PA BOWHNTR. I just have not been able to hurt one of those or cause it to do anything but work just fine year after year. I quess they have cost me about three dollars a year. So far I don't really know why I would want to spend more. You put the cross hair on the target and it hits it. The old Bushnell Sportview straight power line were the same way I had a 12X Silhouette scope with the auto range clicks for the different targets. Worked perfect for 12 years and thousands of rounds of 308 through two rifles. I then sold it for just about what I paid for it. I have a 3X9X40 Range finder Sport view that I have had for 30 years. This year I am going to send it in and have it cleaned and the adjustments checked. I have one of the 6X Sportviews left thats going on thirty years old and has been on some big rifles including a 416 Rem Mag. Still works perfect. They discontinued that line and replaced it with the Sportman line. I have not tried them YET.
