    Low spin on wedges tested against flightscope

    So i got myself a 2nd hand gc 2 unit with SN about 7500 and firmware version 3.5.1.0
    Just some info about myself: I'm currently a 4 hcp and practice a lot on Trackman and flightscope so i have a good understanding of my numbers.
    I tested it at home first and got very low spin numbers with wedges and irons from 8 and down. Thinking maybe it's the flash , so i changed it. (i got a spare one in the deal, but how do i know if it's used?)

    Took it to the the range and set it up together with a flightscope to test.

    Driver/3wood/hybrid/4.5.6,7 irons were all showing pretty matching numbers on GC2 and FS

    8iron to SW were way of with the SW being worst. Some examples:
    GC______FS
    GW 4460 - 10684 This was a brand new prov1
    PW 5672 - 11250
    SW 3666 - 8617
    SW 2790 - 5355
    SW3249 - 6378
    It was only the spin numbers that were off, launch and BS were matching the FS

    What is my next course of action? Tilt calibration, update FW?

      Wow, those are some low spinning wedges. My gc2 with lob and sand wedge are routinely 10k. Your display is showing total spin not back spin right? There is a menu option to change total spin to just backspin.

          Also were the carry numbers way off? I imagine a sw with 2800 spin goes really far.

              Yes it's set to show total spin with axis.
              And it's giving me about 15-20 meters more carry.

                  I'm not sure what it means but I would point out that several of those are almost exactly half of the flightscope spin number. Might be a clue for someone who knows more than me.

                  Both the tilt calibration and updating the firmware are easy and worth a shot.

                      Firmware won't do anything. That's really strange. I find my spin numbers deadly close when I run it next to a trackman or FS which I do from time to time. Tilt is worth a try.

                          Tried cleaning the lenses? Let me know if you ever figure this out as I feel mine reads a bit low too, but not nearly as bad as yours.

                              So i did run the tilt calibration and also upgraded to 4.0 FW.
                              First shot with a 60 degree showed 9560 spin :-) And it keeps giving me what i expect to be the right numbers. Don't know what was wrong but now it's working so i am very happy.

                              Will try it again with the flightscope in a few days just to be sure. (will report back)

                              Thanks for your help!
