From the top of the shoulder to the bottom of the body of an elk is on the average 25-27 inches.
Looking at that picture, it looks like 2.8 mils from the top to the bottom of the valley. That would put it between 245 - 265 yards.
At 508 it would be about 1.5 to 1.34 mils.
But its just an advertisement.
