Your problem is that you are working with a bushnell.
I had borrowed my dads 400m one and was hunting sheep last year. I was looking at some sheep across the Fraser and was trying to range the hill (white sandy slopes), with the sun glaring off it, it looked like snow. I figured it was about 350-400m and I zapped it with the RF. the first reading came back at 83m
the second, third and fourth did not register. The 5th reading came back at 1840m
. If I could have reached the Fraser with it, it would have gone bye-bye.
