micdsguy, I'm not so sure that Stalkers round to the nearest MPH. My experience is different. I used to own both a JUGS and a Stalker (I had the JUGS, then bought a Stalker Sport in 2003. I owned both guns concurrently for a few months until I was able to sell the JUGS). From what I have seen, neither the Stalker Sport nor the JUGS rounds to the closest whole number. Instead, the Stalker always shows the next lower number, while the JUGS always shows the next higher number. Thus, if both radar guns register 87.9, the Stalker will show 87, while the JUGS will display 88. If both guns register 87.2, the Stalker Sport will still indicate 87, and the JUGS will still read 88. Of course, the Stalker Pro will actually display "87.9" or "87.2" for the release speed of the pitch (not to mention showing both the "release" speed and the "plate" speed at the same time).
