These videos prove how much differences there are during different days of visibility. The last part proves to me that the surface of the water is mainly flat and level. The first video the height of my camera was even higher than the second video but yet I was able to see objects well beyond the distances of what mainstream science claims. These are my personal observations and I have no reason to lie about the height of my camera. So you be the judge for yourself. Thanks for taking the time to watch.
