This simple pipe viewer is wonderful. It spins and you look through it to local mountain peaks. The pointer on the bottom tells you the peak you are viewing. So simple and COOL! It was very overcast and this made picking up the peaks in the distance a bit easier. We were on top of the world here. We actually looked down to the electric wire safety balls. You know the orange balls they put on the electric wires to keep aircraft from running into them and to steady the lines in windy areas.
