During some recent filming over the Yarra River in Melbourne Australia, I had a near death experience. I was moving slowing downstream, observing my i1 from the bank, although it was very difficult to see because of the intervening trees and my elevation on the bank. All of a sudden the relative quiet was disturbed my the sound of my i1 changing from a constant hum into the sound of a lawn mover, cutting the vegetation. My heart stopped and I was just able to calm myself enough to not panic. I figured out I should descend slowly and was grateful to hear the noise return to "normal". It was only after reviewing the video that I realised how lucky I was. A excellent lesson learned, without paying the ultimate price. Enjoy. Hopefully others may be inclined to share similar experiences. It will be cheaper than counselling.
