Took a little video testing out a chest rig for the GoPro Hero 9, up Palomar Mountain. I took the S6 up and S7 down to Lake Henshaw. I took a little drone video as well.
The S6 up is pretty tight and twisty. The 7 (East Grade) is a little more loose and flow-ie.
Not sure how I feel about the angle of the chest mount. Seems like it might be a little too low and include too much of the phone/guages in the shot.
