This is Yardage Pro Sport 450. It is about three years old and had very light use. Displays yds or mtrs. In as new condition with its own soft case and belt loop all coloured black. No box or papers.
It measures four inches by three and a half inches by two inches and weighs eight ounces. It will give reliable readings out to two hundred yards on large solid objects (tree, wall, rock etc) but is not suitable for ranging an individual deer at any meaningful distance. I have mainly used it from a high seat for establishing range markers. I also use it for accurately measuring range to target when testing ammunition or setting up a scope.
In my view it is more suitable for air rifle, archery or rimfire distances. Very effective at one hundred and fifty yards.
