I recently am experiencing wedge & iron shots being way off. I have the latest software & firmware. I normally hit my PW 140-150 carry, today it was a struggle to get it up to 130 carry. The longer clubs seemed fairly normal. LW->8 seem off by as much as 20 yards. 7->6 seem off by 10 or so.. 5->DR seem ok, for instance was getting 220-230 carry w/ 4 iron, 270-280ish carry w/ driver which is normal when I'm swinging well. I used to get the same numbers on my SkyTrak that I was getting on GC2 @ my Golftec lessons ( I took like 80 of them - I've seen a lot of shots on a sim ). Today PW 120-130 carry. All I gotta say is - no f-in way, that's my typical SW distance, GW 130-140, PW 140-150, etc. These are the numbers I play for outside playing 2-3x a week during the season as well. It's not my swing being 'off' today for sure, I hit some really solid shots w/ shorter clubs that came up way short playing 'The Golf Club' - as well on the SkyTrak range. I also know someone who recently purchased a SkyTrak and is having the exact same issue (though until today I didn't know why he was having that issue) - he took the SkyTrak w/ iPhone to a local indoor simulator facility w/ high end equipment and SkyTrak off by 20 yards w/ his PW on the short end (same as mine). It was only recently I am seeing this issue, I used to see very similar numbers w/ my SkyTrak that I saw on GC2 & when I play outdoors.
