My laser test across a frozen lake - 3 mile result

Set up a high-powered laser at a height of 2 feet on one shore and measured where it hit on the opposite shore 3 miles away. According to the globe model, the beam should have been about 6 feet above the surface on the other side due to curvature. It hit at exactly 2 feet. Full documentation in photos below.

Incredible results. I want to try this when the lake near me freezes this winter.
