First try with a Sony AS HDR 100V... This is filmed with regular 25fps mode and not in pro mode. Quality is still decent, surf mount is good, angle not great with stabilizer on 120 degrees isn't enough for this mount. Will try without stabilizer for 170 next time... quick release held a few min then cam flew of, good thing I used the leash. Gps data lags a bit (see speed) when we have some wind again I will try helmet mount.
