Price Value Quality
JohnAn excellent piece of kit but it is technical to use. Made in the USA and comes with good guarantee. Build and ease of operation is good and these have become popular in my shooting team. I am looking forward to using more of the functionality in upcoming range days but beware as I've already attended some competitions where there use was banned. One final note of caution as the 4500 is very sensitive and the predictions are only as good as the data you put in!
