mount to the extent that it can break.Unfortunately there are so many variables that affects the quality of a print so i think it´s also important to say that if you use this mount it´s at your own risk. If unsure maybe it´s better to just buy one in the store.www.danielnoree.comhttps://youtu.be/KpWhszjRqoc
