Thia is my first published video with my GoPro and I haven't mastered the camera angle and editing techniques yet. This was taken at Mermet Springs in Southern Illinois while my buddy and I swam through the sunken 727 in the quarry. The tail sits in about 20-25 feet of water and the nose dips down to about 55 feet (and below the thermocline Brrrr).
